Crab Nebula taken from Sidcup before the clouds rolled in.
22 x 5 min with modified Canon EOS 350D on Celestron C11 with F6.3 focal reducer. Astonomik CLS filter + IR filter.
Guiding with 300mm lens with x2 converter + modified Toucam.
Scaled down by 2/3 and then cropped.
There was a bit too much wind and the seeing was poor but I'm still quite pleased with the result. Ambient temperature 4C.

Here is the one I took this time last year at the December Deep Sky Camp:

What a difference in a year! The main differences are two-fold:
1) The camera is now modified (letting through more H-alpha)
2) Guiding means I can take 5min exposures instead of the previous 30sec unguided exposures.

I like that very much, Mark, lots of depth.
So many subjects on the horizon, for us, if the weather would improve!
very good mark, i'm going to have another go at that if i can this year my last one was not brilliant, maybe next week if its clear
Nice image, you can definatly see the change.

ha ha ha ha ha ha ha. :lol:
Fay can i have some of the drugs you are taking, wow you have some funny ideas. :lol:
see you this afternoon.
I'll be using all my drugs for today, Mac!!!!!!!!!!!!!!!
That's really excellent Mark - good depth and detail, it looks almost 3d. Could you do me a favour and bring your guide camera an lens in for me to look at, I'm looking at using something much smaller than the ED80 for guiding my refractor.
Fay - don't take all those drugs, keep some for me .... please !
I agree with Robert, looks very 3d, lovely definition, I was suprised this object was a lot tougher to image than I expected but you've captured it beautifully.
Excellent job!

:O)
Yet another wonderful shot from Mark, you never fail to impress.
A big improvement on last years image.

Mark - Excellent... Such an improvement... You are seriously making me think of tackling modifying my EOS300D... You get such great results...

The stars look slightly overblown but it is a really nice image.
