Description

I captured this image at f10, full frame on my tiny chip in the DSI IIC OSC. Despite the high focal ratio, this grainy image was OK, given a single 10 minute exposure, but would benefit from many more sub frames.

Nevertheless I thought I would see what I could pull out of the grain, using Startools. Looking forward to the next moonless period to really do these galaxies justice.
