NGC6979 Pickering's Triangular Wisp & NGC6960 Veil Nebula W

NGC6979 Pickering's Triangular Wisp & NGC6960 Veil Nebula W

Date: July 21, 2008
Location: Victoria Centre Observatory

The Moon was 2 days past full and lit up the high haze in the sky causing severe light pollution (see the blue gradient on the right side of the image). Despite this, I wanted to see what kind of images my new Borg f/4 Astrograph would deliver. This photo is a cropped version of the original, so a large field-of-view is possible with this f/4 Astrograph. I did not have a perfect polar alignment with my HEQ5 Pro, so some slight star trailing is visible when the image is closely examined.

This setup is very easy to use for astrophotography, and I expect to make good use of it, especially while the steady summer weather is with us.
