hi Bert
Thanks for posting such a clear demonstration of the benefits of super-resolution reconstruction through dithering. Its a great way to increase the flexibility of a system isn't it? - if the seeing is poor, process normally, if the seeing is good, use super-res to increase the image scale (by 2 say) and increase the number of subs (eg by 4x). All without changing the system at all - its sort of like having a "resolution" switch on the side of the camera. I guess you could get the same flexibility by binning images from a larger camera in poor seeing, but then you would have to buy the larger camera in the first place. The only problem I have found is that the tracking mount need to be pretty good - super-res very effectively enhances trailed images and I have ended up with long, thin stars instead of eggs at times. BTW, I use Nebulosity, which automates the process, linking to PHD to do random dither between subs. Sorry about the long-winded post, but this is a fascinating subject.
