Constelação de Norma. Nebulosa bipolar criada com material expelido pela estrela central devido a sua alta rotação. Distante 4 mil anos luz e extensão de 4 mil anos luz também.
Technical note:
I did 62 photos:
26 x 150 sec - ISO 1600 - Skyglow filter
10 x 150 sec - ISO 1600 - UHC filter
10 x 150 sec - ISO 1600 - Halfa filter
And on another day:
19 x 300 sec - ISO 1600 - UHC filter
Total of 3 h 30 min.
I had many problems with DSS stacking using group ressource. I did many combinations of files and procedures.
DSS didn't use all UHC and Halfa frames when using bias file. And the result was aberration.
2 days working on this issue... I gave up !
Nevertheless I had two good results with:
1) 15 x 300 sec - ISO 1600 - UHC filter without bias.
2) 19 x 150 sec - ISO 1600 - Skyglow filter + 5 x 150 sec - ISO 1600 UHC filter + 6 x 300 sec - UHC filter (the best FWHM frames for each group)
I can not hide my frustration. 3 hours of data reduced to 1 hour !
First work:
GSO 305 mm - Canon T3 - OAG - Coma Corrector
15 x 300 sec - ISO 1600 - UHC filter without bias.
Second work:
GSO 305 mm - Canon T3 - OAG - Coma Corrector
19 x 150 sec - ISO 1600 - Skyglow filter + 5 x 150 sec - ISO 1600 UHC filter + 6 x 300 sec - UHC filter
nota: uma bela imagem e detalhes da nebulosa pode ser vista em http://panther-observatory.com/gallery/deepsky/doc/NGC6164_F9.htm
