Hi

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.

Stunning image Ray, as per usual :)

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 :)

[strongmanmike]

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 :thumbsup: ....so thanks for not having my irrational phobia :P

Mike

[Shiraz]

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 :lol:

[Shiraz]

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.

[strongmanmike]

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

Mike

[multiweb]

That's just awesome Ray. Inspiring. :thumbsup:

[Stevec35]

Top image Ray! One of the best I've ever seen of this galaxy. Wish I'd taken it.

Cheers

Steve

[Somnium]

absolutely beautiful as always Ray. i love this target, a really interesting galaxy.

[Shiraz]

cool :thumbsup:


thanks very much Marc


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.

regards Ray

[marc4darkskies]

Very nicely done Ray! :thumbsup: An underrated galaxy for sure but it needs FL to do it justice.

Cheers, Marcus

[Placidus]

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.

Best,
Mike

[Shiraz]

thanks Marcus. Agreed, a little bit less than 0.91 arcsec/pixel would have been nice.


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.

[topheart]

Well done!!
Cheers,
Tim

[Camelopardalis]

Wow Ray, that's stunning :thumbsup:

[strongmanmike]

Meeeah...I dunnooo Marcus baby :confuse3: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 (http://apod.nasa.gov/apod/image/1007/NGC1532_pugh.jpg) (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:shrug: The real clincher is the seeing, if that is good then a better image scale can do its thing.

Or am I missing something profound here :question:

Mike

[Paul Haese]

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. :(

Well done Ray. :thumbsup:

[stevous67]

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!

Love your work!
I really do like the colours you bring mate!
Gorgeous.

[gregbradley]

Same, love your work Ray, always a pleasant surprise to see your fabulous images.

Very nice.

Greg.

[Shiraz]

thanks very much Tim!


Thanks very much Dunk - appreciate your comment


Thanks again Mike. As far as I know, it's all down to seeing and scale. Seeing here is occasionally better than the 2 arcsec design assumption, so I was thinking of going up to about a 1.2m fl scope with the H694 - which will give about 0.75arcsec/pixel (ie identical performance to a 2.4mfl scope on a CCD with 9micron pixels).


thanks very much Paul. Yep, I like the tidal structures as well. Sorry to hear that you are having camera problems - a real pain.


Thanks very much for your generous comments Steve. Very pleased that the image is of some value to you.


Hi Graham - thanks very much!


thanks very much for the encouragement Greg - appreciated

regards Ray

[PRejto]

Hi Ray,

Wonderful image and super colour!

You beat me to it! I've got about 12 hrs luminance and 12 hours RGB to process. Unfortunately I messed up the calibration frames and now find myself on an extended trip unable to work. Oh well, one day. You've set the bar really high. Bravo.

Peter

[Fabiomax]

This is absolutely fantastic. View full resolution is really exciting. What's your setup?
Cheers,
Fabiomax

[codemonkey]

Beautiful work, Ray.

[AG Hybrid]

Truly outstanding!

[Shiraz]

thanks very much Peter. was wondering - the sub you posted elsewhere looked good - looking forward to your version.


thanks very much Fabio. I use a 250mm f4 Skywatcher Newtonian with an RCC1 CC, EQ8 mount and a Starlight Express H694 camera.


thanks Lee - appreciated


thanks very much Adrian!

[Regulus]

Superb. Lovely to look at at the Full Screen Res. Very nice.

Very classy, Ray! Subtle colours and great detail. You've even made a convert of the Strongman :lol:
