Finally stacked my last series of pics and layered.
This is made with about 150 images and 7 different exposure lengths.
All done with the Skywatcher ED80 and a modded Canon 40D.
The guidescope is a finderscope with a QHY5 that drives the mount in ST4 mode.
Exposures range from 15 Seconds to 20 Minutes.
All stacked with DSS and processed with CS4.
After a certain amount of pictures there is no gain in making the picture any better.
Will have to use an HA filter next year for this (Looks like M42 will drown in the red dust that surrounds it then).
As always, comments are appreciated (positive AND negative) also tips are welcome.
