Saturn 10th Jan

[Freddie]

Taken 6am ish this morning. Usual setup of DMK21, RGB 5min AVI per colour.

Some strange things going on with the colours in the rings but at the low alt it's difficult to keep everything under control and then get good RGB alignment.

Remarkably good image considering how low it is!

Very nice shot of the planet, Looks as if you have picked up a bit of abberation from it being low, the same happen in an eyepiece.

Great shot Freddie its going to be tricky this showing, nice to see the rings opening out!

[Freddie]

Thanks guys. I only get about an hour to capture once it comes out from behind the trees so was lucky to get some half decent AVIs.

Good to see our old friend again

Nice one Freddie. I think the colour issues may be due to the atmospheric dispersion being at such a low elevation, nevertheless still a good image considering and you can still make out the polar hex!!

Good effort Freddie I find colour noise reduction in image analyser works well on these.

[michael.h.f.wilkinson]

Very nice indeed

[Freddie]

Thanks for your comments.

Pete, you are right, the low alt means that you can get slight differences in the individual colour images and then when put into WinJupos it can be difficult to get perfect alignment even with lots of adjusting. Unlike for Jupiter, there is only the manual alignment option for Saturn (and Mars for that matter) in WinJupos. Like you say, pleased to have got some surface detail though.

[Freddie]

A slightly softer reprocess. Not sure it's much (if any) of an improvement though!!

[roytraveller]

Nice images Freddie. I agree with you on the second image.

Thanks Roy. Wow you dug that out the archive, maybe it stood out amongst all these Jup shots.

[Virgoman]

Yep Freddie damn fine effort at nabbing Saturn so early. Ring are opening out - just a pity it is going to be low here and getting lower.

Thanks Ralf. I was quite happy with it given the alt, got lucky with the conditions that morning. Reprocess was rubbish though!!

Yes, at low elevations this can be a pita...with the Saturn I posted here recently I had 3 consecutive rgb sets but ended up only using one because WinJupos created an image with the same problem that you had seen best in the first image here at the top, where the ring meet the disk at top left (ie, opposite shadow side...)

You end up with a pronounced demarcation "line" there and although it can be ameliorated in WJ the only way to deal with it is in P/shop or something similar...I couldn't be bothered doing that in the circumstances personally!

Yes, good effort Freddie considering it's altitude! 

[Freddie]

Thanks Barv. I'll have to get out again soon as it should be a little larger and a little higher now.

Good effort.  I'm inclined to agree that atmospheric dispersion is to blame for the colour issues.

Thanks James.
