Data from early March 2023 on my recently sold FSQ-106EDX4 testing F/3 0.6x reducer on M101 with QHY268M (36mm Chroma LRGB). About 3.5 hours of 180s LRGB exposures (32, 16, 16, 8). Lost 8 blue at end of session due to target setting behind trees. A bit of green halo on a few stars (shift with faster F/3 on filters or because green master had higher FWHM on stars than L, R or B).
