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.
The Great Nebula in Orion, M42
The Dumbell Nebula, M27
This is a stack of 2 60" exposures at ISO 800. These were the only usable exposures out of 21 shots. The stars were repaired using Keith's Image Stacker.
The Great Globular Cluster in Hercules, M13
This is a masked composite of 1 30" and 1 60" exposure at ISO 400.
These moon pictures were taken through a Meade ETX-125 telescope except for the last one, which uses the 12" Starfinder. They are typically stacks of several images.
