Dear Jean-Luc, as I mentioned in my recent exchange with Jasem, both skywatcherAltAzSimple and indi_Skywatcher_AltAzMount drivers are buggy on many front; particularly, with the AZ-GTI mount, the mount keeps slewing randomly for no reason, these are small slews but enough to slip from your target. When you try to do platesolve-alignment, alignment is continuously stopped by an error that says "slewing detected, aborting solving". Also, it's difficult to provide any stable piture of stars for plate solving because tracking is significantly bad. These two drivers, at least when connected through UDP with the AZ-GTI mount, give very bad results in my experience. Compare that with your driver, based on eqmod: I've been using it (in EQ) for months, never a bug, tracking is perfect, etc etc. So I believe strongly that the best would be to have an option in your driver for alt-az mounts. That would also alt-az users to profit from all future features added to your driver. For instance, recently a version of your driver added a feature to use the SNAP port of the AZ-GTI mount to take pictures longer than 30s with DSLRs (
) - although pictures longer than 30s are not probably a good idea for altaz operation, it would be nice to have the feature to try. Thank you so much for your work on this driver!!!
