Oky after many day of hunting around and find info that really wasn't explaining how to get Bluetooth working on Celesteron and all so out of date information, i have managed to get my celesteron 102Gt fully working via Bluetooth.
The adapter used in this test was £23.00 from ebay and we had to downgrade it firmware and all so adjust the way it communicates with our phone / Bluetooth based PC. The System fully works with ascom drivers how ever will not work "out of the box" on the nexstar remote software how ever we will work out a way of getting it to work !!! it just a matter of getting the right Bluetooth adapters and setting them up correctly.
More info will be posted as we confirm our findings.
OBT only been in this hobby for less than 1 month and hello .
7) Some electrical insulating tape and if you wish soldering iron to solder wires together.
8) Flat blade screw driver or Crimping tools (either will do).
Total cost if all parts are bought = £47.33 However if you have parts lying around and use your noggin you can rip some of these parts from old equipment and do it a lot cheaper.
Instructions to follow how to put it all together and how to get it all to work. The may seem expensive how ever compared to being charged a whopping £120 to £180 for the same set up you soon release how easy it is to make your own.

Making the cable from the hand set to the DB9/RJ 45 Plug.
First off we need to make the cable that connects to the hand controller on the Nexstar + (NXS) controller. The firmware loaded on the handset is the latest version direct from Celesteron. This cable goes from the bottom of the Controller (rj9 connection) to the DB9 male plug (via a RJ11 connector in to a RJ45 Plug on the DB9 plug) which will connect to the Bluetooth adapter. Don’t get confused yet it is a lot easier than it sounds …
1) Take your Rj9 (Rj10) telephone spiral cable and cut off one end as close to the end as you can.
2) Look at the second end that has the RJ9 (rj10) connector on it and wright down how the wires are placed. Below is a close up picture of my wire in the Rj9 (rj10) plug. As you can see from the pic below from left to right with plug facing down the colours go Black, Red, Green, and Yellow. There is a extremely high chance your will be different so please make a note of this on some paper as this is very important.
3) Go to the other end of the wire were you have just cut and very carefully remove about 2 to 3cm of the surrounding plastic cover to revel the 4 wires. Now if you push them flat on a table they should be perfectly straight if not get some Scissors and snip them so they are straight as Pictured below If you do not do this the chances are very high that you will not get a good connection later on when you “crimp” then ends. http://img255.imageshack.us/img255/4828/013clo.jpg
4) Now push the end into the RJ9 (RJ10) Plug making sure they go in the correct order as you have written down before e.g mine are Black, Red, Green, Yellow left to right with the plug facing down. The wires once inside the plug should easily be all touching the back of the plastic plug and the black sleeve should be about 1 to 2Cm inside the plug allowing for a snug tight fit.

5) Now for the hard part!!! Turn over the plug so all the pins are facing you and one at a time Force the screw driver flat head down on each pin so that it pieces the wire below it. This isn’t that hard to do just be careful you do not slip and stab you self (words from a wise old man who has done it many times). Pictured below http://img818.imageshack.us/img818/5900/018pe.jpg
