M3 - Globular Cluster


M3 Cluster

Another Globular Cluster, shot low in the sky

Magnitude: 7.0
Location: Canes Venatici (Hunting Dogs)
Date: Sept 19/04
Exposures: 43 best of 45
Exposure length: 4 seconds
Amp on setting: OFF
Brightness: 100
Gain: 50

Notes: First try at M3. Focus was a little out, and polar alignment was significantly off, as 4-second exposures show drift. Exposure time seems like a good starting point, but 3x the number of frames would probably bring out more low magnitude stars.
