lx200 protocol expects RA/DEC in epoch:now #116

Closed brickbots closed 8 months ago

Fix our implementation of the lx200 protocol. The protocol expects coordinates in the current epoch and the PiFinder is using J2000 (as per the hipparcos catalog that underlies the plate solving). This was leading to a mis-placement of the telescope reticle in apps that were connected to the PiFinder.

This patch processes the PiFinder solution to the current epoch before sending out the coordinates via the lx200 server.
