Not too sure what to think of this one, as it could still use a little work. I keep saying to myself I'll get back to it, but it's been on my desktop untouched since December, so I've given up the ghost.

This image is of the Pleiades (Seven Sisters/M45). You may have seen it as a fuzzy patch of stars that look like a mini-big dipper in the winter southern sky. If I remember correctly this is ~ 3hours of ten minute exposures taken through a 5" Televue refractor with a QSI 583c at some form of negative temperature. Calibrated with dark, flat, and bias frames.

This is a combined image set from January 2013, and (I think) August 2012. The straight line at the top right is from the different noise levels of the two image sets, but I feel the combination was worth it, as the dust plumes at the bottom right and in the centre of the nebula take a fairly deep exposure.
