Comet Linear Images

Comet Linear will be the brightest comet since Comet Hale-Bopp, so there is a lot of interest.  Early on it was immersed in the morning twilight and for me the light pollution of Wash DC.  The track of the comet is shown above in the Megastar screen capture.  The circles show  the comet's position at UT=0.  The time increment between each circle is one day   Note that during the last week of July 2000 the comet approaches the Big Dipper.



 
 
 
 
 

This was my first image of Comet Linear.  It was taken when the comet was immersed in morning twilight and Wash DC light pollution. 

Scope:  8" LX 200 SCT
MX - 5C CCD
Focal Ratio:  f4.6 
Exposure:  120 sec 

This is a wide field of view of the comet taken with my 35 mm camera through the Orion MAK 500 telephoto lens.   The nucleus of the comet is just visible at the tip of the arrow.  At the time the photo was taken, it was about magnitude 10.  The image was taken just before I created the sequence for the animations with the MAK 500 riding piggyback on the LX 200 as always.

Comet Linear C/1999 S4 Animations   On 3 Jul 2000 I obtained a few images of the comet and created a GIF animation.  The animation shows the comet moving against the background stars and in front of a small grouping of three stars.  All three animations are the same.  I've just shrunk the image resolution to generate smaller file sizes.  Of course the large file shows the comet the best.

This image is a composite of two two minute images taken with the STAR 2000 Autotracker and ten 15 sec untracked exposures.  The  comet was moving so fast and my background sky was so bright that I had difficulty getting the STAR 2000 to track reliably.  Based upon my FOV & pixel count the comet was moving in right ascension at the rate of about  0.16 arcsec per sec when the image was taken.
