Fantastic image of this galaxy Rick, the equipment and supplied data is top quality for sure but your processing is spot on, very nice job :thumbsup:

Best I can recall of 6744.

Dumb question - wondering about the reason less subs in R than the others. Is it because the Ha picks up the shortfall to some extent? Or was the S/N good enough to stop at 6?

That image is Devine. Heavenly even. I don't recall seeing better either.

Thanks, Louie!



Thanks, Mike. For a change I don't think I went too far with the contrast and saturation. Maybe I got away with the decon too :lol:



Ta, Troy. It was a typo... actually 9x1200s Red. I would have liked more but that's all we managed to get so far between weather and moon. You make do with what you have :)

Rick (and Martin) that's an astonishing image. Superbly done.

Wow! Loved panning around the image and taking it in all that lovely detail and colour, and finding all those other tiny galaxies in the background.

Nothing much to say Rick except that that's a superbly detailed NGC 6744. Well done!

Thanks, Kevin.



Not my kind of music, Lewis, but thanks, I think :lol:



Thanks, David.



Thanks, Peter.



Ta, M&T.



Thanks, Ben.



It is indeed, thanks Marc.



Thanks, Greg.



Thanks, Pete. Back just in time for Astrofest :)



Thanks, Ben.



Thanks, Steve.

Excellent data and processing.

Am pleased to see you back from your break Rick.

Spectacular Rick! My better half really likes this image too :thumbsup:

I may yet one day convert and try astro-imaging with a reflector...

Love this object, and that's the best I've seen of it too.
Top shelf stuff Rick. Quite faint and a challenge to process from memory.

Do you have a rig at Martin's Yass set up now too? (cue green envy emoticon!)

Hi Rick,
That's a spectacular picture.
I my opinion it's better than 2 APODS I found.

Only a closeup - Hubble APOD shows more of the core:

:bowdown::bowdown::bowdown: Absolutely outstanding Rick!
I've come back to view this a few times over the past few days and I think it's a benchmark image for deep space imagers to aspire to.
Very well done indeed!

Thanks, Rodney. Roll on retirement when I'll have time to travel and to process all that data :lol:



Thanks, Suavi and Mrs Suavi! That's close to heresy from a confirmed refractorphile :D



Thanks, Rob. It is a difficult object but great data helps. The gear is Martin's but watch this space. Setting up in Chile :thumbsup:



Thanks, Allan!



Very kind of you, Andy.



Thanks, Martin.

The IIS thumbnail doesn’t do it justice...the full size is a must-see.

Nice Rick, real nice. Detail in the galaxy arms is excellent. Like I said I have been collecting data on this object for a few years. I will most likely need to start collecting again next year. I just did not get to it again early enough this year. I hope I can get something similar to this image, but Martin's CDK is a lovely scope and I doubt I can get mine looking as sharp as this image.

No criticism at all, as perfect as can be. How many nights was it captured over? The seeing there is very good too I imagine.

RickS
21-08-2018, 08:48 PM
Thanks. Data captured over approx 14 nights between 3 June and 2 Aug. The AO unit certainly appears to help with the resolution.
