Comet C/2001 Q4 NEAT

Comet C/2001 Q4 (NEAT)

C/2001 Q4 (NEAT) 2004 05 19.4, 260 second exposure taken with a Nikon D70 digital camera and 85mm lens @f/2 showing the comet as it recedes from Earth and the Sun.

C/2001 Q4 (NEAT) 2004 05 16.3, sum of 4 30 second exposures taken with a Nikon D70 digital camera and 85mm lens @f/2 showing the comet next to the Beehive Cluster in Cancer

C/2001 Q4 (NEAT) 2004 05 11, taken with an 85mm lens @f/2 and Nikon D70 digital camera. This sum of 10 X 30 second exposures shows approximately 10 degrees of tail.

C/2001 Q4 (NEAT) 2004 05 06.35, GRI tricolour image made from 3 X 15 sec Green, 3 X 8 sec Red, and 3 X 12 sec Infrared filters, represented by blue, green and red respectively here. North is up in this 16' field. The image brightness was scaled to represent the overall appearance to the eye through a large telescope.
Taken with a 45cm f/5.4 Newtonian, + AP7 CCD from the Gene Shoemaker Planetary Society NEO grant, from Loomberah NSW Australia.

C/2001 Q4 (NEAT) 2004 05 06.36, sum of 50 X 10 sec exposures through a red filter, FFT processed to reveal complex inner coma structure. North is up in this 15' field.
Taken with a 45cm f/5.4 Newtonian, + AP7 CCD from the Gene Shoemaker Planetary Society NEO grant, from Loomberah NSW Australia.

C/2001 Q4 (NEAT) 2004 04 25.44, GRI tricolour image made from 2X30 sec Green, 1 X 30 sec Red, and 2 X30sec Infrared filters, represented by blue, green and red respectively here. North is up. The image brightness was scaled to represent the overall appearance to the eye through a large telescope.

Comet NEAT

C/2001 Q4 (NEAT) 2004 04 24.39, sum of 5 X 20 sec exposures, FFT processed to reveal near-nucleus structure. North is up in this 9'.5 X 14' field. Visually, the tail was visible to over 5 degrees in 10X50 binoculars Taken with a 45cm f/5.4 Newtonian, + AP7 CCD from the Gene Shoemaker Planetary Society NEO grant, from Loomberah NSW Australia.
