      Description

      This deep field and HR image was taken with the 1m C2PU telescope in june, using a QHY600 camera. S. Brunier and David Vernet sent the data to me for processing.

      I have rarely seen such a resolution. The stretched stack shows faint objects of mag 25,3.

      Luminance : 13 hours (784 x 60 s)

      R : 2 hours (126x60s)

      V : 2 hours (115x60s)

      B : 2 hours (117x60s)

      IMO this is one of the best images of this object ever taken from the ground (Pro or amator). For example here is one from the Kitt Peak 4m (credits on the site) :

      Hope you like it.

      Title: BXT trie for the fat and medium stars

      Description: I tried BXT from the beginning to see if it is better. The fat and medium stars are. But I find my conventionnal pipeline better for the rest. Enjoy.
