      Description

      In cooperation with Marcel Drechsler.

      Marcels frames:

      9,5 h Ha

      7,5 h OIII

      1,0 h Luminance

      Scope: 11" Celestron RASA (Rowe Ackermann Schmidt Astrograph)

      Cam: ASI 1600 MMC

      I processed frames from Marcels 11" RASA together with such from my 10" newtonian and my Takahashi Epsilon 130 D. It was hard work, but a lot of fun at the end.
