Hi, don’t know which format you like to have images, so I decided to send a
JPG file

April 29th, 2017, 21:00 TU

Stacked Image 5*120s Luminance (C), STL 11000M, 1240/5150mm, bin=1
(18mue-pixel), IAU Observatory Code 239

 

I don’t support the low brightness results. – Even that I’ve not done a
detailed analysis, I would estimate the brightness in the Range of 16.0 ~
16.5 comparing to objects outside of M63 – This is maybe driven to the fact
the Aperture Photometry fails doing measurements within a galaxy.

 



 

 

 

Best Regards

Georg M. Piehler
