Hi Mark;
Glad to hear it's working for you.
Your also going to have to connect up two pins (Pin 0 and Pin 1)on
the "Rat Tail" GPIO connector for the Fleas cameras, and then check
mark the ""Allow extended PGR cameras exposure times. " (see page 61
of the Astro IIDC manual). That's how you can get exposures to 60
minutes with it.
Where I am now, the out door temp is -30°C or lower, so I don't need
any active cooling at all, but I do need an electric blanket on the
back of the LCD of the Laptop or it freezes solid and stops displaying.
TTYL..

Hi Milton, Thanks for your help choosing the parts for the peltier
cooler set-up. As you may
have gathered I now have the Flea 2, heatsink/fan & power source &
am awaiting the cooler
itself. I`ve posted a photo to my "set-up C9.25XLT OTA" folder in
photos to give you an idea
of the comparative size of the parts. I`ve also added a new file
with my latest mosaic done
with the Flea 2. Will maybe investigate further processing options
for the images. Interesting
that you were able to synchronise so many different nights' imaging
in your recent Messier
52 image. I`ll hopefully soon be coping with some DSOs myself. Have
a nice Christmas! Mark.
