Big and small Jupiter

[riklaunim]

I was trying to get good image at f/28 last night. Seeing wasn't as good as f/28 would want to, but still 2 out of 4 sets gave good results. At f/28 for ICX098 in DMK I have to use up to 1/19 sec exposures for the IR channel which adds camera noise and makes the seeing affect frames more. It's hard, but next month ICX618 cams should be finally available - QHY IMG0H or Basler Ace

f/28. First is made with wavelets and blur, second with convolution (autostakkert) and less blur:

DSI III Pro, f/10, Jupiter moons, from left Europa, Io, Ganymede, Callisto (click on the thumb):

I've put Jupiter from processed image on strongly waveleted the same image.

Very nice images but how do you find clear skys? Its been 3 weeks since I last had a chance to image!

[riklaunim]

Well, in Poland since few weeks at day 35C in shade, night not lower than 25C (sometimes 20C)

Nice Rik,

I prefer the 2nd f28 as it shows more detail without much extra noise

Great work.......

Aaahhh.....that explains it!

Hi Rik

You are getting some cracking detail along with processing

I'm using a DMK31 with a 2.5 x powermate and a 200mm meade SCT and am at 1/9sec exposure so I'm struggling to get the frame rate also I'm burning out the bright areas and losing detail in the faint

I need more practice

Cheers

It's good to see a DMK21 getting these images, as I have one and am looking to swap my TV Barlow for a TV Powermate soon to hopefully get images likes these - well done.

For DMKs don't go longer than 1/30 sec at 30 FPS mode with max gain. It's do-able at f/20 for IR-RGB and RGB at higher focal ratios. Going to longer exposures makes the images **** due to camera noise and seeing.
