Hi Tim;

For the Flea camera, you need to connect Pins 1 and 2 on the included  

round Hirose HR25 Male 8 pin connector. The connector has 2 sets of  

pins on it, the very fine ones that fit into the back of camera  

socket and the coarser pins on the other side that you will connect  

up. The pin numbers are shown in the PGR pamphlet that was included  

with the camera (see back page entitled "Camera Interface"). It looks  

like this:

N

P1

P2 P3 P4

P5 P6 P7

P8

The N is the "notch" in the ring, so you know how the connector is  

oriented. The P1 to P8 indicates the pin number. You connect P1 to P2  

and then check the "Allow extended PGR camera exposure times" item in  

the Astro IIDC Preferences, which tells Astro IIDC to implement a  

Bulb type mode for long exposures of up to 60 minutes.

Their is only about 1.5 mm of distance between the pins, so you can  

either drip some solder on them to connect them up (which is what I  

did) or bend them over so they make physical contact.

HTH..

Now that I have an SBIG camera that can autoguide my Tak and  

Nexstar mounts, I'd like to

take images longer than 60 seconds with the Flea on a Megrez 80  

piggyback on the main

scope.  I remember you once said I'll need to solder a couple pins  

together, but I want to

make sure I know which ones before I do that.  Is the info on your  

website somewhere, or is it

in the Pt Grey Documentation?
