Deep Sky Images

Blogged by Xiao Sun on July 1, 2009 and tagged with Sample Images.

It has been a while since we received deep sky images last time. Ralph Ford, based in Redondo Beach, CA, took the following Messier astronomical objects with his DMK 21AU04.AS astronomy camera and sent them to us last month.

Messier 13

Messier 57

I took the enclosed images with a DMK 21AU04.AS camera mounted to a 16″ F/46 telescope. The images were stacked and processed with RegiStax, each frame being a 4 seconds exposure. While the field of view is only 6.5 X 4.9 seconds, the large aperture produces bright images with short exposures.

Thank you Ralph for the nice pictures and the info on them!
