Comet 2003 T4 (LINEAR) looking nice

Hi all,

Comet 2003 T4 (LINEAR) is looking nice at the moment. It's in the morning sky (in Sculptor) rising about 2.30am local time (from NZ) and has a nice photographic tail (at least 2 degrees long). It's definitely worth getting up and having a look / taking an image. The following are its positions for a few weeks -note that it's slowly fading:

The following are two images I took this morning (in poor transparency) - the first through my 16" f4.5 Meade Newtonian and the other through a 70-200mm Sigma lens with a 1.4x telextender (200 x 1.4 x 1.6 = 448mm @ f4).
