Please join me in congratulating DSLR & Digital Camera Astro Imaging & Processing's Finalist - honza.ho!
This is my latest photo - 35Mpx mosaic of Eta Cygni region in constellation Cygnus. 3rd bigger photo I took since 2008. Its 4 frame mosaic which contains 20 hours of H-alpha data and 12 hours of color, all combined together to create this multicolor image. It would be impossible to create this image without h-alpha filter. There is so many stars that all emission regions are hidden behind them.
Info:
Optics: Takahashi FSQ85ED, 450mm/F5
Camera: Canon EOS 400Dmod.
Mount: HEQ5
Filters: 7nm Baader H-alpha, Astronomic CLS
Exposure: 20 hours of H-alpha (4 fields, each +-5 hours), 12 hours of color (4 field, 3 hours each)
Processing: calibration in DSS/MaximDL, registration in Registar, stitching together, matching the colors - Adobe Photoshop)
Date: 2/2 of April and May (all clear nights)
Location: town: Cerveny Kostelec, state: Czech Republic, and you should know: Central Europe
