Finally got my DIY electronic focusing kit to work ok with SGP for auto focus. It's not perfect, but since my gear is 350m away from the house and the Esprit needs very regular refocusing (after every frame would be best), it seems like an ok compromise. FWHM was in the low 2's for all of the frames, with the worst being ~2.5. Doing it manually I can get down ti 1.7ish on a good night.
Anyway, this is my latest work, a mere 7.8hrs on the Antlia galaxy cluster. Not very often imaged, I thought I'd give it a crack, albeit with micro data compared to Rolf's epic 152hr integration.
