M1 Crab nebula at 1960mm FL.

[wavydavy]

Hi there, starting to get somewhere with my C11 HD Edge. On the 22nd got this one of M1 Crab nebula, in h-alpha. Used the 0.7 focal reducer, bring the FL to 1960mm. The camera was an Atik 314L+ mono. The filter was a baarder 7nm. The mount was a Ioptron CEM120, guided off axis with PHD2.

Forgot to add..........12 x 8 mins subs.

That's nice and I think you just got the pulsar too.

I rotated your image to match the reference (https://noirlab.edu/public/images/noao-03036/) and indicated the position of the pulsar:

Yeah I saw that on my data, should maybe of marked the pulsar, but didnt in the end.  was having a slight dew issue forming on the corrector in the end, so was lucky to get what I did...........

Amazing the detail can be taken with an 11"  if you  compare it with a 1950  image from Mt Palomar

Thats a great image, especially at that focal length.

Guiding / tracking must have been excellent.

Where did you take this from and what were the sky conditions like?

I took the image near rochester in kent. The sky was ok at the time, think there was some moon glow though. Its much harder at longer focal length than im use to, moe scrapped images then keepers! Dave.
