detail in the Humunclous Nebula in infra red

Hi all
With skies clearing and the moon bright, I used my infra red pass filter on the star Eta carinae. Filter passes IR light from about 800 nm and longer
6x8 secs ISO200. Modded 350D. 10 inch f5.6 newtonian. Drizzle in Iris used to double image scale.

It's very interesting that you can actually see the star. I wonder how a HDR technique would work combining luminance with IR.

Here is an animated gif I made from your IR image and a HDR image I made with the TAL200K of the Homunculus. Seeing was lousy. Not one of my visible images showed any detail but the HDR did as there is a huge dynamic range in this object.

Scott as you can see your resolution is far better. I think with a series of sets of exposures in IR doubling the length of the exposure each time would make a very nice detailed HDR image in IR. I would be willing to produce the HDR image .

Below is the Hubble image at about the same orientation.

Thanks, yes I will try that when I can. HDR might suppress the star and allow even more detail to come.
