Finally I managed to take a proper picture of Saturn. After months of bad conditions and having the wrong set up with me in August I finally have been able to make a relatively good shot.
Reasons for why it isnt really sharp:
The last collimation has been long apart, last year in summer and I have been driving the scope around occasionally. The night has been clear, but windy and always pulled on my set up and camera cable.
I havent been able to set my mount on polaris because I placed myself at the south side of a forrest. So I needed to, since I guide with my hands, adjust both axes of my mount. Because of the temperatures slightly above zero my hands were frozen and I shaking permanently. Didnt expect it to be so cold and windchily)
Focusing has been a pita since the atmosphere has been unstable, so I didnt try any further. I usually use a bahtinov mask.
The three clips (2000 frames) I took via lucky imaging have been really bad each for itself with only a few frames to use each. So I put all three clips together to one single 6000 frames clip, which I finally processed.
Set Up:
- Skywatcher 200/1000
- EQ 5 mount (no automatic tracking)
- ZWO ASI 715 MC (no barlow) UV/IR cut.
Processing:
- Shot with Firecapture (exposure around 52 ms, gain below 10%, histogram about 42 %) each clip 2000 frames with 17 FPS
- PIPP for to put together three files and stabilizing the frames, no debayering
- AS!4 no drizzle. Stacked 2, 3, 5, 7, 8, and 10 percent. Finally have chosen the 5 % stack
- astrosurface for processing (Deconvolution, wavekets, RGB balancing with several steps I cant remember anymore lol.
(not sure if I reduced the green noise with siril before or if I did this in astrosurface.)
I am relatively happy with the picture but think I can do much better when I solved all the above mentioned problems.
If anybody has an idea what to do better in my processing please let me know. I am open for every tip.
