Company Seven.

Company Seven is a resource for the international amateur and professional astronomy community, and a registered U.S. Department of Defense contractor. A hub of the regional amateur astronomy community, we also consult to a number of organizations including for and not for profit media. Our credentials include support of mission critical aspects of: NASA Hubble Space Telescope Repair Mission, the NASA International Comet Halley Watch, the NASA James Webb Space Telescope, and a variety of defense and law enforcement projects.

Our ethic revolves about a philosophy of high ideals and good public service where profit is never the overriding concern. Our customer’s success is based on our offering counsel and very good to excellent products, some of which are very rare if not impossible to find elsewhere. Our staff is unexcelled in technical competence, and we provide a high degree of in-house quality control, and comprehensive programs of instruction.

We maintain one of the last remaining and longest enduring astronomy-oriented showrooms in Laurel, MD between Baltimore and Washington D.C. This incorporates a museum of rare and antique optical instruments. Also featured are a representative selection of the better amateur and institutional astronomical telescopes, nature watching and surveillance instruments, binoculars and accessories. Our showroom is open Monday through Fridays 11 am to 6 pm, and Saturdays 11 am to 5 pm. We are close Sundays and U.S. Federal Holidays, and from 25 December through 1 January.

Owing to flooding of 21 June 2021 our showroom has been vacated while repairs proceed. This will not hinder processing or deliveries of pending orders. We discourage visitors except by appointment. We maintain core hours on telephone and in person Monday to Saturdays from 11 am to 3 pm, as repairs permit. We hope to reopen late in December. We apologize for any inconvenience to our community.

For the benefit of those distant, the Washington, D.C. time and date are now:

We fondly remember:

Bruce Roy Wrinkle (b. 7 August 1945, d. 28 April 2013) was the soul of our showroom; kind, witty, intelligent, and able to greet you with a funny joke. Bruce was was amazingly well read, able to hold conversations with doctors and scientists on matters from prions to dark matter. And he was our friend, a true friend in every sense of the word and every day without him lacks some luster.

And Robert Kim Carter (b. 18 Jan 1962, d. 23 April 2005) whose friendship and support originally brought this site on line in 1994. Robert founded one of the first Internet Service Providers of "Internet Valley", Digital Gateway Systems, Inc. in Vienna, Virginia. DGS used to be to ISP's, as Company Seven is to our industry.
