    Talking Good Views



    After months of trying (december-july) i have finally accurately aligned my 4.5 inch reflector mirrors. I got my scope in october 2010 and since then I have been collimating the mirrors, but not properly, hence the reason i got poor views. I took it out for a test early this morning 2am to look at Jupiter (which I had not looked at since February) and the views were just wow ! I cant think of another word to describe it. It focused into a perfect disc at 40x and it was sharp and bright and I could just make out the NEB and SEB at just 40x. I moved to 100x and I made out the STB and NTB and design in the Bands but GRS was on the other side. 200x was the same detail as 100x but slightly darker(thats expected)
    That night, I was in luck. The moon, mars,jupiter and pleadies all up on the same early morning. The moon was packed with detail even at 200x the detail was sharp and bright. It was my first time looking at mars and the pleadies, Mars was a pinky-orange disc with some dark makings, not as good as Jupiter but the fact im looking at another world is enough. The pleadies was tough because the min magnification i got is 40x and that was too much. It could not fit the full view but was still good. Such a good night im only 15 and i was up from 2-6am in my garden. Went back to bed happy.
    Having said that I was just thinking if there is a way to make your own eyepieces. If its possible, I would need your help.

    Thank-You

    Great stuff MrMan; your experience takes me back more than 50years when I was at a similar age, and my 3" reflector on my parents back yard in a rural dark sky region. By the time I was 17, aperture fever began to bite and had ground a couple of mirrors, 6"f8 and 7"f7.5, about which I built a scope with EQ mount. (Looked like a canon, and seemed to weigh a ton), but the views were unforgetable. Currently grinding 22" f5.2 and 25" f4.6 mirrors as a retirement project. (I call it "pupil enlargement".)

    Enjoy your journey.

    I had a friend trying to make a 30" Dob. I called him crazy, so he went on to grind hes mirror and somehow ended up with a long scar along hes right arm. Don't know how thats possible. I would want to learn how to make my own eyepieces though that would be a challenge.

    If you don't have anything good to say, don't say it at all.

    I think it is easy to do, just an aluminium or plastic tube with a calculated lens power that you can do in any optical laboratory for eyeglasses.
