2I/borisov
Attempt to catch boris, on dec 6, at Lowe observatory at Bendemeer, about 2 days after the fires approached the dome 3 times and was water bombed lights at 10 secs, ISO 25000, stacked with AutoStakkert, altitude 1100 m, some smoke 3 comets spotted that night by Chris Wyatt, the local comet watcher, all around Mag. 15. The reason for short exposures and very high ISO, was because periodic error in RA and no guiding. Also the collimation is poor because had to rotate the tube for each comet to be able to access the eyepiece, It's a big scope. we would have had to collimate before each comet and we had no time, sunrise was approaching, as It was It ruined 40 light frames.
We are having trouble stacking and any help would be appreciated. We would prefer stars trailing and the comet stationary.
