ngc5139 - new and improved ;) with more photons

[h0ughy]

last week i took this during the full moon (http://www.iceinspace.com.au/forum/showthread.php?t=60451) so last night i added another 1.5 hours of data to the image by combining the two outputs through Pixinsight 1.6. Taken with the 127ED triplet, the hotech field flattener and the cooled canon 350D all in the doghouse - total time 2.5 hours iso 400. I am stoked with the result as this is really the best image i have produced by myself that i am happy with of this object. only up from here :rofl::P

EDIT: the repro of the image below is found here (http://www.iceinspace.com.au/forum/attachment_browse.php?a=75835)

[David Fitz-Henr]

[h0ughy]

thanks Paul

[h0ughy]

thanks David

[Hagar]

This one is a ripper David. Resolved beautifully right to the core.

Well done Mate.

[h0ughy]

thanks Doug, though looking at this in the morning it is still a tad to the red side - i can see a repro coming up:lol:

[iceman]

Nice work Dave, lovely tight stars. Seems to be a missing a bit of colour (especially some red stars) but lovely work all the same.

[h0ughy]

will be doing a repro - so what should the colour be?

[iceman]

I think there should be more red stars. eg:
http://www.atscope.com.au/BRO/gallery50.html

Now I know the equipment is slightly different, but the colour must be getting lost somewhere.

[h0ughy]

Mmm yep I think the equipment might just be slightly different ;) (SBIG STX16803. Self Guide mode. LRGB 10:15:10:15 mins, RCOS14.25" F7.9) about the only thing that I can get close to is the focal length, mine is f7.5. In this case the one shot is left holding the door….

[toryglen-boy]

Dave, thats a great image. well done, you must be stoked

;)

[Screwdriverone]

Gee, those blue stars really give it some depth Houghy,

Nice one!

Cheers

Great exposure and focus/guiding.

[h0ughy]

it is good to get the focus right - something i have struggled with for years. As for the guiding its hard to believe i had mega trouble with the 10" on the same mount - with the 127 on there i can get this result. No going backwards (or forwards?);)

[h0ughy]

that i am - -but will be reproing real soon to get the colours right

thats the thing that stood out to me - considering this is my real first decent go at this object - and it was done during a full moon (and slightly less ) i was amazed.

[acropolite]

Fantastic effort Sir h0ugh, the lack of colour certainly doesn't detract. :thumbsup:

[h0ughy]

LOL thanks Phil - Just for you i have rebutchered it - i will be having another go after this cause its horrible

[h0ughy]

I have now reprod or done another Sidonio......I used a function within pixinsight and applied a colour balance

[Screwdriverone]

Hi Houghy,

I like Post 20's pic (the second last repro) the most, looks DEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE EEEEEEEEEEP

Even nicer now...

Cheers

Chris

[h0ughy]

thanks Chris

[Lester]

Outstanding image David. Looking at the faint stars and seeing how many there are, makes me think that the actual globular may be far bigger than the bright consentration of stars. Thanks for the view.

[h0ughy]

Thanks Lester, quite a compliment:thumbsup:

[seeker372011]

:thumbsup:

[Jeffkop]

Spot on David. I actually prefer the very first image. Resolved beautifully, focus great and a natural looking balance with the blackness. No wonder yer stoked, I would be too. The doghouse scores a try !!!!!!

[h0ughy]

glad you like it


Jeff, thanks. see any mug can achieve something like this;)

[spacezebra]

WOW! Thats stunning David. It has the same 3D impression that I get from scope. Well done!

Cheers Petra d.

[h0ughy]

glad you liked it Petra:thumbsup:

[Enrique]

David:

Excelent work. I like the blue stars.

My case: I am loosing the color in the center of the stars in the raw images. How did you keep the color for the big stars?

Enrique

[h0ughy]

Thanks Enrique!

i do a background neutralisation and then a colour calabration within Pixinsight, adjust the histogram and levels then apply some colour saturation

[Harryianpage]

Hi

Very nice glob that :thumbsup: all pixinsight power to you

Harry

[h0ughy]

Thanks Harry:thumbsup:

[RB]

Excellent work mate, great to see everything coming together for you and all the equipment running smoothly !

You are the PixInSight master.

:thumbsup: :thumbsup:

[h0ughy]

Thanks RB - i hope to better this next month
