I was stunned to see how bright it was even under a full moon and low in the north.
6x30 seconds ISO200. UV/IR filter, MPCC coma corrector. 10 inch f5.6 newtonian. Hutech Modded 350D, Off axis hand guided. Yes it really was that yellow too.

Fantastic Image Scott. It really looks like a huge fur ball. Congratulations. You set that up on the front lawn?

Thanks
Yep sure did. Looking over the brick wall, was odd to see the scope laying over so low pointing north. The comet was just so bright even in the vewfinder, but visually was hard to see the detail the image caught. In incredible object for sure

Wow :eyepop:

That is the first image I have seen that mimicked the colour I saw in my 15x70 binos.

I was careful to try and keep the colour balance as accurate as possible, by using the IRIS "white" command on the sky background (which was illuminated by white moonlight) thus keeping that neutral and seeing that in theory at least everything else appears as naturally coloured as possible even hopefully accounting for the fact the comet was fairly low.

It's disconcerting that it has no tail - maybe it's coming straight for us :scared:
Nice image..... especially from down here....

Thanks all
I did another imaging session with the same gear thismorning, getting it just as it was transiting. Still quite low, a southerly change had come through, the moisture making the sky quite hazy, and the seeing was quite bad, impossible to get a sharp focus on the stars, also some chromatic colouring due to atmospheric refraction on the bright stars as it was so low, but here it is.
13x30 secs ISO200 with the 10 inch scope.
Notice its got somewhat bigger, with the top left edge more diffuse then the lower right one.

Excellent image Scott! beautiful work.
Fantastic Scott.
Exciting to watch how it develops !!
Good shot :) it seems that the coma is coming to disgregate (smeared left edge) in a such of an atipic tail.
