Despite pessimistic weather models, this past Thursday turned out to be the first clear night I’ve had for observing since last September. While I was late getting started (due to said pessimistic models) and also my first time trying to setup in the yard of our new house, it turned out to be a pretty ideal night. Rather chilly (better for my uncooled 800D if not so great for me), and clear of clouds until past 4AM.
After getting setup and aligned, I was able to catch about 30 minutes of the Pleiades before they dropped behind a nearby tree (may make it into another post if I can get a reasonable image out of it), after which I turned toward M51 again as it was set to make an arc from the east across the zenith. Ended with 95 out of 111 two-minute exposures usable for integration, over twice as much data as my last attempt at M51 in August.
Flats still were a pain, as I still don’t have a flats box and didn’t get setup early enough to take twilight flats, so I had to stay up till I had enough dawn light, but had issues with morning clouds resulting in uneven exposures, turned out alright though and I couldn’t make out any defects caused by them.
All calibration, integration and processing done in PixInsight. I’ll write up another post going over the processing for this session.
