Saturn 4-25-2015

[phileefan]

Good morning all,

Here is my latest offering of Saturn. Transparency was average and seeing was 2/5. If those two items weren't bad enough, at the time of capture Saturn was at its max elevation of 30 degrees. 3 minute videos processed with AS!2, Registax, PS and derotation with WinJUPOS. Comments welcome. Thank you.......

For all the conditions were conspiring against you, I wish I could get images of Saturn 1/10 as good as that one ...

Hello!
I know what is to photograph with low planet, suffered a lot with Jupiter this season, and that he was about 15 higher than its catch Saturn.
I think you used a 11 "Celestron, and did not use Barlow could have used for so the picture would be most eoof / d of the most suitable system for better resolution. Your CPC 1100 should be f / 10 and must present a better result if high f / 22 with a barlow or Powermate 2X.
It is generally believed that in poor condition of seeing should not employ an exaggerated increase, but this fact in planetary photography is a mistake.
The system always performs better if you use the most appropriate focal length for the type of photo you are doing this.

Thanks for your response. I was using a Powermate 2.5x for this capture. I'm new to plantary astrophotography, but what I've read about the ZWO ASI120MM camera I shoot with, the prime focal ratio is F/20. I'm @ F/25 with Powermate. Clear skies.......

Well, I did not know what the setup used since you did not say.
In this case you are correct, the focal ratio used is very suitable, only a little strange to the small size of the planet but not Seii if you applied some rezide.
In fact I believe that with your setup you can get a better photo credit and the bad result only the low altitude of the star and bad seeing.
Discouraged Not sure what the best records will come!

Nicely done some good detail showing. Saturn is a pretty tough target even more so than last year.

Nice work!
