After a lot of frustration with it, I have decided to give up totally on Elbrus. Its “hit rate” is just too low for me and I am tired of waiting for the all-but-inevitable “invoking failover.”
The local server version of astrometry.net seems to deliver solves sufficiently reliable that Elbrus will not be personally missed.
Last night was the first session since I set astrometry.net as my only solving software.
All went well except I got flaky results from the “Center Here” function. It did not “center” on the point I had selected. It completed the plate solves and slewed the mount but centered on a point about a third of an image width “off” in the E-W direction. It did this consistently.
Any hint as to what could produce this strange behaviour?
