NGC 4945 - Colour Added!

Here is the colour version of the Luminance image I posted last week. Saturday was a great night - zero clouds all night long and seeing quite good after midnight. In fact, I can't remember a night in the last 8 months where clouds haven't dogged me at some point! Anyway, I managed to get 80 mins each for RGB (binned 2x2) on top of the 2 hrs Luminance for a total of 6 hours of data. I went 2x2 because I was at F11.7.

My processing was inspired by Rob Gendler's version. I like seeing vivid colours in a galaxy image. The halo turned out a treat too I think - so quite pleased overall.

Small: http://www.pbase.com/gailmarc/image/110479642/large
Large: http://www.pbase.com/gailmarc/image/110479642/original

I may yet go for some more data, but this will do for now!

Cheers, Marcus

Nice! The dust lanes in this galaxy look pretty full on. Heaps of colors

Stunning Marcus, the dust lanes standing out so well against those delicate colours.

This is an excellent image Marcus.

Sure, with better seeing, bigger 'scope, ( preferably in low earth-orbit) you could do better.

Gotta be happy with that.

Excellent job Marcus

It's an awesome galaxy

It does look a bit close up to me, like I wish I could zoom it out a bit to take it in properly and hide the processing a bit..?

Wha tha? Too closeup????? I can see Freds startled face now

Thanks Marc, Steve, Paul, Allan, Rob & Craig. Glad you liked it! This galaxy wasn't on my radar until recently and I went for it because of it's vibrant colour & riot of dust lanes. The extent of the halo was an unexpected bonus.

Thanks a lot Peter. Yep, a few moonless nights of sub arcsec seeing would be nice! I live in hope. Bigger scope? - maybe one day. I do occassionally daydream of owning a 14.5" RCOS'. I am amazed what a mere 5.9" scope will do though.

Cheers Mike - appreciate that! Waaa?? ......... too CLOSE UP!!!! Ya just can't please some folks can ya!! Seriously though, I'm not a big fan of the small-galaxy-in-a-large-featureless-star-field look unless it's a cluster.

Hide the PROCESSING!!!!! Here, look below, I've attached the completely unprocessed RGB frame (initial stretch only, 50% scale & massively compressed) for your enjoyment

Thanks guys. It does kind of look like it's on fire, I think it's the inferno-like look of Rob Gendler's rendition (see here) that I liked.

Cheers, Marcus

Ah, I thought you had heavily cropped the image.

Ok it needs some work - gradients, coax out the outer halo a tad etc but the full frame version is quite natural looking. I think you could crop it a bit but just not as much as the version you presented IMO. Might be nice to see a couple'a different versions even?

Still, either way, nice work

Mike

Thanks again Mike - but I only processed the crop on this one. The full frame is on the cutting room floor where it belongs. Besides, Rembrandt only ever painted one version of his pictures, right?

Cheers, Marcus

Oooh mate! That is drop dead gorgeous.

I agree with Fred one of the best images for ages. Super well done!

Roland Christen remarked several months ago about the virtues of
barlowing up an APO to get maximum resolution. You are really showing that to be an excellent way to go.

You would be very hard pressed to better that result even with a large RC.

You are showing an excellent APO has real real depth potential. Not everyone likes the diffraction spikes of compound scopes.

That's it, I'm ordering the Baader FFC from AP!

Greg.

Excellent Marcus. I have to agree, I also like the rich colours you've brought out. Visually pleasing in many aspects. DM award contender indeed.
