Pan-Starrs is well circumpolar from here now and was some 2.5 hours from lower culmination during this observation; so pretty low down. Actually it would be going through our zenith (Lat.54.7N) around mid-day currently!

Its golden hue made a fine contrast with the blue-white stars near zeta Cas. Before some thin cloud cleared from it the comet looked almost square in the 12x65s!

Edit Note: I had neglected to reset Corel from printer to web optimisation; so previous attachment colours were off!

David,
This drawing is superb!I like the way you used color's with the stars in your drawing. Is this done with Pencil? I was able to catch Pan-STARRS a few weeks ago through my 72mm Refractor and it was a very nice looking comet.

Thanks Ken: I had lost touch with the comet when I realised that it is circumpolar now: and I cheated with the star field somewhat in that I printed the general field from Sky Map in black & white and used white pastel (stump-painted) for the comet on this and ‘corrected’ the stars to what I actually saw – spikes added for brightness effect. Then the drawing was digitally photographed and tinted in Corel Photopaint, similar to my planetary ones. I really need to locate my goodly stock of black cartridge as it’s too costly with black ink using this method! It was all in haste as the comet was soon to be lost behind trees and a large garage!

David.

David,
Interesting technique, I like the spikes in the stars and thought a bit about sketching the Pleiades with the spikes to show their grandeur.

I hope comet ISON will be able to put on a show for all of us this winter.

Thanks again for sharing your thoughts and techniques. I am always interested in learning more of sketching.

A beautiful sketch, thanks for the view. I just came in from viewing Panstarrs and could only see the brightest part of the tail with my 10" refl from light polluted skies.

Wow, David! Spectacular drawing with some sparkling colours which make the whole come alive. Did the comet really seem so yellowish to you? Very well done!

Thanks everyone for your kind remarks.

Peter: Yes I was struck by the "golden hue" (1st post -also in 12x65s)): could well be down to lo-alt 'reddening' tho' the contrasting blue type B stars seemed little affected. Perhaps we have something analogous to the double-star complementary colours phenomenon!? It was this colour contrast that inspired the drawing.

David.

Well, I love the colours in your drawing. Pity that the comet's behind my observatory now so out of reach because I'd love to see it again.

Cheers,

Peter
