Ron Wodaski suggested this was a psychedelic crab.
In reality it is just a Crab shot through [SII], Ha and [OIII]
filters.
It has a very odd appearance though: another one
that looks very very different through these filters.
I was only able to shoot one exposure of 45
minutes through each of the three filters. I hope to be able to get more data in
the near future. We also had some light fog rolling in and out during the shot,
so there's a bit more sky glow than I would normally expect.
I used my C14 and shot this at prime focus which
works out to be around f/12.46
