9 August 2007 Company Seven Acquires Biosphere 2 Astronomical Observatory. This is designated our 'MCCM' Observatory Project. The system will be relocated to Maryland and established as part of our own science education facility.
20 March 2007 Company Seven supporting NASA annual 'Sun-Earth Day 2007' educational activities. This year's theme will be "Living In The Atmosphere of The Sun".
20 March 2006 Company Seven supporting NASA annual 'Sun-Earth Day 2006' educational activities. This year's theme features natural and artificial eclipses!
The system furnished by Company Seven was our Astro-Physics 206mm f/8 EDF telescope with a Astro-Physics 90mm f/5 Stowaway "finder" telescope on an Astro-Physics 1200GTO German Equatorial Mount. The system was equipped with our Baader Mark V Großfeld Binocular Head, a top of the line system providing high resolution binocular views through the telescope. We employed a selection of TeleVue Panoptic, TeleVue Nagler, TeleVue Radian, and a matched pair of Carl Zeiss Abbe Orthoscopic series eyepiece sets and filters. While this was a good "practice run" for us, the seeing conditions were marginal with notable humidity and sky glow. Therefore, the telescopes were limited by seeing conditions to moderate magnifications on the order of 300X or less. Regardless of the seeing limitiations, the large number of visitors were nonetheless enthralled by Mars. Later in the session we did study a number of the brighter popular deep sky objects, and later Saturn!
As described by the AMU staff "technology is driving a revolution in amateur astronomy. Improvements in telescopes, computerized data, cameras, and more means backyard stargazers now have access to information that only a few years ago would have been limited to the hands of experts. A look at the technology of amateur astronomy -- and what you might discover by just looking up."

Recent Changes at C7's Web Site
Much has been going on at Company Seven over the recent months, but since we are foremost showroom oriented and not primarily an 'E-tail' based shop and since our people have been spread thin overseas on other work we do, we have not been able to provide much attention to our Internet site as we would like to. You can contact or visit our showroom to see these, and in time we may post detailed illustrated reviews of these 'hot' new products on line. But for a taste of some of our most favorite recent news here goes:
The Pricing of the instrument set is $17,500.00. We have updated our availability information for this product on line reflecting we are accepting orders for deliveries starting in late 2010 and continuing into 2011.
The first item we feature is the famous Nikon Rayfact UV-105 F4.5 Lens that is offered in the Americas through Company Seven by special order. This lens bears the 'NikonRayfact' designation, but it is a current Nikon production lens that replaces the original UV-Nikkor (PN 1453) that was introduced in September 1985. The UV-105 lens is an exceptionally sharp 105mm f4.5 conventional lens with macro (2:1) capability too. However, this lens is most acclaimed for its usefulness from 220nm in the ultraviolet up through the visual spectrum and into the near IR at 900nm. This this is a preferred lens for forensics, medical studies, electric discharge studies, research, or for the more dedicated amateur who seeks to explore portions of the world invisible to the eye. This lens is provided with the Nikon F mount and as such can be attached onto any Nikon SLR film or digital camera, or onto a Bellows or other fixtures. We will gradually describe more and more of the limited production Nikon products as we develop our Nikon section on line.
This Nikon UV Lens is complemented by our afused silica Long Distance Microscopes that can provide resolution in the visual and UV spectrum down to the sub-micron level.
The Pricing has not changed. We have updated our availability information for this product on line reflecting we are accepting orders for deliveries starting in late October and continuing into the Fall 2010.
Changes up to July 2010:
Much has been going on at Company Seven over the recent months, but since we are foremost showroom oriented and not primarily an 'E-tail' based shop and since our people have been spread thin overseas on other work we do, we have not been able to provide much attention to our Internet site as we would like to. You can contact or visit our showroom to see these, and in time we may post detailed illustrated reviews of these 'hot' new products on line. But for a taste of some of our most favorite recent news here goes:
We have signed an agreement that will result in the installation of the The MCCM Astronomical Observatory in Maryland. A formal announcement will be forthcoming. Note, all of this has been accomplished with not a single dollar being donated (even in response to our invitation), with no public funding (even though desired by them, local governments have become cash strapped and could not assist), and with no formal organizing effort. The final arrangement for the operation of the observatory makes even better sense than simply donating it to one or another school district since our choice will provide years of continuous competent support of the observatory, and development of outreach programs.
We are grateful to Doug Humphrey and to John Stiles the owner of Optical Guidance Systems (who built the telescope). This might not have happened without the help from Doug, he provided sound advice and a warehouse in which to stage the telescope and parts of the observatory while we and John worked to put it back into service. And of course we are happy to be working with the organization that will host the observatory, but more about them later.
Changes in May 2010:
Changes in March 2010:
We also added the Orion EON 80ED, an affordable (~$600) compact and multipurpose f/6.3 apochromatic refracting telescope that has become quite a popular and handy compact telescope at Company Seven. With actual fields of view with eyepieces of up to 5.4 degrees at magnifications as low as 12X; this is suitable even for panoramic work, wide sky applications including use as a superb finder telescope. Furthermore, its overall good qualities allow higher magnification work that provides clearly identifiable views of the major changing features on the planets.
Being so impressed with the value of the EON 80ED we also put on display the EON 120 ED, a 120mm (4.7 inch) aperture f/7.5 apochromatic refractor. The EON 120ED with its noteworthy increase in light gathering power over most 4 inch Apos, but selling for about 1/2 the price tends to make up with size what the lens may lack in overall performance and as such will attract many people back to Apos who seek a 4" Apo but can not afford our top line 4" apos. Furthermore, at low to mid magnifications this ~$1800 telesocope brings in visual deep sky images better than even our better 4" apos owing to the 22% increase in light throughput of the 120mm lens compared to most better 102-105mm class apos. And at f/7.5 the telescope remains handy, and can work well with a broad selection of less costly eyepiece designs even though most customers buying this telescope do recognize the value of investing in premium eyepieces. The EON 120 ED includes hinged Hex mounting rings and a V series mounting plate; these make it suitable for many applications even as a guide telescope or it can easily accept an optional photo-guide telescope.
The EON 80ED and the EON 120ED are fully machined well thought out telescopes. Each is provided with a 2 inch diameter Crayford style focuser, with dual speed geared focus control - and the entire focuser can be rotated to facilitate composition when imaging with film/digital or CCD cameras. An optional field flattener lens (for imaging applications) is among the available options. Each of these telescopes is furnished in a nicely made, comparatively light weight metal-clad and foam lined carrying case.
Company Seven is now accepting orders for the portable Mach1GTO mounts. These will be completed for delivery between April and July 2010. We have been working on the custom design of a new Airline Transport Association Approved carrying/shipping case for the Mach1GTO head and accessories since September 2009! But it is only in recent days after making several prototypes that we have settled on the optimum arrangement for this new case. We hope to have the first case completed in another week or so by mid March. Once we sort out what our costs have been to get this far then we will be able to quote a price for this new product.
We updated our Astro-Physics Products Availability information page to reflect this and other developments.

