I had a play with the latest Seestar update last night too
* ROI on the camera is still not working (but in a slightly different way at the moment, it just doesn't produce a frame rather than generating an error). I am leaving that disabled for now.
* Park and Unpark on the ASCOM driver do work, but Unpark doesn't actually bring the arm out. I had a play and ended up preferring my existing workaround that brings out the arm on unpark as you *know* it has done something. Unfortunately, the changes do interfere with some of the workaround that I had put into the very latest SharpCap update, but I have now fixed that too for consistent operation
* The driver reports that pulse guiding works and allows the guiding rates to be set - that should enable it to work with 'dither only guiding' in SharpCap, but I haven't tested it in anger
* The dew heater does indeed appear as a switch device. It would be nice to have more available on the switch device (it could readout the battery level, time left, etc).
cheers,
Robin
