Open Cluster

M45, the Pleiades from Tierra Del Sol

Got to spend four wonderful nights at my clubs dark site over Thanksgiving break. My main target was NGC2710 but I had to shoot something each night while waiting for the target to rise so why not go for M45 (its been awhile!).

This was shot over four nights and I changed the angle at some point which explains the odd diffraction spikes.
