M16 Eagle in H-a
http://home.att.net/~dpersyk/new.htm
The image was taken with a Takahashi E-160 (f/3.3) astrograph aboard an AP-1200GTO. The camera was an SXV-H9, and the exposure was 8 x 15 minutes via a 6 nm FWHM H-a filter. Guiding with an MX-716 and NP-101. There was a full moon and considerable glow from sunset, but light pollution has no affect whatsoever on a narrow-band H-a filter.
I’ve posted both a straight gray-scale image and a colorized version. I gretly appreciate your comments on which you like and why.
Thank you for visiting my site.
Clear skies,
