Very nice Marc, that 183 does a great job pulling in data, is a gain of 400 a lot, or is that around unity? (Cant keep up with all these cameras and no set standards for gain/offsets)

Thank you, shame about the halos on bright stars.
Think it is reflection from filter?

398 is unity gain, I just round it upto 400
yes it really is a good camera & the dreaded star burst is easily managed with calibration frames

Beautiful, Marc.
Love me some Jellyfish. It has some amazing definition to pull out of it.

Thanks mate.
To be honest I was worried about the moon but the triband filter pulled through

Excellent shot. Looks like that triband filter works really well when there a lot of moon light. Where you able to set some of the subs before the moon came up to compare the images before and after moonrise.

Thank you.
To be honest I haven't really compared the exposure in the subs from when the rose & became a potential problem.
All I can say is that the histo in APT preview didn't show any dramatic changes during the course of the night.
Its also worth mentioning that Gemini was almost 180 degrees (opposite) the moon so in theory so what safe from stray light.
