My final image for this season, the sunflower galaxy, M63.
This is an LRGB image taken with the MN190 during March and April.
There were/are a lot of issues with this image. Collimation of the MN is still off, wich resulted in weird star shapes. The addition of an oag to the imaging train caused the focuser to sag a bit. In the end I guided the L exposures with my finder guider.
The AZ-EQ6 needs some tlc this summer. Earlier I found some debris from the belts in the housing. RA guiding showed higher RMS than DEC.
Description: The original image looks too dark on my tablet, but ok on my laptop. So here's a slightly lighter version.
