Yes that old Chesnut.  I have imaged this a few times over the years, but being stuck for anything new to do while stuck at home during lockdown, I thought I would see if I could make a better job of it with the Esprit.

However, it was almost a full Moon and then the clear skies ran out, and I hadn't got enough Oiii and Sii, so decided to see if I had any old data I could use, and went back to 2014 when I did it also from home with what was then my new William Optics ZS71 and my CCD camera at the time the Atik383L, which made it a bigger FOV and so allowed integration. 

Ha entirely from the Esprit/460

Ha 12 x 600 (2h)
Ha 8 x 900 (2h)
Ha 3 x 600 binned x 3 (error!! but decided to combine it). 30mins
Total Ha 4 1/2 hours.

Oiii with Esprit/460 8 x 300 binned 40mins
Oiii with WO/383 9 x 600
Total Oiii 2 hours

Sii Esprit/460 8 x 300 binned 40mins
Sii WO/383 5 x 600 50mins
Total Sii 1 1/2 hours

Total imaging time 8 hours

Also an HOS version
N.B. Image edited, I thought the original was oversharpened.
