Skywatch Mariazell, July 19th - 21st 2004

Puerahoefen - Bucklige Welt - Austria

On July 19th, after 3 month not using the observatory in Mariazell, my wife and i travelled to Mariazell
for 3 astronomical nights. From the weather point of view 2 nights were
excellent, one was only for having drinks and fun. The astronomical observations happened in the observatory of the "Astroteam Mariazell".(see
also at
http://ccdeder.freewebspace.com/index.htm).
This time i could first time use the new paramount mount together with the
new Canon 800mm 5.6 APO. I was impressed by the tracking quality of the new
mount as i could do all astro-imaging (up to 8 minutes) unguided! Also i was
impressed that we (Walter Simotta and i) opened the observatory, switched on
the PC and the mount, entered "goto Merkur" and the object was
really exact in the middle of the eyepiece in the 16" LX200.
As a first test of the 800mm Canon lens the 55 hours old moon was a good
target for learning focusing with the Canon 10D.

As these days the comet C/2003 Linear K4 stood high and showed 2 tails it was a must to capture
K4.
Here the results of imaging the comet on 19th and on 21st. On the 21st the tail
of the comet was
already very faint.
