Cheers TJ! Yes, stupid mistake to not have a guide star selected by the MOAG. Should have double checked.
The framing of this target took some planning. Its quite a large target so framing was critical given the small field of view. I thought I had it all organised in TheSky so that a guide star was selected...alas come to execute the plan, it all fell apart...so I made the most of the data anyway.
The slight elongation was "partly" resolved using a kernel filter. For those interested, more information can be found here -
