Re: New life for a 29 year old Astroscan

Mike,
Thanks for the kind words. I did not know if there would be any interest in the Astroscan repair, but since I found little info searching, I thought I would share what I have learned
For Helpwanted, the FOV with the std 28mm RKE EP is 3 degrees. Even more interesting is the FOV with a TV 7.4mm Plosssl is 0.8 degrees....quite impressive at the given 60x power. I find it necessary to use the eyecup with the 28mm EP, as your eye has to be centered for that particular EP
I have seen satellites (thorough the EP) before while observing, but rarely. Using the Astroscan last night, I counted 9, including one pair travelling together, side by side
While scanning through Sagitta last night, I noticed one star that looked like a double at 16x. At 60x, the Astroscan clearly showed the pair. Lacking any way to measure the seperation, I could only estimate that perhaps 4 stars could have fit into the space between the pair, and I was impressed with the optics on this view.
One thing I would like to add here. I find that the little scope is such a joy to use, that the "quick look" I had planned turns into a 2 hour session. It is partly because of the nice wide views, and partly because of the simplicity in scanning with the scope. The name was well though out, as was the design
