M92, November 5, 2012

It's Bonfire Night for our cousins in the UK.  IN celebration, I took this pic of M92 as an example of celestial fireworks. The image was captured on the 14 inch with a Nikon D40 at H1 (3200 ISO).  The Nikon performed auto noise reduction and the final stack was of nine 30-second exposure (using Deep Sky Stacker). The final image was processed in Windows.  Even though polar alignment was rather rough, the image shows almost no field rotation.
