Hi All,
I put together this image from Luminace data i shot in early March with RGB data i shot on Saturday night to make this nice image of the Blackeyed galaxy. The seeing and tranparency were 4/5 on Sat., so i wasnt gonna waste it inspite of a bright moon!
Here is the shooting data:
Scope: Stellarvue SV-102 APO @ f/4.9 w/Celestron .63x focal reducer for the RGB frames and f/7.8 (native FR) for the Luminance frames
Camera: ATIK-2HS
Exposures: 76:49:32:42 240 sec subs for lum 50% gain amp off, 210 sec subs for RGB 70% gain amp off.
Mount: Losmandy G11
Guiding: ST-4 autoguider and SV80/9d guidescope
Filters: Astronomik LRGB Type 2 & IDAS LPS
To process i used Images Plus, Registar, Paintshop Pro 8 and PixInsight's DBE tool to remove the nasty moon gradients (what a great tool).
Thanks for looking!
