Re: Achieving Focus with a Zenithstar 61mm and Quark Chromosophere

Quark is designed to work with a 2" diagonal which has optical path length of about 130mm. So, if you use an 80mm extension tube and rack the focuser out about 60mm you should be in the right ball park.

Excellent results Alfred. Just a matter of time with the perfect tuning. Hi Dennis, I wish there is a inexpensive way to measuring on-band tilt instead of tilting by trial-and-error :D Alfred There is Alfred and you can do it already... When the image is on band it has the highest contrast, ie the ...
