Hi, I'm a big fan of BYE!
With BYE, PHD2, DSS and a few other applications, I'm able to do pretty much everything I want in astrophotography but I'm still encountering one big hurdle with my setup. That hurdle is differential flexure. I use the PHD2 comet tracking tool to make corrections to compensate for flexure drift but it's not a great solution.
It would be great to have a system that could automatically correct for differential flex and I think BYE could be made to communicate with PHD to do just that! Here is the basic idea I have in mind:
- Add a routine to BYE so that after it downloads a photo, it calculates the amount of drift in star positions between the last 2 (or more)photos...something like the dx and dy parameters output by Deep Sky Stacker.
- Now we know the number of pixels shifted and the time of the exposure, and that information can be used to calculate the rate of pixel shift in the X and Y directions
- Using this drift rate, BYE can now make regular commands to PHD2 to move the lock position at the same rate (but opposite direction) as the drift due to differential flexure.
- With this construct, the effects of diff flex could be almost entirely eliminated automatically and that would be awesome.
I hope I am being clear with what I'm proposing because if this feature were added, I think it would be hugely popular with folks that have modest astrophotography setups like mine.
Thanks very much,
Ken Sharp
