(Left ) - C8 with un-cooled Mintron - 1/2 B/W ccd and a electronic video finder 75mm f1.4 Watec-902H. Note the 3 inputs/1 output video switch.
(Right) Deep Sky Object Indoor - I pumped up Mintron 12V1C-EX to max integration ( x128) and the Eta Carina keyhole Nebulae filled the monitor. - April 25 '04. The monitor was dotted with felt pen to mask out ccd's dead pixels.
Apr 27 C/ 2002 T7 Linear with bright condensed core. There is a faint spray of tail directed upwards - [Mintron x128 overexposed the comet core.]
No telescope needed!!
Portable Comet Setup: x1 Mintron 12V1-EX, x1 Watec-902H, 2 video lens of choice, 1 miniTV monitor, 1 Sony video walkman, RCA cables, a fixed tripod, 12 volt sealed acid batteries and a dash of eagerness.
May 12 '04 - Wednesday - Arrived at the field around 8pm - big chunks of slow moving clouds were obscuring the comet. Even at this early hour dews were starting to form on the lenses. I resorted to using my shirt to dry the lenses. Cloud thinned 9pm + and Neat reappeared bright competing with beta Cnc -- a magnitude 3.53 star (see map above - 2nd date stamp tick for 12 may). Before I packed up after 9:30pm I recorded a short sequences on 'beehive' in anticipation of this May 15 drop- in by Neat.
(Right Image) May 13 '04 - Thursday Sky condition similar to last night. The faint cone of comet's tail can be traced to 27 Cancri. Dimmest star ~ mag 9.6. A handful of passers-by joined the fun.
In later years i fitted a Mintron 12V1 to a russian 300mm lens for a closer view. The set up is still portable.
