ASCOM Driver crash when using TouchNStars Plugin and NINA #67
Description
The Ascom Driver crashes when I use the Touch'N Stars Plugin in NINA for manually slewing the mount into a position. Both RA and DEC movement requests let the ASCOM Driver crash, and also the mount becomes unresponsive and needs a power cycle.
ASCOM and NINA logs attached.
Many thanks for having a look, very very much appreciated!!!
