Hi to all.This picture is a stack of 9x4.5min exposures at an ISO of 800.With a Hutech nebula filter.The inherent camera noise was subtracted from each frame in Photoshop before stacking with Registar.Then adjust the usuals in Deepsky image processing.
The Canon 20d and 300mm F2.8L were mounted piggyback on a Saxon 600mm F5 as guidescope with a toucam and guidedog etc. controlling a HEQ5 mount
via a parallel port relay box.
This picture does not do the original any justice as all frames were 25M tifs
derived from raw.
