ASTRO: M-74, spiral galaxy in Pisces

LRGB exposure (20:10:10:15 minutes color binned 2x2) with STL-1301E camera
thru a 20" F/8.1 OGS RC Cass.

Here's a link (http://www.kopernik.org/images/archive/m74.htm) to a page
with the same image plus images of M-74 and supernovae SN 2002ap and SN
2003gd. These images were taken with my ST-9E camera and both were
apparently on a night of better seeing (or I did something else better back
then).

Like those HII regions.
Much better color than I got in my attempt. My color processing stinks.
Better seeing too. Like those HII regions.

Thats a cool shot George. Clear Skyz, LA

George,

one of my favourite galaxies. Nice image.

Thanks Rick!

I'm generally not to good at getting color balance. Also, my old shots with
this galaxy using my ST-9 have more resolution. I don't remember if I was
using an AO-7 at the time, but I suspect it's just a seeing effect.

Stefan,

I'll probably give it another try the next time it hosts a supernova!

Ah, yes the Phantom Galaxy. I have seen this barely with the naked eye. Barely making out a galaxy
with arms. Now I see what I was missing...
Nice...

One of these days I've got to observe this galaxy with a really big scope -
like a 30 inch Dob or similar.

PS: I only thing of getting a 30-inch for a minute or two before realizing
that I'm nuts!
