The final Ha stack will have a narrower field of view, probably quite similar to yours as I started this target with a SW130pds, 585mm focal lenght and a QHY183M but I collected some more Ha and some Sii with my AT106, 690mm focal lenght and the same camera.

I look forward to seeing the finished Ha image.

I finally managed to stack all the Ha

78x300sec with my qhy183m and 130pds and 16x600sec with the qhy183m and AT106.

Fantastic image Steve - and a superb write-up on the object and the How!

A lesson for me in there, certainly!!

Another target added to the To-Do list

Perfect scale.  Propeller is crystal clear
