היו אתמול תנאים כמעט מושלמים. שקיפות מעולה, וממש טוב לראות.

הסתכלתי על הגדלות של 400+ עם הדובסוניאן שלי, אז לא יכולתי לוותר על לכידת ענקי הגז.

 

ציוד: דובסוניאן ידני 8 אינץ', asi482mc, X6 barlow, מסנן uv/ir cut.

pipp - autoStakkert - astroSurface - gimp

You've captured some nice details there, but they do look a tad too contrasty and over-processed. I wonder what would happen if you backed it off a bit?

This is before GIMP. I prefer the result after.

Got the raw stacks? Others here can show you examples of less processed results that look natural. There's no doubt you've got excellent captures there.

Looks like great raw data! Keep trying with the processing, you'll get it.

Here is the stack file after AS, and another attempt at processing. Better?

Sorry, I can't read your language, but i see you posted the raw stack. There are much more experienced people than me here who may show you how to make the most of it but I prefer it looking something like this from your data:

It's important to recognise that there is no right or wrong and how you wish your images to look is a personal thing, so if you prefer it more heavily processed then that's perfectly fine.

Yes, this looks very good.

 

Your initial images were way over-sharpened and are swamped by ringing artifacts (e.g., look at the Saturn's shadow on the rings; the black area is bordered by a bright strip).

Ok, I tried to download wavelets also on Saturn.

That's why I drizzle my images, it prevents me from overcooking my images and it happened to me just now when trying to process this fine data.
