Iris, and I'm sort new to this brown stuff...

[perfrej]

This is my first venture into brown stuff. I have had my TEC-140 collecting some Iris photons for the past week or so, and here is a first processing attempt. Difficult stuff...

43 x 15 min lum binned 1

85 x 5 min R binned 2

63 x 5 min G binned 2

73 x 5 min B binned 2

10Micron GM2000HPS, TEC-140, QSI-683, Astrodon filters. Capture with ACP, everything unguided.

My own comment is that I need to learn how to preserve and fiddle star colour, and also to stretch better.

Looks a bit better than my DSLR version

wow, that is a lovely image you have there, and unguided as well!

[StuartJPP]

Looks pretty good to me Per, especially unguided. I love the dark stuff and always come back to the Iris...now that I have got a mount that I can get consistent long subs with (albeit guided) I will be revisiting this target.

What was your sky like when you imaged this?

[ultranova]

Very nice, the large version is a must see,

There are several small Galaxies in the background that

I have never seen before,

A wonderful job on the Brown stuff.

Thanks, guys!

The sky is as almost always at Les Granges - pretty good! 

I shall pursue more of the dark stuff this autumn, for sure

Very nice image, especially at full resolution. Lots of interesting detail. Thanks for posting.

[Mr Bergman]

Nice image Per! I am also struggling with starcolour and also starbloating....

[laser_jock99]

Good effort- the core always gives me trouble!

[Tom OD]

Great shot per. The dark stuff looks pretty smooth too, good job getting lots of data for this.

Very nice image, the full res is great!!

A remarkable début in dust, Per! Firstly the noise is very low (plenty of good subs.) The general colour balance is convincing and you're starting to get those pinkish tints in the blue region which are a genuine feature of this target. Lovely!

Regarding the stretch, I do think it's a little flat and using a layer for the core might help resolve the central star. I'm sure it will be in the data. What about a dose of LHE? When I do it I take the result into Ps (Don't tell Harry  ) and use it as a layer, keeping or losing it in different places.

That is very nice

[perfrej]

Thanks,

Yes, Olly, I will fiddle some more with this eventually. The data is reasonably good and I feel I probably can lure something out of it.

And then you need to take a look at the Praying Ghost next door. Now that really is an object! (For something that's invisible...     )

A very fine Iris there Per! Lovely blues :-)

Olly, will do...

Chris, thank you!

Hi

That's starting to look very nice

A little to much purple to me --IMO of course

I agree with olly a little flat and LHE would help , but none of that layer nonsense is required

Hehheh. Life without layers would like life without... layers!

I just wish Ms Pixinsight would do it with Mr Photoshop... 

Harry, are you in possession of a fully calibrated monitor? I have one and there is no purple...

/per

[harry page]

Hi

Yes I use a spyder ?? not redone it for a few months though

I will recalibrate and see if its me

Keep well

Harry

[perfrej]

OK... Purple... Don't know... Maybe... Just a little tiny bit, perhaps... Hmmmm... 

/p

[ChrisLX200]

Can't see any purple either on my nice new 4K Dell monitor :-)

[ollypenrice]

No purple for me but this target does contain pinks mixed in with the blues. I don't know if this is Ha or ERE. Not all images find it but good ones do, for sure. Have a skim round the net. WIth the same scope this is what I found. https://ollypenrice.smugmug.com/Other/Best-of-Les-Granges/i-Dkk68fj/0/O/IRIS%20GHOST%20sRGB.jpgThe pinks are real, I'm quite sure of that.

Actually, there is a slight hue. I have just LHE:d it and done some adjustments, but the more you fiddle the more you loose control of the initial feeling.
