Pretty. Looks like that one has a tight ring around the nucleus then
the arms start from nowhere out beyond it. Otherwise it looks like a
pretty normal face on spiral.

Correct domain name is arvig and it is net not com. Prefix is correct.
Third character is a zero rather than a capital "Oh".

Another interesting one. I like that inner dust band. At first I
though it on the far side but in the full size image it obviously goes
in front of the nucleus. Neat.

How do you keep satellites out of your long sub exposures? Seems half
my attempts at 30 minutes have a satellite trail. I must attract those
guys.

Doug, thanks for imaging this one, great shot. NGC 3938 is probably my
favourite galaxy.

Thanks Rick... I like the 30 min. subs because I don't need so many
sub-exposures to process and there are a lot less readouts for the total
image time.

I think that dust lane is in towards the core too.

Satellite and aircraft have not been a problem... my small FOV reduces the
chance of seeing them... but I process the trails out if I get them.

Thanks everyone... no good guide star for this guy on the east side so the
galaxy is not framed well.
