I have the SyncToAzimuth methd implememted in my dome driver. Sometimes, my dome is not quite aligned with the scope and to fix this I can use the Sync command from SGP. However, SGP asks for an azimuth to sync to. Because of the dome geometry math, the dome azimuth is not the same as the scope Az, so my question is how do I know what number to enter into the SGP Sync dialog?
At present, I ‘cheat’ because the MCU code I wrote to implement slew to azimuth prints the requested dome azimuth to an LCD screen. So I can see the requested dome az and type it into the SGP Sync dialog.
However, I am in process of moving my observatory to a remote location and won’t be physically in it when a sync might be neccessary.
In an ideal world the scope and dome aperture should be perfectly aligned, but despite carefully measuring all the offsets and entering them into sgp, I do get occasional misalignments.
I have watched the system go from a location of ‘perfect’ dome and scope alignment to a misaligned state when a sequence moves from one target to another. The dome does goto the requested azimuth, but is not poperly aligned.
Currently my Observatory is in the garden about 10 feet away from the house and I run it remotely by using a remote desktop connection.
Any thoughts or help on this greatly appreciated.
