Alignment (including de-rotation), stacking, processing and compositing via Photoshop CS
These deep sky photos were taken with a Meade 12" Starfinder Dobson hot-rodded with a Dob-Driver II tracking system, a 2" motorized NGF focuser and a Meade ETX-90 for tracking. While it is possible to take time exposures up to 3 minutes with this system it is very difficult.
