It wasn't much of a night for imaging, hot muggy and drifting cloud.
I only managed one frame for an hours imaging on Lemmon. The single frame is iso 3200 2 minutes.
I thought i'd try Ison, and to my surprise it showed up on the image. Just a faint blob though. Again the same problem with the cloud, So it's a 2 minute sub iso 1600 and a iso 6400 30 sec sub stacked together.
Hopefully tonight will clear some i can get some decent time on Ison.
I've supplied a chart that shows Ison's position on that night plus relative star magnitudes.
