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.
