Quote:Hi Dave, Welcome to Cloudy Nights! Glad to have you join us.Congratulations on your new 8" Dob. This scope will show you great views of the night sky. I would recomment taking the PDF file for the 22" into Staples, etc. and have them downsize it to fit your base.Let us know how it turns out!
Quote:The larger the degree circle is the more accurate you are able to determine smaller increments.
Quote: Depending on which part of the sky my scope is pointing the target can be off by a full degree or even more. The object will often times not be in the fov of the eyepiece. It will, however be in the fov of the finderscope.
Quote:Thanks. I think the accuracy will come down to careful centering of the circle. No different than marking a center spot on a mirror really.
Quote:and the mount & scope orthogonal
Quote: That's only one variable. The mount needs to be completely level and the mount & scope orthogonal. Pointing error increases with increasing altitude when mount is not level.
Quote:Ok, I did it. Not sure why I found it so nerve wracking, went pretty smoothly.2" hole with desk grommet. Used red wire notched into the grommet for the indicator. Still trying to find a clear cover, maybe even a magnifying lense.
Quote:I know a lot of people got their circles printed @ Staples or a Kinkos but does any1 know if Office Max has and will do this?
Quote:Quote:I know a lot of people got their circles printed @ Staples or a Kinkos but does any1 know if Office Max has and will do this? well to answer my own question, yes they do. I was just there and it cost me 7 dollars and 82 cents.. That was with the 20% off bag sale they are having.

Quote:What should be the proper orientation of a degree circle markings should I use, CCW or CW on top of the box board? Carol, in your attached photo, it appears that you have it both ways. Thanks. shien
