Hb 12 Visible + Infrared

While trying to write an article regarding the Hubble archive today, I revisited this object and decided to process it again. Previously I used NICMOS data for the infrared part, visible in orange as the slightly blurry-looking rings and arcs around the brighter central structure. The old version is here.

 

I think the new version offers up a somewhat clearer vision of the infrared portion. NICMOS was always a bit difficult to work with because there were a lot of "features"—as they have been charitably called—to work out of the image. This version uses observations made by the newer WFC3/IR, and I am a lot more confident that every little faint detail you see here is indeed the nebula and not some instrumental wonkiness.

 

I removed the diffraction spikes once again because they were very distracting and easy to confuse with the structure of the object.

 

Data from following two proposals was used to create the image:

Characterization of the WFC3 IR Grisms

Hubble Heritage Observations of PNe with WFPC2

 

Orange: WFC3/IR F140W

Green: WFPC2 F658N

Blue: WFPC2 F656N

 

North is up.
