I am getting closer. Got my new CGEM II mount. Still waiting on the AVX 8" Newtonian to come in. The 8" will go on the CGEM II and my 130 Meade Newtonian will be on the AVX. 8" for imaging and 130mm for viewing and web cam planetary. Slowly coming together.

Just when I thought I was on my way. I setup Friday afternoon used a white tee shirt too 30 60 sec flat frames @ 1600 iso. They seamed to come out to me. Later that night I set up and tried my best to get my light frames (60 sec @1600 iso) but stopped when I saw how they were coming out. I am hoping you can see what I did wrong. I think it is maybe focus or collimation is out. Let me know if you can help.

Your flat is a little bright. The idea with a flat is to find any areas where you do not get 100% brightness, and there are always some somewhere. Adjust your flat exposure until the entire thing is not one solid color of white. 

As for your lights, yep, that's a problem. How are you focusing? There are two ways most people use when starting out: a mask, or by using live view on a star.

The mask works the best, if you have one.

For a star, turn on your live view, get a bright star right in the center of your frame, zoom in a LOT, and focus until the star is as close to a pinpoint source of light as possible. That will get you pretty dang close to good focus.

Once we are sure that is good, and you still have issues, then we can look at collimation but I would guess your focus is just way off.

@asadmin yes I agree it is the focus. I was rushing things thinking I needed to hurry before Orion was out of my view. I really had plenty of time and didn't need to rush. The other problem was I am using Backyard EOS and hadn't really sat down with it and learned it. I couldn't get live view on my computer or the camera. Me not knowing I needed time to figure it out.

Well Sunday I spent the afternoon with telescope, camera, computer and Backyard EOS. Duh I needed to switch from imaging to focus for the live view to come on. This is a learning curve for me which I will slowdown and not rush it. You know Allan I am alone down here in Corpus and don't have anyone to learn from or coach me. So please bear with me as my style of learning is doing and muscle memory. Thank you for the help it is very much welcomed. Oh so for the flats I did that during the day with it being sunny out. I stretcher the tee-shirt out using rubber bands to hold it in place making sure it was flat(it was doubled a few times). I pointed the scope up and shot. Was that not what I needed to do?

 

Thank You again

Billy
