here is a most recent image taken with the 9" tmb folded apo.
it renders one of my favourits I was very long looking forward to image.
NGC 772 is a disturbed Sb-galaxy in the constellation "aries".
the samll ellliptical galaxy in the image just below the large 772 is ngc 770.
that galaxy has drawn professional astronomical attention a couple years ago, as its core was discovered to be counterrotating!
all data on the image is on my website - as well as some more facts FYI:
