I want to report that tonight I succesfully could make an automated meridian flip with SGP and my iOptron CEM60 mount. I had this planned months ago, but between work and clouds, I had never tried it. The firmware and ASCOM driver are the latest for the mount. Also the SGP and PHD2 are latest versions to date.
Attached there are the pre-flip image (frame 2) and post-flip image (frame 3). Each one is 180 seconds at ISO 1600. The selected options were:
- Degrees past the meridian: 1
- Wait For Meridian
- Auto Center After Meridian Flip
- And also on the Telescope tab, 30 seconds for Mount Settling Time
I have astrometry.net installed on my laptop and is the default Solver. My setup is a C925 EdgeHD with hyperstar, microtouch focuser and a modified Canon T1i DSLR, and a Starshoot Autoguider on a Stellarvue F60M3 guide scope.
It is amazing to see how at the beginning of the session SGP centered precisely on the target, focused, plate solved and began to image as expected. When the second frame finalized, a message appeared, indicating that the time to the flip (around two minutes) was less than the next frame duration (three minutes). SGP paused the sequence and once the two minutes elapsed it stopped the guider, made the flip, took and image, plate solved it, placed the scope right on target again, re started the autoguider and continued with the third frame of the sequence.
You can see in the images that the pre and post flip images are very precisely framed around Marfik, which was my selected target.
Thanks to all the users and developers who worked to make this feature work as intended.
