Flat fielding and calibration is one thing you need to learn to do properly. It is easy to do and will improve your data dramatically so do some reading on it and get into the habit to shoot flat frames for each filter along with bias frames and possibly dark frames depending on the camera you are using. Calibration will take care of vignetting, uneven illumination, hot pixels, sensor defect, dust motes, etc...
Dust is unlikely to move while you're slewing but if you change your camera orientation you'll have to re shoot your flats for each filter. A lightbox or an EL sheet is the easiest way to shoot flats.
For light subs start with 5 or 10min subs. Flats will have to be different length as well depending on the scope used. Read about calibration.
Taking notes about what works is good. That's how you learn. Shoot what you like as many times as you want. It's about you having fun, not about what others think.
Likewise. Have fun!  |
Thank you very much for your answer
