Fantastic image, Pete. Is this a derotation? If you have time to give some quick details about your capture routine, it would be appreciated.
Thank for the compliments, Kevin. I do not derotate. I haven't really played around with WinJUPOS a lot. Capture routine goes like this. First the basics, collimation check, thermal stabilization, etc. I have a permanent setup so that's pretty easy. Focus on the R channel. That's where most of the image detail comes from. Easy to do when the seeing is good, not so easy when the seeing poor. I focus directly on the planet and nothing else. Motorized focuser is a must. When I have the focus perfect on the R channel, I check the other channels. I have a motorized filter wheel, so it's easy. I do 3 minute captures on R and G each and 4 minutes on B. I usually try to keep the gain around the middle. High gain means high noise. With good transparency, I use 4ms shutters on R and G and 7.5ms on B. I use as small of an ROI as possible to allow for the highest frame rates. During capture make sure you never saturate the histogram. I save files as 8 bit SER. So that's pretty much it for the capture.
The next step is to back up all the raw data before processing. Some may think this step is unnecessary, until they lose their raw data for some reason.
I use Autostakket 3 for alignment and stacking. I will use a single alignment point to initially sort through the gigabytes of data. If something looks good I will try to use multiple alignment points to extract more detail. Depending on seeing, I will stack anywhere from 2% to 75% of the frames.
I process each channel individually. Then I do an initial sharpen and de-noise in Registax. Save file. Go to Astra-Image for deconvolution. I only use Lucy-Richardson. Gaussian point spread function, small for good seeing, large for poor seeing. Save file.
Then I go to Photoshop and for each channel I do rind and halo removal. I also do some high pass overlay filtering to extract additional detail. Then finally I combine each channel to a color image. I manually align the channels. Adjust color and brightness. Then for Mars, I usually finish with a R channel high pass overlay.
