Ngc1365

[Ryderscope (Rodney)]

Great detail, great colour and excellent PI processing.
Definitely a winner

[Paul Haese]

Very nice work Ray. Great colour and detail is crisp too.

A fabulous image with great colour and detail but on my monitor there is some weird mottled background blue artifacts like the blue channel has been pushed too hard. My laptop monitor tends to run a bit bluish as well.

Greg.

That's perfect Ray,
you encourage me to get out there with my 10" f4 Newt.

cheers

Hi Barry - hope you get some good sky.

Hi Paul. thank you for the feedback

Thanks for the feedback Greg. My monitor does not show anything much in terms of background, so maybe time to trade it in (or trade in the ancient eyes).
I desaturated the background a bit - did that help? http://www.astrobin.com/full/229192/0/?real=&mod=
alternatively, selective spatial filter?: http://www.astrobin.com/full/229347/0/?real=&mod=
Grateful for further feedback - of course I didn't have enough data in the first place, so everything was pushed fairly hard

Thanks Allan - how is the Newtonian project progressing?

A great shot Ray this is one of my favourite Galaxies to view.

Hi Derek. Thanks very much . yes it is a really attractive galaxy - it was a real thrill to see the data coming up on the screen.

Hi Ray,
It's going very well.
I just need the time & the weather to be on my side.

cheers

Im only on my samsung galaxy about to board the new p&o pacific aria in brisbane so was gunna wait till i could have a good look at it on a proper screen but meah, couldnt wait had to comment ....Excellent 1365 that Ray.....nup that's all
Mike

[rustigsmed (Russell)]

yep that is a beautiful shot Ray.
love the star and galaxy colours plus all the background galaxies.

cheers

[andyc (Andy)]

That's a top quality shot Ray, I'll be impressed if I see a better one this 1365 season (mind you, with some of the wizards here...). The swishy bits of the spiral arms are reminiscent of those Comet McNaught shots with the big curved tail, and you can get lost in the details of star clouds and clusters in the galaxy. Rich and vibrant colour too, lovely! I see the blue mottling in the background too, but given my standards on colour correcting wasn't troubled at all, I'd love to get colour as nice as that!

Might I ask how many and what length subs you used - I saw all the other technical info at astrobin?

[gregbradley]

The desaturated background is a lot better, the spatial filtering (what is that?)
is the same or worse. Its a mottled blue noise almost a pattern noise.

ahh ok I can see it, I have two monitors at work, hardly visible on one screen visible on the other. kind of like a diamond pattern wired fence has... If I was using PS i'd probably select shadows and turn the middle blue channel slider down 3-4 points. but yep I didn't notice it really till I went looking for it. still an amazing image!!!

thanks Andy. yes it does look a bit "comet like" - it is a very attractive galaxy. subs were 5 minutes for 1x1 lum and 200s for 2x2 colour. I had about 4.7 hours of lum and 3.5 hours of colour.

thanks again - yes, I can just see the blue mottled background on my netbook, but not on my 23inch monitor. In the process of sorting it out.

Greg, for the selective spatial filter, I decomposed the image into RGB channels and applied a masked wavelet filter to remove the dominant low spatial frequency components of the speckle in the blue channel background. I cannot see any significant change in the recombined colour image on my monitor, but it looks like the process upset other aspects of the colour balance - won't use it again.

Very nice Image Ray, looking stunning actually - beautiful sight

[graham.hobart (Graham stevens)]

A fantastic view of one of my favourite galaxies. Exquisite as always Ray!
Thanks for the view!

Gooday Ray,

Excellent image mate the best I've seen of NGC1365.

Co-incidently my latest copy of Sky and Telescope arrived today and has a 3 page article on this galaxy, and the ESO photo they provide is not a match on yours. Their image is all washed out with very little colour, you should send ESO a copy of yours and tell them "this how you do it".

Some facts about the galaxy I did not know
At 52 Million light years away it is one of the closest of the Abell Galxy Cluster S373.
It is twice the size of the Milky Way, 200,000 light years across.
The super massive black hole in the centre is 2 Million solar masses and get this, the black hole is spinning at a rate of 84% of the speed of light.

Cheers
Bill

P.S. My 60in HDMI TV/Monitor showed no blotches at all

Thanks very much Bill. thanks also for the great info - prompted some interesting reading. Sure is staggering to imagine what that black hole means. 2 million miles across, 2 million solar masses and as you say, an event horizon rotating at nearly light speed and dragging the local space along with it - unimaginable!!!
thanks also for the monitor feedback - seems like some can see a fault, others not, so I will have to adjust my processing to make sure that it is not an issue for anyone.

regards Ray

Whoa, excellent!. You must be using the cheat feature in PI

thanks Fred. Nope, no cheating here - where would be the fun in that?.
