I am going to try increasing the Proximity slider in EQMOD to see if it helps. By default it is set to 0 degrees which I am guessing disables it but I can’t find anything in the documentation. Below is the description of the setting from the EQMOD docs.
Use the EQASCOM “proximity range” slider to prevent clusters of closely packed alignment points.
When adding a new alignment point a search is made of the existing points and any that fall within
"range" of the new point are automatically removed from the list. The allowable range is 0-15 degrees
in 1 degree steps. So if set to a maximum then any point within a 15 degree movement of either the
RA or DEC axis would be removed.
I also found this on the Alignmaster page that seems like a similar issue. I will try to switch EQMOD from Append to Sync to Dialog Based.
Just a word of caution about using EQASCOM in combination with Alignmaster. You must make sure that the EQASCOM pointing model is disabled whilst alignmaster does it’s stuff. So star by clearing out any existing model and put EQASCOM into “dialog mode” for alignment. This is because Alignmaster works by issuing a sync and you want this treated as standard ASCOM sync rather than as a trigger to add an alignment points. Once finished with Alignmaster you are free to reload an existing pointing model and switch to “append on sync” mode (if you prefer it).
