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?
