Saturn animation

[multiweb]

I did a animated GIF of 13 x 5min loop stacks on Saturn at: http://www.astropic.net/astro/saturn_anim.gif. Problem is that I don't see much spinning going on. :shrug:

Questions. Did I go a little too hard on the processing or there's not much details (that's an IR filter) to see because of seeing, possibly focus? :question:

I've attached one still as well to check.

Thanks for any tips. :thumbsup:

Hi Marc

Looks good to me, I can't see any issues with focus.:)

I think you are always at the mercy of the seeing conditions for these high resolution images and animations.

I think there are fewer distinct features on Saturn, so rotational movement is more challenging to perceive, even though it is similar to that of Jupiter, some 9 or 10 hours.

Great shots, I'd be very happy with those results.:thumbsup::thumbsup:

Cheers

Yeah... it was disappointing. I wonder if 5min is too long for saturn. I'll try harder with the focus and tracking. Even the inner and outer rings are not separating as clearly as the shots I see online. :shrug:

Quick question on AS!3. The way it ranks subs. On a good run I might typically get half the subs above the 50% line. One particular run I had almost all close to 80% then a sharp drop at the end so was able to stack the majority of frames. So does it rank subs relative to each other or does it have a "gold" standard to grade against (like a FWHM for deepsky). I mean if I get close to 90% on a run it could be that I have 90% average and 10% extremely bad ones right? It's not an indication of the quality of the run. :question:

Hi Marc

I can't really answer your question, as I haven't plumbed the technical depths of AS3!.:)

I just assumed it measure the average of your particular batch of frames and then used that average to determine those above or below the line?:shrug:

You're correct. I'm just watching this video that has a lot of really good info.
