Nice image Peter. I'll have to check this one out. I see there's a stack of galaxies to explore in Glen C's "All Sky Messier Catalogue" I'll have to get into, including this one.
Just a thought about your "flexure" - are you sure its not just mount and guiding software manifestations. I've spent about 15hrs this week getting my head around guiding with Maxim to see what it offered. After 3 nights, I turned it loose on a series of 10min subs on Eta C only to find pretty bad smearing mainly in the RA direction. However, when I push Guidemaster (which I usually use) to 10 mins and beyond the majority of my smearing is in the DEC direction. Phd is never quite as good as GM even when I spend hours optimising it.
I know my HEQ5 is hardly a Paramount, but its interesting how different settings on different software can manifest in such different ways.
Anyhow - even though you're on an EQ6, just suggesting lofting the Newt around may require some specific tweaks in your guiding software. (Actually, I think your stars look pretty damned good in that image too anyway)
