M&T sublimely deep image of this object is a pretty hard act to follow...particularly in a theatre where there are 4 million natives besotted with bright outdoor lights....anyway....
The image link is here
A back of the envelope calculation says I'll need at least another 10 hours or so of exposure with my "small RC16"
to match the flux gathered from the venerable 20" ......then there is that skyglow problem....
Grizzles aside....I have to say I am very pleased with the 92mm field corrector...due a small registration difference, the image is just a few pixels off a full frame, yet the stars are beautifully corrected to the edge of the chip.
I departed from my usual processing and delved into PixInsight a tad more. I'm now a total convert for PI's registration and integration tools, which was used for the above dataset....
