I held back quite a bit on the repro. Kept things simple. Better result IMO.
This was taken over 2 new moon periods (May and June 2015). I had about 8 hours data, but the seeing was a bit up and down so I tossed out an hour and a half or so.
It's a nice object, but very small--about twice the angular size of Jupiter.
Telescope: 12.5" Plane Wave CDK
Camera: FLI Proline 16803 (Real waste of real estate to get to this heavily cropped pic)
Mount AP900
Exposures: 10 x 10min each of L, R, G and B
FOV: 15' x 11'
Processing: PixInsight
That came out ok Geoff there is some nice detail in 5189 itself and I like the colours. Am I right in thinking that the seeing may have bloated your stars a tad more than you would have liked and you have worked to reduce them, as they don't look like your normal stars.
I think we're forgetting that this is a very tight crop on a tiny object done without the benefit of narrowband filters. There aren't too many straight RGB versions of it out there.
A serious challenge in natural colour. The star field shows how sharp and tight the shot is.
Thanks Mike. However, in view of various comments below, I think a more careful reprocess is in order. Watch this space.

Really impressive colour processing
Thanks Peter. Some nice tight luminance on a good night would certainly help.

A pleasing view none the less, nice work
Mike
Thanks Mike--the eagle-eyed Sidonio hits the jackpot again. I'll have another go at it.

Greg.
Thanks Greg. Perhaps a shorter exposure to stop the star saturation and also knock down their interference a bit.

I decided to repro this for obvious reasons if you compare the before and after.

Great job on the repro Geoff looks very nice, the colour is spot on I recon ...yes, excellent use of the 16803 chip real-estate ...just for a laugh, I'd love to see the full frame actually, I contemplated doing several objects like this when I had my 16803 on the AG12 but always balked, now that would have been completely ridiculous
Got the thumbs up from me Geoff. Good colour. I am thinking the only thing that could make it better is adding a bit of NB detail. I like the new version.

Thanks Mike. have a look at the thumbnail for a full frame view. It's not actually all that small.

Thanks Paul. I may be able to give NB a try when I next get down to Wiruna.
