After seeing all the Camcorder talk I have decided to make a camera that is capable of the following: 1. Zoom and Focus via computer control. 2. Standard video via s-video 3. All camera functions controlled via computer What I came up with is a Sony FCB block camera. These are controllable via serial connectivity. The one I chose has a 1/4 exview HAD sensor. Its not extremely sensitive but should be enough for planetary. It also has sens-up, but not sure how much. The camera will be in-cased with a 32mm eyepiece to make it a plug and play. I already have the block camera and eyepiece. I just have to make an enclosure and do a ton of soldering I will post as I progress with this project.

I temp wired up the camera today, I was able to control most functions via the computer. So far I have confirmed the following works via serial to computer. 1. Gain 2. Shutter 1/4 - 1/20000 3. zoom 4. manual focus Still need to figure out a few other features, but I am close. Next is to mock up a temp setup on the scope so I can test. If everything works out, I will put it all in a nice permanent case. More about the camera These are core camera for nice expensive PTZ dome cameras. It contains a 36x full optical zoom with auto focus. Contains a exview HAD sensor. There are no interfaces on the camera, only ribbon connectors. Interfacing the camera is a challenge and not for the faint at heart. However, I managed find a ribbon cable breakout board that allowed me to interface the camera. This camera may only work for the moon, but that is fine. My hope is it will work similar to a camcorder, allowing me to zoom in close and personal. Hemmi

Also I got it off ebay for 65 bucks So not a huge loss if it does not work.

Sounds awesome hemmi! Looks just a little complicated LOL Any word on the sense-up? No idea, the technical manual does not state. The camera has no OSD, so you have to send hex code commands via serial. I was focused on setting up the codes for the basic functions. Still learning how to do it. To be honest I know this will not be suitable for DSO work. The sensor is just not up for that task. I'm just hoping its sensitive enough to see bright stars for alignment.

Good point Johnno, I can see the R pi coming into our sport at some stage as they are improvng the cameras but maybe far off yet.

This one is at x64 or 1 sec, 90% dark outside. Zero gain. Glow at bottom is from street light.

Seems I have full control of all settings now from the computer. Everything seems to work well. Max exposure is only 1 sec (x64) so it will not be sensitive enough for DSO work, but I knew that. 1 sec should be plenty for planets. Dynamic range seems good, not as good as my pixim but not bad. Zoom works flawless. I also have control of the IR cut filter via the computer.
It should be plenty sensitive to align on bright stars with camera in. Next test is on the scope when I get a chance. If that works well I can put it all in a fancy case.
