glowingturnip Posted March 7, 2014 Share Posted March 7, 2014 i may be wrong, but looks like the collimation is way off there ? I think you can see the secondary mirror of your scope to the right of that central star Link to comment Share on other sites More sharing options...
Rudeviewer Posted March 7, 2014 Author Share Posted March 7, 2014 Yup I found it to be wayyy out. I was wondering why I had star halos everytime. My wife helped me make an artificial star with a led flashlight and a piece of cardboard. Found it was so far I could not believe it. So I think my new pics should be pretty nice if the weather ever permits lol. Thank you for confirming what I thought was the culprit. Link to comment Share on other sites More sharing options...
Rudeviewer Posted March 7, 2014 Author Share Posted March 7, 2014 The only other thought I had was the DLSR being to close to my focal reducer for the SCT. Link to comment Share on other sites More sharing options...
glowingturnip Posted March 7, 2014 Share Posted March 7, 2014 yet more expense I know, but I use one of these laser collimators - makes it an absolute doddle, you can collimate in seconds every time outhttp://www.firstlightoptics.com/hotech-collimation-tools/hotech-sca-laser-collimator.html Link to comment Share on other sites More sharing options...
Rudeviewer Posted March 7, 2014 Author Share Posted March 7, 2014 I am in so deep I gotta keep boots nearby lol. I've seen them for around 70 usd, just been waiting for my new scope to arrive in a two weeks or so. The artificial star was super easy to make just needed quite the distance to make it work properly. Gotta order some bob's knobs too for both scopes.

Rudeviewer Posted March 27, 2014 Author Share Posted March 27, 2014 Id have to say for the small amount of data I got I think this is the best picture I have produced thus far. No darks still....i tried letting the camera do the noise reduction and it wasn't that noticeable so next time ill try em. The new scope has proven itself already! I can't wait to do some guided subs now. Haven't had enough time to bust out the laptop lately and weather stinks, but its on the up and up.. This was with my Celestron Advanced VX mount and 203mm Orion Newt f/4.9 Link to comment Share on other sites More sharing options...
Rudeviewer Posted March 27, 2014 Author Share Posted March 27, 2014 My trial ran out in pixinsight so I had to process using only Photoshop cs2. I'm used to pixinsight doing most of processing so using PS was interesting Link to comment Share on other sites More sharing options...
