IC4592 The Blue Horsehead

[gregbradley]

A very pretty object which is close to the Rho Ophiuchi complex. Its fine dust lit up by the bright star which is part of the Nu Scorpii star system (from an APOD). The dust reflects blue light best because the size of the dust grains matches the blue wavelength the best.

It also looks great with a wide field scope or a 200mm lens on a DSLR.

All I get in the HR version is: "must log in as gregbradley to view page"

[gregbradley]

Yep, sorry I had to check the checkbox to allow public viewing. Fixed now.

Looks great Greg - that RHA/sensor combo sure has a nice field of view!

[gregbradley]

Thanks Pete. Yes it does have a pleasing field of view. Luckily there are quite a few objects that it suits but its good to image with long focal length from time to time.

Nicely done Greg. An ideal object for the RHA.

Cheers

[gregbradley]

Thanks Steve. I agree its a good match for the RHA.

Really nice Greg, an interesting field! Looking for some wide field targets (120mm FL) for my next dark sky trip :) May just add this to my list.

[gregbradley]

Thanks Colin. NGC6726 is a classic and always worth some time. 120mm though would be too short, did you mean 1200mm?

Greg.

[Atmos]

Nope, 120mm. You did mention a 200mm so I figured there isn't too much difference... Relatively speaking. Unless you meant 200mm and therefore suggesting an 8" refractor ;) :lol: Just so happens to be near in size to that TOA you have!

[Paul Haese]

Its a huge object this one. You have captured quite faint nebulosity too Greg. Nice colour also.

Thanks Paul. Yes it is very large. It would suit the FSQ and 11002.

The "for Marcus" version is awesome :thumbsup:

[gregbradley]

Hehe, got a put a few in-jokes now and then to keep the forum lighthearted.

Glad you liked it.

Greg.

Looks good Greg! :thumbsup: I'd do some shadow highlight / other stretching to bring out the dust a bit better though. There's some nice brown stuff in there waiting to be appreciated.

[gregbradley]

Thanks Marcus. I'll check it out.

Lovely, Greg! Your new rendition looks particularly diaphanous.

[Andy01]

Very ethereal Greg, like a new brides veil swishing over the stars :)

[gregbradley]

Thanks Rick. I tried to keep the processing subtle.




Cheers Andy.

That's awesome Greg.
So much detail. Lovely binary in the middle.
Beautiful blues

Thanks very much Scott. It certainly is a beautiful delicate object and I am big fan of reflection nebulas.

I love it Greg- one of my fave nebs. :thumbsup:

[gregbradley]

Thanks Graham. Your Vela is shaping up nicely as well.

A beautiful closeup of the Blue Horse Head Greg.

Great looking colours and you have captured all the fine details.

So sharp.

Love it!

Cheers Ross. I am glad you liked it.
