Lagoon and Trifid area in near infrared

[Stevec35 (Steve)]

It's been a while since I've used the Astrodon near infrared filters and I thought a FSQ shot of the Lagoon and Trifid area would be nice. The composition is a bit unusual I suppose but I wanted the maximum attention on the Lagoon.

Cheers

Steve

Thanks for that view Steve, really unusual.

No problem Allan

Very interesting Steve, and amazing how half of the Lagoon just disappears in IR.
I've thought of getting the NIR filter set, but I don't think it comes in 31mm unmounted for the QSI? I really must look into this again. Thanks for showing this inspiring image.

Great shot Steve.

Shows lots of detail.

Unusual and nice.

Thanks Rolf. It's certainly a different look. Unfortunately you are correct about the 31mm filters. I just checked the website and the filters are only available in 1.25" and 50mm.

Interesting Steve.

Here is an animated gif of your image and one of mine in visible 4MB

It really shows the differences.

Thanks Bert - it certainly does bring out the difference. I did a similar thing when I shot M8 in IR through the RC.

very interesting. I note some stars look so much brighter in IR, no doubt the cooler ones, or rather cool stars with atmospheres blocking shorter wavelengths.

Certainly IR puts a new light on things. Generally the longer the wavelength the less objects look like they do in visible. Spitzer shots of the Trifid have the dust lanes looking bright

Ah huh! who's got the IR filter out again looking for more undiscovered globulars, huh? ...nice article in AS&T too by the way.

Cool shot...Good luck

Thanks Mike. I think it would have to be a pretty big globular to be visible at this focal length but you never know.

Yeah it's a pity. But I'm getting a Clear filter soon to compliment my L filter, and I figure Clear minus L should give an IR/UV view, so at least I can try that.
