Is this 3 x 35mm fields on the QHY9?
Thanks Rob. Yes it is 3 panels. The Barnard Loop and the Eridanus Bubble were framed separately. The panel in the middle just bridges the gap and it's only 2 subs. With the QHY9 the FOV is 29x22 degrees at 35mm with an image scale of 33asp. No problems imaging in high winds but focus is a challenge. So from Taurus to Orion you have probably close to 90(ish) degrees. I intend to add monoceros down the line.

Not much choice about the framing actually because of horizon restrictions. Here's a snapshot of my 'window of opportunity'. That's why I want to reshoot from dark skies.

The easiest way to find the Eridanus Bubble is to center your field on the pleiades (M45) then go right up by 15 degrees. You'll be smack bang on.

Thanks Rick. It 's just going to take a little planning an time but not overly difficult. Just very wide. There is very little distortion from Taurus to Monoceros as it's fairly high. The challenge is that's it's pretty darn faint and requires a lot of subs.
