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.

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. Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.

Doug, thanks for imaging this one, great shot. NGC 3938 is probably my
favourite galaxy. Stefan "Doug W." schrieb im Newsbeitrag . .. The second image of the night had FWHM at 3.0" Full size and info: http://www.wheeland.us/galaxy/ngc3938.htm -- Regards, Doug W. www.photonsfate.com -- |

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. -- Regards, Doug W. www.photonsfate.com -- "Rick Johnson" wrote in message ...

Thanks everyone... no good guide star for this guy on the east side so the
galaxy is not framed well. -- Regards, Doug W. www.photonsfate.com -- "Doug W." wrote in message . .. The second image of the night had FWHM at 3.0" Full size and info: http://www.wheeland.us/galaxy/ngc3938.htm -- Regards, Doug W. www.photonsfate.com -- |
