Took a batch of M5 shots while waiting for M83 to cross the meridian.
This is using the cameras internal noise reduction, iso noise reduction and highlight tone priority.
I also managed a few flats before it got dark.
Still looks a little blue from the CLS filter here.
6 x 120sec @ iso1600.
[edit] Stuck it through a photo filter to warm it up a bit.
Nope that's through the dob and cropped. See the spikes on the star.
And it looks like the only image from last night.
The secondary dewed up not long after starting the next run
