Managed to get ~4h of Oiii on Eta last night and combined it with some Ha and Sii I had done last year and the year before. I've lost the original raw files but found some full res TIFF files and was able to do some basic pixel math in CCD Stack although I can't get the whole dynamic range back. Registered the Oiii in MBJ's excellent Prometheus and did the noise reduction in Startools and final in PS.
