Here's Eta Carinae taken with the Astrodon near infrared filters. Not exactly visually appealing but it does show some interesting features. Reflections have messed up the area around Eta a bit.
Place your mouse on the image to see a mouse over with some (not very good) HaRGB data I had laying around.
Cheers

Looks OK Steve but I still much prefer your RGB version.

Cool image.
Looks like the IR is wreaking havoc by way of internal reflections....none the less you are pushing some interesting boundaries with amateur imaging.
I for one would like to see some more :thumbsup:

Thanks Peter. Yes the internal reflections are a hassle so keeping away from bright stars is worthwhile. I've only got one more target in mind before I switch back to the visible but you never know what will come up.
Thanks Doug. I agree that the RGB looks better but I guess I'm not after visually appealing images here. I just want to show how some objects look in less familiar light.

Pretty interesting Steve.
I like the way the infra red filters cut through the dust and reveal stars that aren't really seen in the standard filtered view.
Might have some really interesting applications with certain objects.
All the best

Thanks Rich. I'm still feeling my way with these filters but I think their best application may be in seeking out obscured globular clusters and galaxies.

I think it is interesting how in the infrared image there is what looks like shells of gas concentric about Eta. Not seen the in RGB image. Incredible really. Nice study Steve.

Thanks Paul. I think what you are seeing are reflections fom Eta. The CCD camera is optimised to minimize visible relections but not infrared. I think I will be staying away from bright stars in future when doing infrared.

Oh well, it is still interesting all the same. It just coincided with the arching jet coming off the Key hole. I just thought that might be the case from the previous Nova event in the 19th century.
