Gambled on the weather last night in Sydney and thanks to the new ACCESS data that was made available recently it seems to have paid off nicely. The night was relatively dry, with a little wind after sunset but it calmed down straight after and the seeing wasn't bad at all. Guiding at 2.8m FL is always interesting but I'm fairly happy with the data collected so far. Still a little on the furry side but personal best to date at that FOV size anyway. Alnitak didn't bother me at all. I was surprised because the same FOV with the Mewlon proved very problematic. I've attached the MEWLON 210 shot for comparison.
So this is 135min in 5min subs on a G11, C11 at prime and QHY9 mono, Baader Ha 7nm and OAG/lodestar. Not much light getting in at that FL especially Ha. Flats took 15s with the EL panel to full to register 10000ADU. Probably would need twice or three times that amount of data but the details and contrast are starting to come through.

I added some spikes. I like spikes.
