Nice framing too, whats your FOV?

Yes I did squeeze a lot out of it didn't I?
The D800E is about the same sensitivity as my Proline 16803 albeit noisier as its not cooled. It would be tempting to have a modified version to pump it up even more but its too expensive for that.
Not sure how wide the FOV is. About 6 degrees?
I was happy to be able to get round stars at 180mm focal lenght with the little Polarie. Luckily the Nikkor 180mm is a fairly light lens. I really like this little Polarie.
I also have about 30 of these same images to stack so that will be another version. I also have a time lapse of it and a series with an 85mm F1.8 lens at F2. The comet was noticeably brighter last night - about 15% brighter and the tail is becoming more visible. Another few weeks and it could be quite bright.
