Saturn 18/19th April

[Helen]

Here's my first go at Saturn tonight.  I'm quite pleased as I've never managed to get any planet colour before - although its still rather subtle!  Saturn is low, so I'm having to use higher gain and gamma than I would ideally like to keep the exposure times in check and this is causing high noise levels.  Maybe as it gets higher I can turn things down a bit

The dmk would be better in keeping down noise levels, Saturn only reaches about 20degs max so very difficult!

[Helen]

Yes, I think I need to learn to do RGB....

Here's another one with slightly different processing...

Good effort, Saturn is very tricky at this low altitude.

excellent image scale and definitely captured some colour!!! Saturn is pretty tough at the moment. i captured it last night at around F10 so the image scale is smaller but hopefully i might have a slightly sharper image though probably not  

it just seems because Saturn is quite dim everything has to be set to high, resulting in a noisy image unforntunately.

[Helen]

Thanks    Yes, I think smaller would have been sharper, so less barlow next time :wink;  And I probably need to get better collimation (although I fear fiddling in case I make what seems not too bad worse!)

Was fun last night though

V nice.

[Helen]

 A bit more playing and a reduction in scale

I think I'll start from scratch again tomorrow with As2 and see whether there is anything else I can get out of the data.  And I'll do some at lower mag next time out

Yeah, AS2 tends to give me better Saturn results I notice.  Deconvolution is also very effective.

very cool i love Saturn such a great gas planet to image

That's impressive for the altitude.

A good effort.  It certainly is tricky at the moment.
