Friday night early Saturday morning, the clouds and fog were quite frustrating but managed to get an image of Jupiter thru my 10" dob.
Imager used was Neximage with 2.5x powermate.
Only managed 10 sec of AVI and even that was ruined by fog moving in half way thru sequence.
Iceman, you comment that make sure you have a full histogram, what are you using to check this ? I did a histogram stretch in regstack and procecessed the RGB channels individually then recombined.
26826

That's your first ever image? That's absolutely fantastic, especially for only 10 seconds of video!!
For the histogram, use k3ccdtools to capture, and in the preview screen you should get a histogram bar in the top left corner, with 0 at the bottom at 255 at the top. You want to set your exposure/gain so that the white bar is above 200.
Your image looks good though - not under or overexposed.
Fantastic work.

Iceman,
Yes thats my first image, I read all the articles on how to do it on this forum and spent some time just observing what the image looks like on the screen and getting the best focus, that 10:1 focuser was a good investment.
Its not that easy getting the planet to drift thru the FOV so with the clouds and fog I only had 1 capture. I am waiting for the tube ring for my EQ6 but Bintel currently are out of stock.
Thanks for the heads up on the Histogram, I wasnt sure what value needed to be on that yellow bar so I just looked at the computer screen and when I was happy with the image brightness I set the camera to those values and left it.
Well done !
For a first image of Jupiter you've pulled a fantastic shot and under difficult conditions too.
Wow for your first image thats a ripper, Great stuff.
My first image was a fuzzy blob.
Cheers
