Jupiter 30th July @330am

[Kon]

My other target last night was Jupiter. I think this is my best effort so far with this gas giant. 8" Dob, manual tracking, asi462mc, 2x barlow, UV/IR cut filter. PIPP, Autostakkert, Registax and Gimp. I have more captures to go through slowly but these two captures were the best. I think I can improve the processing.

looking like theres some nice detail coming through, maybe a slight upscale might help reveal even more!

[neil phillips]

Your levels are looking healthier. Maybe the extra contrast with jupiter more in a dark sky. Some good detail and colour. Do you know what sampling rate your at ?

Agree with Simon upscaling might be worth a try.

@si@niteand @neil phillips thanks both for the suggestions. Bare with my ignorance but upscaling, does it mean use drizzle or just increase the size ?

Neil, I will look up the value when I am back later and report.

I feel I should be able to pull some more details. Rainy weather tomorrow, so I can rework them .

I think you could be using a 3x barlow with your dob. Aiming for around F15. You may be a tad under sampled. At 2x. Though i do realize this causes more problems undriven of course. A basic drive would really bring a lot to the table. 

Yes try a 1.5x drizzle. it will weaken the wavelet sharpening. But you just adapt to it

Is that a storm above the GRS to the left?

According to this calculator I am over sampling. I have a 2.5x powermate but clouds rolled in before i had a chance to test it.

This is a combination of 1.5x drizzle and using a combination of deconvolution in Astrosurface and wavelets in Registax. I think it looks better but happy for your feedback, good or bad..

I think both are storms as the GRS was not in view at this time this morning.

Well what do you think? looks a lot better to me. i can see the detail better by a long shot. Drizzle will sort out some of the under sampling. But better to do it with a 3x barlow. But maybe not undriven. As it causes other problems. 

[neil phillips]

Apologies for some reason I thought you was using the 224 mc

F15 for your setup i think. Not sure i would trust 

I will try next time.

See above i thought you was using the 224. scrub that

I agree it is a lot better. There is the other one. I have a few more captures to go through so maybe seeing might be better in the others. PS still looking into the EQ platform. Thanks for the tips on the processing.

As far as sampling goes with the 462 c at F5 your slightly under sampled not by a lot though. I would aim for F11 or F12 

A small extension on the barlow would get you there

BTW from the drizzles first one looks best to me. less over done with contrast and bloating

Yes I agree, a bit too much; at first it looked good in my eyes.

@neil phillipsI reprocessed the last image in a less complicated way and I think it has a more natural feeling to it.

Yes i like them Kon. I think the drizzle is working well. Your experimenting too. Which teaches the eye. Mistakes are also good. As it teaches what we dont want.
