Hello every body,
So in 2011, I done some shot in Ha on this PN Abell 21 with my refractor TSA 120 and the 314L+ but I never got it in colour so during the night of February 14th, I have done some shots in OIII. Yesterday, I was surprised and very happy to get good result about my image because I did the processing with my old ha sub and the OIII sub. Now the result in RGB with 9 x 900s in Ha + 7 x 900s in OIII: http://img197.imageshack.us/img197/8...21rvb1cs53.png
