Jupiter and Saturn under a Full Moon

Haven’t done any planetary imaging this year so decided to capture Jupiter and Saturn after I captured M22 on Wednesday night as conditions were OK. I waited until they were close to the meridian up nice and high overhead and took about 5 or 6 videos each
6”f6 Bintel GSO newt on an EQ6-R Mount
Goto and tracking EQMOD, StellariumScope and Stellarium
Canon 600D with Televue 5 x Powermate
ISO 800
Frame , focus and Capture BYEOS Planetary mode
5 x zoom setting for 1:1 pixel resolution on the Canon
Jupiter 1/50 exposure setting , 30fps , 1500 Avi frames ( 6 video session )
Saturn 1/6 exposure setting , 30fps , 1500 Avi frames ( 5 video session )
Both planets were bobbing around a fair bit but managed to capture enough video to process some sort of image
Stacked in Autostakkert 3
Processed in Registax 6

Cropped and resized both images to 140% so lost sone resolution in the process , should have left them original frame size. Also should have bumped up brightness and contrast a bit too. It’s been over a year since I’ve done and planetary imaging so you have learn all over again !!


Comments welcome

Thanks

Not a bad outcome at all, considering the moon was out.

You should have captured it as well!

That's very good for DSLR but at f30 you'll need exceptional seeing. Have you tried stopping down to around f15 - f20 on average nights? I think a 3x or 4x barlow/powermate will suit the 6 inch better.

Thanks Peter and LIS
The moon doesn’t really affect planetary imaging unless your very close ( unlike DSO imaging )
I’ve tried using the 4 x Powermate on the 6” but you have to bump up your exposure or ISO to achieve some decent resolution. My sweet spot on the Canon is ISO 800 for both DSO and Planetary
Admittedly I only shot 5 or 6 videos. Last year I was capturing 10 or so videos in a planetary session with some really good results ( that’s Lucky imaging )
I’ll be out there again when this horrible weather eventually moves on
Here’s a reprocess of Saturn
Reduced Layer 1 sharpening
Increased Layer 2 and 3 sharpening
Bumped up contrast and brightness a bit
Touched up with a bit of noise reduction
Keep same frame size and resolution

A slight improvement I think ? ( about the best I can squeeze out of the data )

Thanks
