How I am fighting differential flexure!

Differential flexure can occur when one part of the imaging system shifts slightly such as when a focuser (either on the guide scope or imaging scope) sags. The goal to beat this is to 1) use an Off Axis Guider or 2) make sure all parts of the guide scope (including camera) and imaging scope (with camera) is as rigid as possible and "moves" as a complete unit.

I added tube rings to the focuser and one on the autoguider to limit flexure at the focuser on the 80mm Short tube. So far so…

Check out this 3D image!!!!

Check out Finnish astrophotographer, J-P Metsavainio, latest 3D image.

Universe Today has a great write up on him. It's pretty amazing what he does.

Post a picture of your first AstroPhoto image...EVER!!!!!

Ok here goes. We all started out as "noobs", wet behind the ears and wondering if this hobby is something worth getting into. There have been many "A-Ha!!!" moments and a lot of "$%@# er" moments. I think I speak for all of us, though, that we have learned quite a bit over the years (anyone remember CelestronLife?) and that we need to look back at the progress made. I'd like to share (and others to join in) my first images taken through a telescope. It was a SkyWatcher 8 inch SCT, UNGUIDED,…

Countdown to last Space Shuttle launch

I just want to share this website with all of you space enthusiast! The images he has captured of past launches are stunning. I hope you all enjoy! Feel free to write about any experiences you may have had? Have you seen a launch or been to KSC?
