I got a night and a half of Sii Friday 17th and Saturday 18th this month that wasn't flash hot but I painfully used it somehow to do a HST blend. I don't know when I'll be able to reshoot the red channel with the rain now but the colours aren't too shabby I reckon. No doubt more data will smooth the noise out and bring more details. I'll also be able to take care of those fairy floss stars. A bit green of course, but hey that's me.
