hi folks,
this time I 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.
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.
This would be Martin's website:
http://members.liwest.at/picard/
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 also 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:

hey - who has ever imaged that guy?...
thanks for your comments!
