Description

This is an attempt to give depth to the image and turn the residual noise into something nice by using GIMP bump map filter. The original is the result of ~3800 15" shots taken over a few nights in January with the Celestron 130EQ and the Svbony 305. The object barely fits in the FOV, so you can imagine it took some frequent adjustment with the limited tracking capability of the EQ3 mount.
