Description

M45 is clearly visible in the DSP Remote all-sky camera feed from @Michael J. Kidd's AstroShed, so imaging this bright asterism and associated nebulosity piqued my interest.  Another motive for imaging M45 was to determine if my 5min broadband subs at f/5 would incur too many saturated pixels.  I was happy to learn that only ~20K pixels of the 65M pixels were saturated, the dynamic range of the Sony IMX455 sensor is quite amazing! 

Large diffraction spikes were inevitable from the bright stars on a Cassegrain OTA.  I found the diffraction spikes on the series of medium brightness stars leading to Alycone and the pinkish nebulosity near Merope pleasant to my eye.
