Polar alignment, Vixen GP mount

Posted By David Held
Can anyone tell me how to use the polar scope on a GP mount?
there is a standard RA ring, then a inner ring that is divided in 12 then under sections 12 & 1 on the same ring
reads E 20 10 0 10 20 W . Then etched on the scope is an

offset circle for Polaris. up to now I have been just guessing about where the pole is from polaris but I would like to know how to set these ring's to the date and time for
polar alignment.

you can E-mail any info to me at [email protected]
THANKS Dave

Has any one tried to stack 2 or more of todays short barlows? would two 2x = a 4x ??
Or Would placement be a factor. and would there be other prohibitive reason for not doing this???

Geminid Meteors

Posted By David Held
Even with the full moon in Gemini I saw a lot of fireballs.
With the forcast so grim I had forgot about the Geminids and
was not looking for them. It was chance that I saw about 3
fireballs in 10 min. Really They could not have been missed
Did any one get a better count?

Posted By David Held
Hi James, You may have tried this but...
With my computer and camera I get that message
all the time and I must unplug the USB from the computer
and wait a few minutes then plug it back in.
Good luck, Dave
