Vast Improvement
<HR style="COLOR: #ffffff" SIZE=1><!-- / icon and title --><!-- message -->Thanks to all I have been able to improve my image capture and processing techniques. I shot this image of Jupiter on Thursday Morning quite late at 06.30.

Details

3 x 40 sec AVI's at 10fps, 2x barlow

Binked, ppmcentred, 990 frames processed in Registax

I'm not sure why this uploadedimage is so pixalated as it isnt in my saved file. Think I need a decent image processing package to resize with.

Nice work Muddy :thumbsup:

The great red spot really standsout in this one. I can see a little colour misalignment you can easy fix in registax. In the wavelets select the RGB align tab on the right edge and push the estimate button. The red fringe on one side and blue on opposite should be sorted by that.

cheers,

well done muddy, as rob says, a colour alignment will help, plus also do you mind posting a few at normal size and say with some different wavelets.

must be pretty stoked.

you are officially allowed a strut around the house for this one.

Robert. Great fix. I wondered how to get rid of the blue ringing. I've got other pics of saturn i must now apply this to. Sample fixed up in 1st attachment below. Great tip.

DP. Sure, no worries. What did you have in mind? Extremes or any particular wavelet adjustment. I guess you need to know what I've done too eh?
I've posted my un processed shot here in the case that I don't provide what you were after. (2nd image).

Strut DP! I've had my chest out since Thursday. I actuallt took a look at the Nexstar 4 Yahoo site to check out Stephan Poirer (Spelling) shots as he seems to be about the best there in imaging with my scope and I reckon this is up with him. I dont expect to be able to achieve much more detail with it but you're right I'm stoked. Thankis for all the help guys.

Nice shot MD.

He's another hint you might like to try. See how the center is getting burnt out? If it's not like that after your stack (and before waveletting), use the histogram on the waveletting page to adjust your tonal levels. If you're still having problems drop the contrast down and retry it. Also try turning off the histostretch on the Stacking???? page before stacking.

See how that goes.

thanks muddy, i can get a feel for the seeing / collimation of your setup with the unprocessed.

This unprocessed one tells me that the seeing was not great
stick at it and make sure you scope has cooled overnight.

Here is dennis 4th Feb jupiter, first image is a frame from the video and the second is a stack of 50, no wavelets.

keeping working on making sure the scope is cooled and that your collimation is spot on . that way when the conditions are like what Dennis had, then you can get data like this to play with.
