Hi all with the cold coming in and a recent successful observing session from the indoors, I have ordered a number of items. First the power is outside at the scope (12v 3 Amp) so what I need from the inside is, 1. Handset control = 10m Cat 5 lead
2. Camera coax lead = 10m
3. Camera 2 coax lead = 10m
That is basically what I need coming in cablewise (3)
I have ordered 10 x Bullet connectors which will be used for scope/camera power (easy to connect/disconnect).
Ordered some BNC crimp connectors and RCA to make up the camera leads.
The idea of the setup is that it can be relocated to a darker site.
A focuser will be an addition late December
There will still need to be the initial setup of the scope and focus but once done its indoors however it is a basic first indoor setup anyone can do. Pics to follow.

Sounds good Carl and just in time for those cold nights ahead. Have you though about a focuser mod? I've seen guys who make things up with an old remote toy and an rubber band. A man of your talent could whip one up in no time I ordered a 2 channel remote/receiver today that I'm hoping I can rig up with the laser.

I was looking at the one made from two servo motors and it requires no power at all! when you connect the two between a cable and manually turn one the other responds but I dont know what distance they work over.I have an old RC helecopter loaded with them in the attic.
The servo idea may work with your laser switch?
Im still trying to connect the CR6 to the finder but brain freeze but close so many ideas to sort:)

Ooh that sounds good Carl I'd like to see that how that works. I have ordered this www.ebay.co.uk/itm/121117725649?var=420143357963&ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 which I think should do it. I power the receiver with a 12v power source at the scope and then attach the pressure switch cable to one of the channels. If it works I can the use the second channel for something else later on. I also now have the red laser version of the one I showed before. It is not as bright but the CR6 does pick it up. It also worked well after 40 minutes in the freezer

Very good Johnno. I take it the other version is the hand TX stripped down? I plan to strip down an old Kalt Cyclone chopper to gain parts tomorrow.

Carl,The top one's is the wireless version, the middle photo is a project box with the receiver and cristal and servo and battery pack. LED on/off switch with charger socket built in
I was going to chop the TX in half, ie cut off the hand grip just to make it smaller and move the batteries from the base to the back of the TX.
the wired version has batteries, and a variable potential meter for the slow/fast speed and a on/off/on self centering toggle switch.
On the scope I fitted a foam rc plane wheel over the focuser knob and painted a wide white line on it so that I could see if the wheel was turning or not in the dark, I cut a groove around the middle of the wheel so the O ring cord would sit in the groove . I bought a length of O-ring cord cut it to the size I wanted and super glued the ends together,
and did the mod on both servo's for 360 degrees rotation and made up a 5 meter extension lead if needed.
I've looked at the battery free servo mod, but didn't fancy it.
The RC version has had it problems, the servo would start to creep very slowly on its own, even with it trimmed, but found it was down to me not setting up the servo correctly when I stripped it down, there is a small potential meter inside the servo and you have to zero this in. ie find its neutral position.

Chris its RG68 or known as Shotgun cable its used by Sky for Sky +. It is a twin coax (75 Ohm) with foil shelding. I use it in my work so have a lot of it. The pic is a comparison with RG59. Handy for two cams

Good stuff can't see why that wont work at all and a spare channel will be handy! Hi Carl, The receiver and remote turned up today and they work perfect through walls and all!! On another note, I tried the red laser last night and whilst it works now in the cold no problem it is simply not as clear as the green one fore sure. I am wondering if I remove the IR filter in the CR6 if this will improve how the camera picks up the red? Any ideas? Cheers Karl

Although I havnt carried out any tests for lasers I would have to say yes it will help. The general consensus is that you get up to 30% more light pickup with no filter and it should be a lot more sensitive to the red band. Time for the screwdriver Karl!
Also a few white balance settings will need changed I would think.

Also for the optimal settings as I have not got a clue and simply press buttons. Do these cameras have a factory reset button cus I sure as hell could do with one of those

Do these cameras have a factory reset button cus I sure as hell could do with one of those Johnno has a guide on SGL for it, or you can just disconnect the connector from the camera board and apply a 9 Volt battery to it using a couple of pins and you will here it click to the side then just dont reconnect to the board and it will stay in that position out of the way.

Thanks Johhno, I bought one of these but nowhere near warm enough I'm afraid. I had to wrap it in hot hand warmers on it but they don't stay hot for long if you're not holding them. I may build some kind of warm box in the future but the red one will do for now. Thanks again Karl

Thanks Carl, I'll go back and take a look, seems straight forward enough Thanks Karl
