I took a Jupter shot a few months ago at prime focus with the scope, but couldn't really get any details in the atmosphere. Took the scope out tonight, the battery died on me within 10 minutes (odd, since I fully charged it last week, and haven't used it since then). I was a bit upset to say the least...so, I had a crack at the moon manually, managed to get a few shots, but nothing grand (will post later on tomorrow evening when I've processed them). After the moon, I gave Jupiter a shot - and this is the result. Using a eyepiece projection tube (looks like a barlow, and the eyepiece sits in the tube itself and gets locked down with a thumbscrew), which connects to a t piece that connects to the camera. GSO 15mm plossl used to get this image, and this is a 200% crop. I had a hard enough time getting this shot, I'm scared of using the 4mm lol! Lots of fringing, I'm not sure if this is a result of collimation issues (which is what I suspect), or possibly a slight mis alignment with the eyepiece holder perhaps? Or simply, poor optics in the Equinox unit.

Still, I can see the 2 main equatorial bands, so I'm pretty chuffed...

Hi David,

You are definitely on the way, you will benefit using registax to align the colour channels and doing some other processing, there is a fantastic article here that Mike Salway did on Planetary processing etc.

For example, I ran your image through Registax and aligned the RGB channels to remove the Chromatic abberation showing, I couldnt do much else with the 95kb JPG, but you can see the difference already.

Keep it up.

Cheers

Chris

wow oh wow, that *does* make a HUGE difference. Sweet! Must check tutorial out! Wow. Remember, this is only a single shot. I know a proper webcam etc would be better, but this was a half hearted attempt by me last night (and the battery powering the mount had died, so I was aligning manually).

Well done both eq. belts - much more detail than my first attempt. Mikes article is great for planet imaging alright.

Not sure how I missed your reply Dave - thanks! I think it was more luck on my part than anything. I could see the belts (faintly) through the viewfinder, but wasn't sure if they'd appear up on the image.

I forgot to check out Mike's tutorial, must find!
