Robby, I won't get field rotation because it's not alt/az, it's EQ. Drift will depend on how accurately I've aligned it.
I spent a fair bit of time that night making sure the platform was aligned. Some of the shots to come next week was shot at 37mm for 122s, and even at full resolution there's only a tiny bit of evidence of star trails.. when it's reduced it won't be noticeable.. unfortunately though the lens lets it down around the edges with the shape of stars getting quite distorted..
I used in-camera NR as well as mirror lockup. With bulb mode set, I just used the remote to start the exposure, and then again to stop it.
RB tells me he used a light application of NeatImage.
I'll post a raw (ie: unprocessed) shot next week so you can see the (lack of) noise in the image, and how much was visible with just a single exposure, thanks to the dark skies.
You could mark that one up and post to beginners forum to enable recognition of the SCP, the Octans asterism (is that how you spell it?) is nicely visable as are all the cues for hopping to it at this time of year....
