Indeed. I tested the waters on this object with my 305mm F3.8 Honders...and was not at all happy with the result.
(sharp but not enough scale)
There are not many people doing narrow field, high resolution imaging on IIS ( there is a big difference in images that look sharp and ones that have truly high resolution)
and to be fair it's not easy....as even the slightest equipment issue becomes obvious when the FWHM's head toward 1.5 arc sec.
While the data in this image is OK, it's not at the top end of what my imaging system has been able to produce...with seeing being a VERY big factor.
What I do like about the system is the pristine stars across the entire 16803 chip...no simple trick IMHO.
