Saturn. Jupiter and Mars, 8/9 Oct

[symmetal]

Saturn taken as it crossed the Meridian. The scope had been outside for a few hours but the collimation check was boiling quite a bit, so not at it's best.

10" LX200 GPS, 2x Powermate, Zwo ADC, ASI224MC, 4mS exp, 120 sec video,  240 fps.  Best 10% stacked in AS3, Registax and PS. Not great I admit.

Jupiter taken about an hour before it crossed the Meridian. I took some at the Meridian as the red spot was emerging but these are not as sharp as the earlier ones unfortunately. I did recheck the ADC and focus but I'm obviously not got enough. 😟 5mS exp, 2 min video, 200 fps. 20% stack in AS3, Rest as above. Result not as good as others have posted. I did try videos at 4, 3, 2 and 1ms but the 3 and below were very progressively more noisy and couldn't take much processing. The 4mS looked the same as 5mS so I'll likely stick to 5mS from now on.

I didn't fancy staying up to 5am for Mars to cross the Meridian so I took a video at 23:30pm  which was terrible, and another couple at 01:45am when it was higher, and was surprised at how much better these were when I checked them the next day. I did do another collimation check and it was much more steady now.

4mS exp, 120 sec video, 240 fps. Best 10% stack, Rest as above. I'm quite pleased with this one. 😊

All nice captures Alan. But that mars is a cracker. Sinus Meridiani clearly visible.

Nice work. Mars is a beaut, best I’ve seen so far I think

I have to agree with  Neil and Craig, that Mars image is a stunner, Alan , well done !

Ver nice set of images. Saturn looks good with the cassini division under recent UK skies. Mars awesome as well.

I like that Mars! 

Quick questions for the Mars gurus: what's the whitish stuff in the north (icy haze?) and the bright yellow swirl in the south (dust storm?)?

@neil phillips, @CraigT82, @Saganite, @Kon Thanks for your kind words. 😊

The stacked image of Mars didn't look all that special and i was very surprised when I just applied a saved heavy process in Registax and everything appeared. Here's the stacked tif if anyone would like a try.

I was disappointed with how Jupiter turned out. I've just restacked them with different percentages so will have another go.

Scopes out tonight for another try, but not sure if the clouds will cooperate.

I did a little with the image in RegiStax 6...  I think yours is better and doesn't have a blue border round it.

I like yours too Ian. I wasn't sure what colour to go for, though you've made the southern pole, if the bottom is the south, more white which may be correct. Not sure why the opposite pole is blue though, like in mine, though looking at some other images that area does have a blue tint sometimes. The blue border is an Autostakkert artifact I suspect. I should have cropped it off before posting it.

Lovely set of images Alan. I agree with others, the Mars is excellent, but Saturn and Jupiter are none too shabby either.

[symmetal]

@geoflewis, Thanks Geof. 🙂 The following day there was clearish sky after dark and I tried Saturn and Jupiter again but seeing was unstable and it got more hazy as the night wore on so I gave up.
