Session Notes

M33 - Spiral Galaxy ("Pinwheel Galaxy")     Variable Stars (photometric monitoring) - None     Nearby Stars (astrometric monitoring) - None

- Very short evening session (~ 15 mins) cut short by developing clouds / overcast conditions - Main aims of the session were the testing of new routine & bug fixes and acquisition of a selection of deep sky targets, together with some variable star, nearby star and comet targets (if conditions allowed) - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding & imaging - Ambient Temperature: 9°C (min) climbing later as sky became overcast. - CCD Temperature:  -15°C - Notes from 2020-10-26 >>      -
