Notes and Interesting Articles About DayStar Products

  • "A Solar Telescope - for Lovers of the Sun" by Michael Olshausen. The Questar Solar Observatory system was developed by a local customer of Company Seven with the cooperation of DayStar Filter Company, Questar Corporation, and of Company Seven. The system mates a compact Questar Standard telescope with a DayStar Hydrogen-Alpha filter to provide and extremely portable Solar Observatory. This is the article prepared by Mr. Olshausen for publication in the Company Seven "C-VII Journal" describing the development and operation of the system.

  • PDF Icon "The DayStar Filter - Hydrogen Alpha UNIVERSITY and ATM (Oven Models). A complete illustrated instruction manual in Adobe ".pdf" format, as is produced by Company Seven for customers who buy the DayStar Hydrogen Alpha filter from us. Some details may vary from filter to filter, and so this publication should not be considered as providing those settings that may be entirely appropriate to your particular DayStar filter. This manual outlines solar observing, describes and illustrates the components of a DayStar Hydrogen Alpha filter system. We also provide some application notes facilitating set up and operation of the filter, how to predict fields of view, how to use these systems visually and for imaging. This publication is not applicable to the DayStar Calcium K-Line filter series however, Company Seven does provide an entirely different manual for our customers who choose to buy that filter series.
