Jupiter from Cattle Point on Friday, 23 July 21, at an elevation of 28 degrees above the horizon.

I have struggled to get some decent detail from Jupiter, but I feel like I'm making progress with this image.
Almost no wind and at least average seeing conditions on this evening.

Taken with the Meade 12" LX200GPS SCT, a ZWO Atmospheric Dispersion Corrector, a Baader UV/IR cut filter, an ES 3X focal extender and the ZWO ASI174MC (exp. 8.93 ms, gain 300) with SharpCap Pro.
This is the best 30% of 16180 frames. Processed in AS!3, Registax, Astra Image, and PSE.

Any advice on how to improve on this image would be most helpful.

 

Thank you.

Ken

That's a really nice Jupiter pic! Have you ever tried starting with deconvolution and then using a gentle wavelet sharpening afterwards? I think it was moonwatching ferret who got me hooked on deconvolution a while back and I found that my Jupiter and Saturn images came out much better that way. I use Fitswork4 for the deconvolution and then just a gentle tap on the wavelets in Registax6.

Thank you for your kind comments, Matt.

I too am an adherent of the deconvolution. It is the next step I perform after stacking and RGB balance in Registax.

I don't use wavelets anymore (sorry). I deconvolve and then use sharpening. I found wavelets were giving me a harsh look that I didn't care for. I'm sure it was operator error. On my next image, I will try a "gentle tap" on wavelets. AstraImage is my weapon of choice. I like its control over levels of tool functions.

Ken i think this looks great. The processing doesnt look too harsh; colors look great. I feel like this is about as good as it gets without better seeing and a higher altitude. I wish I could stay up late enough to image at 28 degrees but i need my sleep for work the next day. I may try staying up a little later tonight knowing there's just one more work day before the weekend laugh.gif

Thank you, tboss, for the kind words.

I hear you about staying up late on a school night. 5:20 AM seems to be coming earlier every year....
