Join the Online Discussion on Night Sky Photography

April 16 at 1PM (Central Time) Minnesota Public Radio will be hosting an online discussion on Night Sky Photography. I and 2 other photographers will be answering questions from the public. Since I only do "deep space" imaging I don't know how many questions will come my way, but the other 2 people are experienced in (and good at) night sky photography. There's a link to the event on my web site: www.wa-chur-ed.com.

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 processing: how much is too much?

Ok so you guys know I'm new at this. When I first process my photos, I try to squeeze out as much color and detail as possible. Then, I'll go back the next day and it looks totally over-processed. Sometimes almost cartoonish!

So a couple of my questions are these:

How do you know when to stop with the processing?

How do I know when I have achieved accurate colors of what I'm shooting?

I'm currently only using my camera's software to process, which seems to work…

Switching to ACP

CCDap is so unstable. Actually going to try the free program Steve Coates turned us onto tomorrow, but man CCDap is just unstable. When it works it's awesome when it doesn't it blows a night, and it seems to be 50/50. ACP apparently much more stable.

Recommendations for OAG?

I've always used a separate guide scope and like the simplicity that it offers, but I now have pretty clear evidence of differential flexure despite doing everything imaginable to make a solid connection between the 2 scopes. So I want to try an off-axis guider and am looking for recommendations. I think it should be very adjustable (both rotation and prism position) to be able to find a good guide star. My current setup uses 2" SCT threads to connect the reducer/flattener to the scope. This…

Wonder how much it would cost to have your own like 20 inch orbiting telescope.

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,…
