hi folks,
This time it is a privilege to present a very unusual and hardly known galaxy,...at least this is what I think, after searching for images on the web, taken by amateur-collegues...couldn't find many ...
well, this galaxy is quite huge (12.9 by 5.9 arc minutes) but brightness is extremly low!
the final result you will see is a collaboration between my observatory neighbourgh and close friend over more than 20 years Martin Winder and me.
Martin used his 16" RC f/6.5 (2" starlight instruments reducer) and ST 10 for image acquisition:
lum in 1x1 color in 2x2 bin.
He could take advantage of a couple nights with very cooperative environmental conditions in both, seeing and transparency.
he preprocessed the entire dataset (dark calibration, alignment, normalize and stacking); then I came into the play, having some fun and also a bit of a hard time processing L,R,G and B. it was a challenge, as the object's data was vaguely some 140 counts above the background...
end of speach - here is the result, guys:

BTW:
hey - who has ever imaged that guy?...
contact data:
This would be Martin's website:

best wishes,