When we opened there was a telescope shop operated by an enthusiast ("Tuthill the astronomer's friend", etc.) in almost every major city. However, by 2009 Company Seven finds itself among the very few and longest lived competent astronomical telescope oriented specialty showrooms left in the Americas. Throughout this time while others promoted themselves ('bigger', 'cheaper', 'snazzier', 'order now on-line') we outlasted most of them by simply promoting our hobby. We have helped to establish astronomy clubs in schools and communities in the USA and overseas as well. The name 'Company Seven' is synonymous with uncommonly high standards of integrity and competence, and for unflinching loyalty to those who have elected to associate themselves with us.
We are not sure who should thank who the most: our customers thanking us or us thanking our customers but every new acquaintance has been a privilege for us and we are happy to know we can travel the world and meet friends who share our passions. Thank you!
Unfortunately for us there is too much work to do, and so do not look for any parties or back slapping at Company Seven this month.

* The original announcement included the Geovid HD models however, Leica later issued a correction notice stating these would not be in the rebate. As a tangible expression of their regret Leica agreed to honor rebates for Geovid HD but only of sold by Company Seven through 25 May.
To claim your rebate simply fill out the Mail in rebate redemption form, include a copy of the Company Seven sales receipt along with a completed copy of your product warranty registration card (included in every new Leica product box), then mail it in.
Changes in April 2009:
Using light waves the LightSpeed technology transmits voices in the field of view of the binoculars up to a distance of 1-½ miles (2-½ km) crystal-clear, without any interference, day and night. Even data such as text or images can be fed in via the USB port and transmitted at a rate of up to 1 Mbps. This development has evolved from a cooperation arrangement with the well-known secure electronics development company in the USA. This form of bug-proof communication offers special police and military units a wealth of tactical advantages. The extremely compact yet powerful LEICA GEOVID LUX 8x 56 also has further application potential in stalking, industry and rescue services. US and allied governments agencies should contact Company Seven to obtain our DLA or ORCA information.
What will they think of next?

