You went surprisingly deep from your location though all that time had to have helped a lot.

Your negative image does show the northwestern plume much better. For some reason I've never been able to make a negative image that went any deeper than the positive. Yet most others do. I don't know what I'm doing wrong.

Transparency was mostly good, but it was quite windy at times. My (rather)
new AZ-EQ6 mount coped quite well with this. The AZ-EQ won't replace the G11
as the G11 (tuned with an Ovision worm) still tracks better, but the AZ-EQ6
is much easier to handle and much more fun, my G11 doesn't even have Goto.

My main target was Arp 288 (NGC 5221/5222) with the added bonus of NGC 5230.
All three are about 300 million light years away according to Guide9, so
they seem to belong to a physical group of galaxies. As the tidal tail of
NGC 5221 is very faint in my image I have also included an inverted version.

Taken from Berlin with a 10" Meade ACF at f/8, AZ-EQ6 mount, Trius SX694
camera, 41x7.5min Lum, 19x7.5min RGB each.
