NGC 891 Edge On Galaxy

Air-cooled Olympus C2000Z Digital Camera - 20" GOTO Starmaster Telescope

by Gary Honis

 

Ambient temperature was 24 degrees Fahrenheit which allowed low noise imaging with the air-cooled Olympus C2000Z digital camera. 21 images of 32 second exposures each were stacked for these images. Skies were partly cloudy with windy conditions which made imaging with a 20 inch Starmaster in Dobsonian's hole (near Zenith) a challenge. I will image this galaxy again under better conditions and expect to get better results.

This image was salvaged from the first test image taken with a 31mm Nagler and the Televue digital camera adapter that can be seen HERE. (Unprocessed)

A stack of 11 of the better individual 32 second images:
