Cas A SN remanent 3C 461

[Davey-T]

Has anyone imaged this , I had a look for it last night with no luck .

There's an image on the CFH Telescope site but obviously taken with something a bit bigger than I've got.

I'm using 10" sct with 6.3f/r .

Have found out since that it emits in Oxygen and Sulpher but not Hydrogen apparently, guess I'll try again with O111 filter.

Interested to hear if it's possible to capture it or if anyone has or if I'm wasting my time.

Good question. Richard Crisp had a crack at it.
