Flat Galaxy Catalog is another catalog I've been mining for targets.
This is one on that list. I've been so tied up with Arp's I've not
thought about it until the one in the APOD reminded me. Interestingly
that one ISN'T in the FGC, not quite flat enough! The APOD image has
lots of IR in it. Looking at the POSS plates of that one the blue shows
a rather nice bulge not seen in the APOD/HST version. Red lesser and
virtually none like Hubble in near IR. FGC requires an 8:1 or greater
ratio in blue light, revised catalog says it has to meet that in red and
blue light. Or so I've been told. I've not started on it in earnest so
haven't done my own research as yet.

This one appears slightly tilted to me yet still is just a thread in the
sky. Yours came out quite well. Lots of motling along the thread.

I am hit by weather too which is common this time of the year. But when
clear normally here seeing is fairly good. Not this year. Even when
clear it rates a 2 at best. At that level I can't really even find a
focus. Normally a move of 25 microns is enough to see a focus change.
With the seeing of late I can move 250 microns and not see a change!
That's bad! I hate it when it is clear and yet a star shows a 5" FWHM
instead of around 2".

I've a lot of images acquired with very poor seeing. I consider them
survey images and those that interest me go on a re-shoot list in
hopes that I'll have some good seeing the next time they are available
for imagiing.
