Hi everyone

Nice to have a fast reflector for the weekend, enabling this sort of shot in just 2-1/2 hours, UHC filter notwithstanding.

Don't believe the horror stories you read about -in our case- f3.9. You collimate them in just the same way as you would any other Newtonian and with simple modifications, even the most budget of cheap models hold collimation all night, every night. Another one we're not certain about is the temperature. In a minimum ambient of 24º, the sensor was around 32º; the background is a mess -or maybe that's what it's like-  but nothing a few hundred frames more won't fix! Anyway, 32° doesn't spell impossible, so don't put away your gear.

We'd also planned on the Pacman nebula, but the Mediterranean haze blew in on the easterlies, so it was cool beer only from around 01:30.

Thanks for looking and dslr users, do post your experience of the same.
