Hey guys, haven't been on in ages since switching jobs/new business. Made it out last night, and it was nice to see the night sky again!

24x8 minute subs with the QHY10 and RC10.
A little more background noise than I was hoping for, but I think it looks good.

I think it looks good too!

Lovely golden-silver globular cluster image that Erik! Beautiful.

A very pretty glob, Erik!

Hi Erik,
Nice data.
I hope you don't mind?
I boosted it with LAB colour.
Is this better?
There seems to be a population of yellow & blue stars.
I thought globs were mostly yellow?

cheers

Nice one Erik, and it makes a pleasant change from the usual GC suspects.

ps - what have we done to get four consecutive clear nights here in Gippsland?

[E_ri_k]

Thanks everyone :)


Not at all Allan, that looks much better, I thought it may have been lacking a bit of colour in the stars. I think they are mostly yellow, however contain a few blue stars.


Thanks, yeah I know right, the weather has been pretty unstable recently.

Hi Erik,
it's amazing what a little boost of LAB colour can reveal that's hidden in the data.

cheers

James Dunlop was the first to see this object, from Parramatta in 1826. He didn't know what to make of it.
The longest description in his catalogue was his description of this object.
"Dunlop 67. A star of the 6th magnitude, with a beautiful well-defined milky ray proceeding from it south following (SE); the ray is conical, and the star appears in the point of the cone, and the broad or south following extremity is circular, or rounded off. The ray is about 7' in length, and nearly 2' in breadth at the broadest part, near the southern extremity. With the sweeping power this appears like a star with a very faint milky ray south following, the ray gradually spreading in breadth from the star, and rounded off at the broader end. But with a higher power it is not a star with a ray, but a very faint nebula, and the star is not involved or connected with it: I should call it a very faint, nebula of a long oval shape, the smaller end towards the star; this is easily resolvable into extremely minute points or stars, but I cannot discover the slightest indications of attraction or condensation towards any part of it. I certainly had not the least suspicion of this object being resolvable when I discovered it with the sweeping power, nor even when I examined it a second time; it is a beautiful object, of a uniform faint light. Figure 2"

Nice quote Glen. Added a repro version, using Allan's tip with the Lab Colour. How does it look? Is the bright star too blue? Background is a bit smoother I think.

Looks a lot better Erik,
I used a partial mask on the background & the bright blue star -
when I boosted the colour -but it wasn't really necessary.
I love LAB mode now - you can boost colour without changing brightness.
You have great resolution on that glob & an image to be proud of.

cheers

For anyone following this thread who doesn't know how to use LAB mode:

I found out about it from Louie's video here:

His whole series is here & I think they are all essential:

Cheers Allan, yeah I had to do a search on how to use Lab Colour! I must say I like it a lot, a great tool.

Might have another play with some masks.

Nice Target Erick, your 2nd is much more dynamic in my eyes, the colors are much betterra, particularly the stronger golds, I think golds in Globs realy set them off, A beauty of a repro :cool2:

[Carmen4594]

Gosh that is very pretty indeed Erik.

Great capture.

Carmen

[atalas]

Very nice work Erick...looks way better with the LAB boost.

[Stevec35]

It certainly does look good. Nice work Erik.

Steve

[prokyon]

Very nice, like golden pearls! Woderful!!

[dvj]

Stunning! The 3D effect is excellent.

[gregbradley]

That's very nice. I think the goal in processing these types of globs is to get those golden stars to sparkle and highlight the image.

I think you achieved that quite well.

Greg.

Beautiful image, well done.
:thumbsup:

[ericwbenson]

Hi Erik,

IMHO I think your first attempt had better color balance as the saturated bright stars were white in the center as they should be. In the latter attempt all the brighter stars are washed with blue as are their halos. While the contrast in the colors of the fainter stars is good, the brighter stars have suffered. I do agree the bgd noise is better in the second, as is the bgd color which is closer to grey than the slightly yellow original.

Best,
EB

[alpal]

I don't agree with you.
I did a LAB version - further down the page & it looks nothing like what you're saying.

[jenchris]

Love the intricacy of the glob - beautifully captured like a ball of glitter

[rcheshire]

Too good... a clump of stellar jewels.

[multiweb]

I'm not one for clusters pics usually but this is a great shot. Love the star colors and definition. Well done. :thumbsup::thumbsup::thumbsup:

Oh, that's a true beauty!
Diamonds on velvet... Sheer delight!
