Hi
I want to share with you this image in HaRGB of M17, the Swan or Omega Nebula taken from Bogotá Colombia.
It was taken with a modified Canon T1i and a hyperstar lens at f2.3 with a C925 EdgeHD telescope on an iEQ45 mount. Exposure time was 4.5 hours (2 hr RGB and 2.5 hr Ha). Here it is:
Captured with Backyard EOS and processed with Pixinsight.
Thank for looking!
Best regards
Alfredo
