Nice moon shot Ivorie. Since ypu are shooting K20D put it on 3 second mirror lock up and use the wireless remote. Can make a world of difference. Most tripods don't settle down in 2 sec with that kind of magnification.
Remember to clean the front corrector plate differently than normal lens. Should make straight "spoke like" movements with the cleaning cloth. Not circular.
Questar used to make a Mak camera lens. Don't know if they still do. All their telescopes are Mak. These are expensive but as good as it gets for that type lens. Maks take longer for the optics to settle down in temp extremes.
Love my Celestron C5 (1250mm f10). Much better than the C90 I had. Old C90 didn't have the new multicoatings (star brite). Big deal with lower contrast mirror lenses. Have to post a shot with the lens when I get the time.
thanks
