Hi all I've had a good look at the inside and wiring. The plan is to remove the back and keep the body on the camera end. The reason for this is to fit a fan inside and replace the rear with a metal grill to allow air flow. The control end will be boxed at the other end. So there will be one cable coming from the scope, supplying both power and signal and OSD control. Hopefully this will work without interferance. The cable I will be using is from an old security camera containing five wires. The four way pin wiring is the electronic iris control and therefore not required for my purpose. So this leaves just five wires to extend between the two parts. I will post as it progresses.

Lol Karl no pro it is the quest for heated observing :)Pity the coaxitron controller dosnt work with it. If it works out the camera will be the same weight nearly as an eyepiece, running cooler and a single cable back to the house. Should have the cables soldered and connected tomorrow and test to make sure theres no distance problems with signal will keep posted here.

Carl For me now the ability to control the camera remotely is essential so I wait with baited breath! I am planning to get another one of those coax controllers for the other CR6 as it's a pain having to swap from camera to camera!

Sounds great Carl! Looking forward to seeing how it works out Have you had a chance to use the camera or play about with the settings? I had to change the colour settings quite a bit to get them right.

Just the basics so far Chris with a SLR lens I will have to write down the colour adjustments etc but I got them looking natural have to get used to them yet.

Hi all had the soldering iron out today after fixing 4 Sky dishes from storm damage . I managed to find a peice of old speaker grill and was easy to cut for the back of the cam. The fan is then connected to the grill on the inside. Cut the cables and soldered them to the long cable then hot glued them for insulation, a futtery job I have to say. Ran a test first before hot gluing to make sure everything worked. Everything seems to work fine. One problem I have found is I cannot connect the fan to the DC wiring inside the cam as it causes interferance So the fan will have to connect to the scope supply, not a huge drama. As the solder and wire joints are delicate to stop the main wire pulling out of the camera body I placed a cable tie tightly around it on the inside so it stops any accidental pulling. The control end I am still working on it will have to attach to a small box of some sort. Attachments:

Top job Carl.
Do you have the fan sucking hot air out or blowing cold air in? Apparently sucking hot air out has been proven in test to work better than blowing cold air in. Strange.

Funny enough thats what found testing my sammy mod last year baffled mea bit.

Interestingly, that's how a refrigerator works too. It draws heat out of the fridge and into the cooling grill (Heatsink) on the back, not pumps in cold air. Surprising how many people think Fridges pump cold air in.

Yes folks the fan is sucking air out. In theory it should be a bit more effective than the sammy fan due to the small camera casing which is also difficult to work in.

Coming along nicely Carl. The rear control panel, can you not cut a bit off the casing so it clears the connector plugs and fit a flat plastic sheet on the back of it or use a bit more of the speaker grill to help it to keep the controller section a bit cooler like you did with the front section of the cam, could make it a bit easier for you instead of trying to make a box for it

Looking at it Johnno you would have to cut the cam shell in half to have enough room for that one. The design is so small it is difficult to press one of the OSD buttons as it is so close to the BNC plug, also the power plug position dosnt help. If I was able to get a suitable box from Maplin, the BNC can easily be removed from the board and attached to the side of the box via a short bit of coax and the power plug the same. That would then leave easy access to the control board on top. The good news is there is no effect on the camera with the 10 meter cable Had a full test today. Chris the colour via the SLR lens I found the settings around natural, Colour Manual RED 59 BLUE 94 If that helps, still playing with the AGC but need stars for that one. Carl

looking back at your first pics where your holding the casing I can now see how small it is compared to your fingers me personally, i would of left the cam intact and make a big hole for the fan on top and a couple of holes near the front so the fan can suck in some cold air and extract it out of the top and just make a remote control box Forget what I've said above, I should read your posts more carefully,

There is a problem with making a control box Johnno. It isnt a case of wiring the buttons unfortunatley. There are only two wires that control the OSD from the back board to the front hence there is so little wiring, they are the black and white ones.
As far as I know the the buttons use surface mounted resistors to send different values down the two cables to the front board. so would be a lot more tricky and some very fine soldering.
If this wee fella had Coaxitron control it would be perfect as you could also power the fan from the rear board which wouldnt cause interferance.
Hope that makes sence?
