Jupiter 6th November 23

[knobby]

Hi all, here is my effort from last night. I took 18 runs through very variable seeing from around 9.30 to 10.30 hoping to catch Io and GRS.

This one is the best of the bunch (so far) 10.28 pm.

This is probably the best I've ever managed from my back garden, hope you like it.

3 minutes @ 170 fps approx 30000 frames, best 800 stacked in AS3, tried wavelets in Registax and Astrosurface - preferred result in Astrosurface - tweaked colour and saturation in photoshop mobile.

C9.25 - ZWO 224mc - ADC - 1.6 x barlow works out to F16.

 

Thanks for looking.

Nice image and some details coming through. Very similar to what I had last night with our beautiful seeing😀

The image could do with more denoise in AS otherwise nice processing.

That looks a very good image! There is some pixelation which is spoiling the detail especially around the GRS. Possibly something in the processing has caused this. I would try stacking more frames. 800 is not many.You need to stack at least 10% preferably 25%.

Cheers gents, I've been into planetary for about 8 years but with some large gaps. So much to learn and relearn 🙂

I will be trying to process the other runs later but 'work' gets in the way.

very nicely imaged

About the noise / artifacts It looks fine on my phone, I suspect it's jpeg compression of some sort.

I tried saving as a PNG but it looks very different now 😀

Processing really is a dark art !

That's a very nice image - the original that is, not sure what happened with the png version, but that looks over processed almost like you accidently reapplied the wavelets to the original....