To learn more about how impressive this handy chart is, browse the DeepMap's more than 600 contents: Deep-Sky Objects Catalog, Double and Multiple Stars, Steve Gottlieb's Top Variable Stars. These can be found in our Library Orion Notes & Interesting Articles page. For the inexperienced beginner we also recommend acquiring the large David H. Levy Guide to the Stars Planisphere.
Also added on our site an improved Leica Accessories for Binoculars and Spotting Telescopes index page. This links to several new articles: Leica Binocular Tripod Adapter, Polarizing Filters for the TELEVID, UV Protective Filters for the TELEVID, a well illustrated discussion of the brilliantly engineered and simple to use Leica Digital Camera Adapter used for 'digiscopy' (or 'digiscoping') with compact digital cameras or cell phones ('phonescopy'?). Of course, those demanding the best results with digital or film SLR camera can use the Leica SLR Photographic Camera Adapter.
While we were adding information about the new Leica APO-TELEVID 82 we dramatically revised and expanded our reviews of the Leica Leica Binoculars. And unfortunately, we also revised Leica Pricing section to reflect 1 January 2009 changes and new products.

Pricing and availability information for this product are now on line, and we are accepting orders for deliveries starting in late September and continuing into the Fall 2008. It is planned that Company Seven will order one for display in our showroom and so you will be able to see it here. However, we are not certain how many more of these mounts will be made in the near future, so we encourage those who seek a premium mount at an unrivaled price order from this current production run.
Changes in July 2008:
For readers interest, and to aid clubs who plan to build an observatory we added another Image Gallery illustrating the Disassembly of the Biosphere 2 Astronomical Observatory Telescope and Dome from 22 to 25 June 2008. We then loaded the facility and transported it to Maryland, arriving on 27 June. The shipment was unloaded into a storage facility on 30 June.
So now we own and posses the Observatory telescopes, Dome, facilities, blueprints, and images that document this process. This documentation should make the disassembly and reassembly go much more quickly and uneventfully.
Changes in June 2008:
For readers interest, and to aid clubs who plan to build an observatory we added Image Galleries sections illustrating the 1999 Construction Of The Biosphere 2 Astronomical Observatory Facilities, and Biosphere 2 Astronomical Observatory RC-24 Telescope Installation.
So now we own the Observatory telescopes, facilities, blueprints, and images that document this process. This documentation should make the disassembly and reassembly go much more quickly and uneventfully.

Changes in February 2008:
In keeping with our goals of conservation and documentation we have prepared an article Criterion RV-6 Dynascope: these introduced many of us to visual astronomy. The article describes the RV-6 acquired by Company Seven, the RV-6 as it changed over the decades, and some history of the Criterion Manufacturing Co. who made this telescope, and provides insight into the evolution and marketing of these types of instruments from the 1950's through the peak of the Apollo space program, and into the 1980's. The telescope is likely to be conserved and not restored to like new, but over time as we learn more about it then we will edit the articles to share the information.
Furthermore, in a rare collaboration we have arranged permission to use images taken by Tom McDonough of the restoration of a Criterion RV-6 at Criterion RV-6 Dynascope Restoration Gallery. This was a lot of hard work but for a subject close to the heart, it is worthwhile.
Incidentally, the Fujinon 10x 70mm MT-SX binocular illustrated by us in our review actually FAILED Company Seven's in house inspection process, and it was returned to the manufacturer. Look at the image, can you find the anomaly? We are amused that most E-tailers never even see the box, while a few other shops claim they check what they sell yet few return anything to the distributor. Now, where will you buy your own binocular or telescope?
Over 2007 our opinion of the 'is' accessory products changed as we observed the system become more refined and expand into a more comprehensive and better performing solution. And frankly, several of these telescope are just too good not to feature for our clientele. And so in the interest of supporting C7's customers who are buying 'is' telescopes, we made the effort to demystify the system. Writing these illustrated articles was a bit of a Herculean task since the system is at first glance confusing, and even the initial materials provided to us by TeleVue were simply overwhelming. Regardless, our result will be helpful to our customers.
And another article that is more relevant to today describes the Deluxe Leather Case which may be ordered as an upgrade in place of the standard Vinyl-Clad Case when ordering a new Questar Questar Standard or Duplex astronomical telescope. The leather case is provided as part of the standard equipment with the limited production Questar 50th Anniversary Model telescope.

Also added a new publication "Remote Control Astronomy Handbook" to our Technical Innovations Notes and Interesting Articles index page. Until now, there has been little printed information available on creating and operating robotic observatories with contemporary observing equipment and computers. This illustrated 57 page booklet as a service to the astronomy community by drawing on the experiences of the authors and that of our customers. This booklet will help you learn the practical side of operating a telescope and observatory by remote control. The Remote Control Astronomy Handbook describes how to automate an observatory including sections about the observatory, the telescope, cameras and computers. It is intended primarily for astronomers at the advanced amateur level and for professionals who need some orientation to the subject. Published March 2002 by John and Meg Menke, of Menke Scientific, Ltd. Copyright John & Meg Menke, from Company Seven's Library. Download size is 505,058 bytes (in Acrobat Reader ".pdf" format).
As a side note, Company Seven's primary area of work is for Government and industry; the profits from this work have historically permitted our staff to operate the astronomical side of our business in a rather idealistic manner. However, recent demands upon our most capable staff, including extensive travel to overseas, have left us lacking the people to maintain and update this Web Site as we would routinely have preferred to do. Furthermore, we can not simply trust hiring a "Beltway Bandit" with no knowledge of our industry to maintain the site and provide the valuable and insightful content. So we ask for your patience as we adapt to the changing demands made of us. Note, our routine practices and our showroom operations continue unabated.

