ngc300

Hi

after months with wall to wall cloud (and the associated depressed spirits), finally a break and some fairly good seeing. Minimal processing and some noise in there, but that was the only way to keep full star resolution. Also, there is a very interesting galaxy group below the main galaxy - some look to be quite significantly red-shifted.

Thanks for looking - really appreciate any feedback.

Regards Ray

Really nice, Ray! What were the exposure details? They aren't listed on Astrobin. I've not imaged NGC300 before but it looks like a pretty dim target...

Cheers,
Rick.

That's just plain, old fashioned excellent Ray!! Great resolution, natural feel to the colours ... just a beautiful field. Can't fault it. A bit of Ha might be nice though. How much exposure?

Thanks Rick. I don't know the surface brightness, but under moderately dark skies it took about 100x5min lum and about 30x5 for each colour, all 1x1.

Thanks very much Marcus - guess I should get some Ha to emphasise the star formation regions, thanks for the suggestion. exposure details in previous post. Thanks for the feedback on the colour: there is not much on the internet to use as a template for this galaxy, so I relied on the PI colour calibration.

Nice image Ray.

I like this galaxy - but it isn't easy, surface brightness is only 23.01! (according to DSO-Browser.com). It's a bit like NGC6744 - looks like it should be easy but it isn't because of it's low surface brightness. Needs longer exposures than I can do.

Be a few mega $ telescope owners (or soon to be owners ) out there going DOH! Ray

Bloody Beautiful mate...bloody beautiful

Get the right image scale and seeing plus some good processing and voila!...you win!

Nice work Ray, good colour and good background and interesting detail.

BTW that is an interesting group below the main galaxy.

Well done Ray. Really good details in the galaxy and nice colour. I read somewhere that this one and ngc55 used to be considered part of the sculptor group, but it seems from new red shift data that they are not. However, ngc55 and ngc300 are gravitationally bound.

Top image Ray,
Plenty of background galaxys.
You give me hope for what I could do with my 10" f4 Newt
& you're using an RCC1 like mine too:

That's an awesome image Ray. Fantastic natural processing as well. Stars are terrific.

These galaxies are massive distances away yet your image clearly is distinguishing many of the larger bright stars in it. Phenomenal when you think about it.

You really nailed it.

Greg.

I'm not sure I've seen a better job on this one.
Beautifully processed. Most of all just really loved exploring the hi-res

Just stunning, Ray. Something to spend a lot of time coming back to.

As I look at it, I get the distinct feeling that there are two sets of spiral arms, transparent, overlapping, but quite differently wound.

Love the detailed background critters too. Beautiful.

Just about to go away for a long weekend Ray but I thought I'd just leave you one of these before I go....
