Trifid in near infrared

[Stevec35]

I hope people aren't sick of these infrared postings because here's another one. It's a fairly short exposure of M20 which I managed to get before the sky clouded over. I may go back and get more data. Perhaps it looks a bit like a technicolour yawn but the same deal applies - reduced nebulosity and more stars visible. There are also indications of other dust lanes that you don't see in visible images. It's difficult to validate these images because there don't seem to be any colour images covering this wavelength. The only ones I could find were the 2MASS ( 2 micron all sky) images and things start to look quite different when you get to 2 microns.

Anyway here it is

Keep 'em coming, Steve. Nice to get some different views of old favourites!

[Stevec35]

Thanks Rick. I think these images have value because they are a "bridge" between visible and infrared where you can still recognize the visible nebula. Long wavelength IR images often look really weird.

It's very bold and contrasty. Keep them coming.

I'll try

The IR gives a very different look to these well imaged nebula :)

[Stevec35]

It varies. Some objects look almost the same. You get the most interesting results when there is a lot of dust present.

Good one Steve. A new look at an old favourite :thumbsup:

[Stevec35]

Thanks Rodney

Nice work Steve. I rather like this one, gives a really interesting twist to this icon. If you could get the resolution a little higher (I suspect seeing is the culprit) I suspect it would likely take on a Hubbleesque appearance :thumbsup:

[Stevec35]

Thanks Peter. Actually I thought the resolution wasn't too bad. The famous star formation spikes stand out fairly well. Bear in mind that you are going to get slightly enlarged stars with IR because of the longer wavelength.
