Mario has sent us two images of the Jellyfish nebula, IC443, a supernova
remnant near Eta Geminorum, at the foot of Pollux. The images can be seen
at the bottom of his gallery, here https://gaac.us/gallery-2/mario3/.
Mario writes that he "imaged this object with two different scopes, the 6
inch refractor for a wide-field view, and again with the 32 inch for a zoom
in to the 'head' of the nebula. Each image required 3 hours with Ha, O3,
and S2 filters."

The wide-field image is particularly impressive.
What filter(s) produced the dominant yellow hue, pray tell?

I used NB filters, 1 hour each. O3 was weak, S2 and Ha were strong,
combined using the hubble pallet

Unbelievable detail. What I find amazing is that these images have #D depth to them.

With the [SII] emission strong, that shows evidence of shocks in this
supernova remnant.
With the [OIII] emission weak, that shows the shocking to be less energetic
than in the Cygnus Loop, for example.

That makes sense, thanks
Not due to difference in element production then at all?
