For a variety of reasons, I only got 4.5 hours of luminance on this, but the central zone is fairly bright, so it worked out a bit better than hoped with only minimal noise reduction.
there is a wide variety of colour approaches on the web, with many showing much more red - however, this scheme is about what PI suggested from the two approaches to white balance.
that looks simply sensational. must view on full res.
really envious of your round stars too! I like the colour too.
there are a few red pixels in the back ground with a higher concentration in the lower left if you can be bothered dealing with them.
all the best,
rusty
Thanks very much Rusty. the EQ8 seems to do OK on stars, which is just as well...
Thanks for pointing out the red spots - I did not see them. I used 2x2 darks that had been synthesised from 1x1 versions, but they clearly did not quite do the job on the red data - hopefully have now cleaned up the worst. Will have to get together a native set of 2x2 cal data, now that I have settled on binning 2x2 for colour data.
The main galaxy is reminiscent of what I would imagine the Milky Way and Saggitatious Dwarf Galaxy would have looked like a few hundred million or billion years ago.
The smaller galaxy looks like it is moving to the left and dragging some of the spiral arms with it
For some reason, I have never been a fan of this galaxy and always glossed over it but that certainly doesn't take anything away from the high quality of this image Ray, something we have all come to expect and enjoy from you ....so thanks for not having my irrational phobia

thanks Colin. it is certainly interesting to think that this might be similar to our home galaxy.
actually, I also think that it looks a bit like a Constitution class starship

Thanks Mike. Although it isn't the prettiest one out there, I was pleased to see a little of the structure of the galaxy and evidence of the interaction with 1531.

Oh yeah I agree...I think you may have even turned me....

that's very generous Steve - thank you.

Thanks Aidan. I think it will be a good target for a longer exposure follow- up next year. I was surprised how much structure is visible at such an edge-on view angle, but the view angle also ups the surface brightness, so that helps.
Lovely. Lots of detail. A powerful demo of things that go bump in the night.
Must have been hard to get the colour balance right, because of the glare from the brilliant blue topaz star. Your rendition seems a pretty fair choice.
Very nicely done Ray! An underrated galaxy for sure but it needs FL to do it justice.
Cheers, Marcus
thanks Marcus. Agreed, a little bit less than 0.91 arcsec/pixel would have been nice.

Best,

thanks Mike. I used the two PI colour balance methods (star based and galaxy based) and got basically this result from both. The colours seemed plausible, but who knows.
Meeeah...I dunnooo Marcus baby I keep hearing this, but in the end image scale is image scale, isn't it? One of the best long FL amateur images going around is Martins (your TOA shot is good too) and I don't recon it is any better than Ray's which is at a much shorter FL The real clincher is the seeing, if that is good then a better image scale can do its thing.
That is a real beauty Ray. I would be very happy with that if it was mine. I really like the pastel colouring and the detail in the galaxy. The tidal distortions really makes this object in my opinion.
Its on my list of imaging targets once I get my camera sorted again.
Simply....Wow! I have always found this glaxay set to be very appealing, and often referred back to Martin Pughs version as the benchmark. However now, I'm most impressed with this version Ray, and it now is my preferred reference. Excellent detail that keeps me focused upon the primary galaxy. For capture through to processing this is an excellent result. "Well done!" is simply not enough!
....so thanks for not having my irrational phobia
