Hello Dennis,
I guess I just need to drag out the "image processing" manual and try to decipher it, again.....for the 10th time. It is written in Chinese. I have read a lot of poorly written software manuals over the years, but this one takes the cake. I have a solution to crime. Instead of prison, make offenders read the Meade manual through and implement the so-called instructions. Cruel and unusual punishment. Crime would drop immediately.
Seriously, it's probably at least partly my fault. I have a genetic allergy to reading instructions.
Yes, my scope (NexStar 4se) has a wedge, but I didn't have much better results with it roughly polar aligned. There is no fine adjustment......so drift aligning is all but impossible. I still see a CG5 in my future, but the funds just arent available at present (2 kids in college....tight budgets, etc). Sometimes when I take the time to tweek the hand controller very carefully, I can actually get as many as 50 x 15 sec subs. I got a pretty good image of M33 by taking 18 sequences....... finally on the 18th try, I got almost 8 minutes of data with round stars. The final image came out pretty good, but the data was captured from a very transparent, dark sky location......not my driveway (I might as well be in a shopping center parking lot). There is some luck involved too.
I am imaging with a 80mm Orion short tube refractor (to gain a wider field) on the NexStar 4se mount.
When I shoot with the DSI, I have it set on "Normal" mode......so the software combines the frames into 4 images: L, R G, & B. I realize thats not the perfect way to do it.
Let me carefully go through the manual again, and work through some processing exercises. I will probably have some questions for you.
