Description

M 51 - Whirlpool Galaxy 

Test night after collimation on the RC8.  Poor seeing. Poor guiding. Breezy.  

Bottom cropped due to misaligned oag prism to camera sensor after collimation. My bad. 

This is 68 180s subs, or a touch over 3 hours of exposure.  RC8 & ASI071MC riding an EQ6r Pro.  Image acquisition via APT and processing in PixInsight.

Description: An updated image of M51 with better collimation on the RC8. Still not perfect, but running out of time to collect data until next season.
