Seeing Last Night in Sydney

Went out last night at around 9pm and the seeing in Sydney was tremendous.
The Sky under Bortle 8 was blackish not dark smokey grey and could see plenty of bright stars which were pin point and no scintillation.
Unfortunately cloud rolled in around 9.30pm and didn’t clear until the early hours
I ran PHD2 for 20mins just to test atmospheric stability and guiding was around 0.40 to 0.50 in the East up at only 35deg Alt on the EQ6-R ( payload 15kg ) , really tight and stable with short and few Ra corrections, Dec was rock solid and with minimal corrections
Tonight and tomorrow night are looking clear all night until morning
Hopefully similar seeing conditions
Did anyone else have a peek outside last night early on ??

I was keeping an eye out last night too, but unfortunately didn't get any cloud free skies from sun-down until I gave up around 10.30pm. Cloud Free Night was predicting clear skies but it just didn't happen for me. When I read your post I couldn't believe that you had clear skies until I read on and realised that they unfortunately didn't last Fingers crossed for tonight Martin! I have last night's plan ready to roll.

Lithgow seems to be under one giant permanent cloud. Though the sun was out this morning, long enough for the grass to grow another 3 inches and get some washing dry (hopefully).
Cloud has rolled in now and we're supposed to be getting a week of sold rain or so I've been told. I was expecting it this morning when I woke up to be honest.

Martin yes I also set up around 9 with the hope of a clear night as predicted. I was aiming at m1 (low and into the city cbd lights) but still excellent guiding…for 20min until the cloud rolled in. Left everything out hoping it would clear but just wasn’t to be. Next 2 nights look promising

My last couple of sessions in Melbourne in Bortle 6 skies have been excellent with guiding of 0.3-0.5 on my EQ6 with the belt mod and my big APO I don't know what it is about the skies when they are clear at the moment but more of it please!

I was out in my backyard (Bowral) from 2030 to 2200. Transparency was OK but seeing was dreadful. I could only just make out the companion to Adhara, and the airy discs were blobs.

Ended up being quite good here. It was awful right after sunset till about 10 with quite a bit of cloud and insane heat from our concrete jungle but settled down and extremely stable all night after that

Conditions last night were similar to the previous night
High cloud cleared around 9.30pm and seeing improved to the early hours
Finished imaging around 3am
2 consecutive clear, reasonably stable nights with no moon around is a rarity in Sydney but very welcome after months and months of cloudy nights

I conked out around 1.30am this morning. I had to be up again at 6am so it was all I could take lol. Conditions were great compared what we usually get. It was hard to believe that we could actually get 2 nights in a row!!! I hope that you managed to get some good data Martin.
