1377014 hours 20 minutes, AP 140, PMX tuned to perfection with T-Point and it paid dividends with superb tracking.

Lovely result, Greg:thumbsup:

Absolutely beautiful, Greg ...
:thumbsup::thumbsup::thumbsup:

Greg, that's the best image I can recall seeing of that nebula! You've got everything working very well.

Thanks Larry. I was happy to get the PMX singing. It allows the AP140 to shine.



Thanks Ian. I was happy with the result as well.



Thanks Chris. The tracking was one of the best I have ever achieved. It was very accurate. Plus the seeing was good.

Great looking photo Greg.

So sharp and detailed.

I got to Coonabarabran last week for a couple of nights and managed to get a few photos of it as well.

Great image, loads of fine detail. Looks like your setup is paying off.

:thumbsup:

[gregbradley]

Thaks Ross. Coonabarabran sounds great. I took a few DSLRs snaps there once , nothing special. Its quite high altitude there so I am sure that helps a lot.



Thanks David. Yes the mount, scope and autoguiding were working really well which makes imaging a lot easier.

Greg.

Super image Greg!

Dunno Greg. I don't understand what is happening with the blue reflection nebulosity. I know it extends a distance from the main structure but not as far as you present it. Its hampering the murky dust behind it. Did something go wrong?

[Rigel003]

Lovely image, Greg. Nice wide field too.

[TrevorW]

Yeah nicely done great colour

[allan gould]

This is my favourite nebula as there is so much in it and your photo just re-inforces it. Thanks for posting

Cheers, thanks for that.



I checked the data again and there does not appear to be any mistake. That's the data. Its taken from a totally dark site with a top line refractor uinder good seeing using a very sensitive camera with perfect tracking and thats what you get. It does extend that far. I know what you mean as I was surprised by how far it extended but there is no odd processing here. In fact the image has had very little processing which is my preferred style.
Just ideal conditions brought it out. Its not the first time I have picked up more extended reflection nebulosity from my dark site. Its nearly perfectly dark there.



Thanks for that.



Cheers trev.



It is a very aesthetic area. The little glob just adds to it

Hi Greg,

That's undoubtedly stunning, amazing work.
But do you think the stars are a bit stretched?
just my opinion and this is just aesthetics, they seem to dominate the image more than the beautiful nebulosity, and I can't make out different star colour when compared to others like at apod. is it because its a wide FOV? The core of the Glob shows up a blue hue in a histogram.
this is one http://apod.nasa.gov/apod/ap060403.html where there are quite a few yellow stars, but then the glob has a yellow hue.
what should it ideally be?

Cheers
Alistair

I am with Jase here. The blue looks monochromatic. :shrug:

[gregbradley]

Thanks Alistair for the link. On checking further I found an error in the green master. It had a few dodgy subs in it that I missed. Cloud affected and it threw the green off. I've redone it and its correct colour now.



Yes you are both right there was an error. Thanks for picking it up.
Repro posted, same links.

Cheers Greg.

[tilbrook@rbe.ne]

Stunning Greg!

Some beautiful colours through the image, stars look great.

Cheers,

Justin.

[gregbradley]

Thanks Justin. Its a great area of the sky.

I've added a cropped image as well now.

Greg.

[Paul Haese]

That looks very nice now. I like the subtle shadings now.:thumbsup:

[strongmanmike]

This is being imaged again already...??? man, where did that year go :question:

The first version was ummm? i-n-t-e-r-e-s-t-i-n-g...:question:

So, lets forget that version...:thumbsup:

This latest version is quite good, can't help but think it seems to lack a little sharpness/resolution :confuse3:...have to say though, the dust and reflection mix is just about the finest in the sky huh?! :eyepop:

Nice work

Mike

[gregbradley]

Thanks Paul and thanks for the tip.



:lol: funny post. I tried just then to sharpen it more and it won't take it. The TEC180 would give more rez on this. Or more data with the AP140.

Yes its a great object. I'll probably add to this next time.

[strongmanmike]

Yep, that's me, King of funny posts... :question: :help:

:lol:

[naskies]

Nice work, Greg! Really nice star colours and I like how the dust looks 3D.

[gregbradley]

Thanks Dave. This AP140 scope is an amazing scope and it does everything very well.

I am doing a narrowband series with it now. The PMX is humming - 20 minute subs round stars - no worries.

Greg.

[David Fitz-Henr]

Great work Greg; love the colours!! I have yet to collect all the RGB on this one so your image will be great to benchmark the colour processing against - it looks beautiful!

[gregbradley]

Thanks David.

I look forward to another spectacular Bunyip Production.

Greg.

[Peter Ward]

The AP140 is working well for you. Nicely done :thumbsup:

[gregbradley]

Thanks Peter. The AP140 is an amazing scope. It just does its job perfectly. I wish all my gear was as perfect as this.

Greg.

[LucasB]

Another fantastic image Greg. Looking forward to your next project.:thumbsup:
Lucas

[gregbradley]

Thanks Lucas!

As a matter of fact I just finished processing the next one! Just doing the "cooling off period" to see if I still like it
tomorrow!

Greg.
