Deep field NGC7000/IC5070/IC5067

Well, although forecasted as a clear night on Wednesday, the clouds did roll in every now and then… but in between them, the seeing was great, very still indeed. A bit blustery, so I swapped my OTA and target from Iris Nebula with the MakNewt to using the Borg 77ED@f/4.3 and the North America nebula and Pelican Nebula. I knew the cloud would cause some issues, and transparency wasnt as good as I would have liked, so I decided to image in Hydrogen Alpha. Looks like it was the right choice 🙂

Highlight of the evening – sitting in my moon chair on the lawn, leaning back and looking south, a incredibly bright meteor lit of the sky, with the trail it left behind glowing for 5-6 seconds. Not often you get lucky enough to be looking in the right place at the right time:)

“Whoah!” moment of the evening – PHD deciding that the strobe light from a passing aircraft was a better star to be guiding on than the real guide star. Yes, it did pass RIGHT through the FoV for the guide scope.

Mount: EQ6 via EQMOD
OTA: Borg 77EDII @ f/4.3
Guiding: SW ED80 + SX Lodestar + PHD
Imaging: M25C + MaximDL, 21x900s, Astronomik 13nm Ha (101 bias, 101 flats)
