Can't use Pixel Shift Resolution in B mode

**cheekygeek** · 05-21-2020, 10:16 AM

Some really bad answers in this thread that don't understand all of the other tools out there. "The stars move" is irrelevant if your DSLR is riding piggyback on a telescope that tracks the sky. Similarly, there are tools like the Vixen Polarie which compensate for the turning of the earth or (for the DIYers out there) you can even construct a "barndoor drive" (also called Tangent Drives) that will serve as a platform for the camera and will compensate for the turning of the earth (the APPARENT movement of the stars).

Also Pixel Shift Resolution will work for exposures up to 30 seconds (to get full benefit you must shoot in RAW mode only (Not RAW+ or JPEG). This would result in four 30 second exposures being made, which would be combined in post-processing to achieve the full benefit (and the equivalent of a 2 minute exposure). I have yet to see anyone trying this with astrophotography, but I have a hard time believing I'm the first to think of it. I'm curious to see what those PSR combined images might look like stacked in another program, which can take the best x of y exposures, for instance to enhance detail.