And to show a token effort to support our Birding clients (we would not wish to compromise our credentials among the astronomers) we revised our discussion of the Questar Field Model telescope. And we describe the new Questar 45 Degree Image Erecting Prism.

The Planisphere makes it very easy for one to find out what constellations and major deep sky objects are up overhead at any given time of the day or night. These are made in two sizes 11 or 16 inch diameter, available in either English or Spanish, and for use in either Northern or Southern Hemispheres. These are a two piece plastic disc assembly with a map of the entire night sky one the rear chart disc, and another overlay disc attached over the chart disc. The overlay has a transparent window with a surrounding mask to simulate the North, South, East and West horizons. The overlay is dialed to line up its local time indicator marks with the Month and Day printed around the edge of the chart disc, and so when properly set this will reveal what parts of the sky may be seen at any time of the year. We prefer the larger 16 inch model because the writing is larger and easer to read under red flashlight. The print is black lettering against a white background sky and is easy to read under red light.

The Clear Sky Clock we feature shows a prediction of when the area around the University Of Maryland Observatory in Adelphi, Maryland will have good weather for astronomical observing. The Observatory is quite near to Company Seven in Laurel and so we employ this clock as a public service for our readers. We did not realize that the author's links had changed some time ago, and so we apologize to our readers for our oversight.

Changes through December 2003:
1. Often the volume of incoming E-Mail that requires our writing a detailed technical reply precludes a more prompt reply to other E-Mails by Company Seven. We are happy to offer sound advice to those in need, and E-Mail can be good for this use especially for more distant customers. However, E-Mail is in some measure abused by some who have forgot how and when to use a telephone. Aside from the volume of inquiries, E-Mail is also subject to problems with some who accidentally provide an incorrect return E-Mail return address; there have been times when we send an E-Mail reply and it is returned or blocked by the customer's automated spam filter.
Over recent years we have assigned additional resources to meet the high and increasing demands brought about by the Internet, and by increased word of mouth exposure. However, it is often impossible to reply to all inquiries, or to inquiries that we judge to be answered better with a simple phone call. So, when you do require a prompt reply to an urgent matter then please either telephone our showroom on 301-953-2000, or E-Mail and be patient. If no reply to your E-Mail arrives within a few days then you may send it again.
2. On 16 December we completed hardware and software changes to our E-Mail system. So those E-Mail's that arrived between 7 December and 16 December were received, and stored, and we are gradually working through the backlog as well as new E-Mail inquiries. We apologize for the inconvenience or undue concern.
3. The recent Mars Opposition and conservative planning by manufacturers has resulted in shortages of supply of several popular telescopes, especially those which are most popular among those entering the hobby. While the demand for new telescopes by customers contacting our Laurel, Maryland showroom has increased particularly dramatically over the past weeks. And so for new orders received after 1 December 2003 we are reserving inventories of several of the very popular instruments for pickup at our showroom only. We will continue to accept mail and phone orders for both delivery and local pickup, but those new orders placed on 1 December or later are not likely to be shipped out until after the Christmas rush, probably in January 2004 or possibly even later for some instruments. This will reduce the chances of our having to deal with shipping related losses in transit, and will make virtually every telescope we accept available for pickup in our showroom.
Company Seven has been aware of this new product series since it was announced in August 2003, but we decided to wait until we could actually evaluate production models before we published our review. You may now read about the ULTRAVID 42 BR, ULTRAVID 42 BL, and ULTRAVID 50 BR models on line, and see these instruments in our showroom.

In collaboration with partners that include science centers and museums around the world, the Exploratorium, NASA Connect, Sun-Earth Connection missions, Company Seven and others, NASA produces webcasts, other multi-media, and print resources for use by school and informal educators nation-wide and internationally. The NASA Sun Earth Forum provides training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources. A coordinated approach promotes multiple programs occurring each year under a common theme. The Sun-Earth Day website contains information for students, educators, scientists, museums and amateur astronomers! All web resources for prior events such as "Sun-Earth Day 2005: Ancient Observatories, Timeless Knowledge" are archived and will remain on-line for your enjoyment!
