ASTRO: NGC 1156

I must have come home late on September 27 last year as I only started the
imaging session at half past three in the morning. I did not take RGB
images, which is a shame as the central part of this galaxy is bright enough
to give decent colour even under my city skies.
Btw, this was the first picture where my G11 mount was equipped with a new
high precision worm by Ovision, which reduced the PE of my mount from about
+/- 4 arcseconds to about +/- 2.6 arcseconds. It didn't alter the fact that
the PE occurs rather fast sometimes, but at least the fast "ramps" in the PE
curve are smaller now.

Taken from the middle of Berlin with a 10" Meade ARC at f/6.7 on a G11
mount, SXV-H9 camera, 26x5 minutes.

The picture can also be found at

I was wondering if you'd gotten that installed. That is an odd little
galaxy.
