No AO, just a converted finderscope and QHY5L2 as the guider. Processing was drizzle 2x followed by deconvolution on linear data with (PI derived) synthetic star PSF. then stretching and a little bit of local wavelet sharpening and noise reduction. Stars were in pretty good shape, but the combination of drizzle and deconvolution produced minor artefacts at the edges of the brightest ones, so they were tidied up in StarTools - hence the perfect roundness. Then image was downsized 0.75 and cropped from 13.5mp to 7.1mp for composition and to remove regions where minor setup changes had led to poor overlap.

Thanks for that Ray. I thought as much. A truly inspiring image. Shows what stock equipment can do in the right hands.
