Venturing into the north again - NGC 3184

[Stevec35]

This was mostly a test exposure taken using Dean Salman's 10" Ritchey Chretien in Colorado. The subject is NGC 3184, a nice little spiral galaxy in Ursa Major. The image is nothing special but it does show a recently discovered supernova, the blue star near the centre.

Cheers

Steve

Looks like it is a reasonably small galaxy, nicely done. Totes awesome catching that supernovae :)

[Stevec35]

Thanks Colin. Only missed discovering it by about 2 weeks. Of course not being familiar with the galaxy I almost certainly wouldn't have picked it up.

Pretty little galaxy there Steve. Nicely processed.

Thanks Geoff

Nice image Steve:)
A bright galaxy for the northern hemisphere observers at mag +9.1
A show piece you might say.
I observed the SN visually on a night of fairly good seeing with a 6mm radian
even though low down for me at 44° north was still able to pull it out.
At the time the SN was 14.5 mag.
It gives a good comparison to the SN 2016 adj in NGC 5128 with the colours.
5128 orange,3184 blue, so we can see what extinction does to supernova colours.

Thanks for the info Ron. Actually I thought the galaxy magnitude was 10.4 but I think that's the blue magnitude rather than the visual. That's a good catch picking it out visually.

Good training over 30 years of observing and about 16 years of those looking at faint galaxies for supernova's.
Missed a couple by that much:( One Robert Evens discovered only a few hours before me so no cigar the other by an american who found one in ngc1367 just a couple of hours before I spotted it.
Very cranky I was too. :mad2:
Cheers:thumbsup:

The mag should have been 9.6, and Blue mag as 10.3 or there about's.
I got to see M81 &M82 when I was up in Scotland last year, but unfortunately only through 10x60 bino's :sadeyes:
They were the only two Messier objects missing from my messier list.
I hope to see them telescopically one night before I get too old.
Cheers:thumbsup:

[Stevec35]

Both easy bright galaxies but slightly bland through the eyepiece. I haven't seen them in years but remember remarking that M82 looked like a smaller NGC55.

Nice catch, Steve! Will you get getting more northern data?

Cheers,
Rick.

[astroron]

That's why you do imaging.:P
Cheers:thumbsup:

[Stevec35]

Thanks Rick. Yes - that's certainly the plan. Currently it's a barter arrangement. Dean gets to use data from my scope in exchange for a night or two with his.

[Stevec35]

I used to be a good visual observer but my eyes aren't up to the challenging stuff anymore.

I Love your images, so you're forgiven.;)

Thanks Ron - much appreciated
