Well I would like to post an update to this saga - Gaston has provided for me the adapter to allow the connection of the OPTEC 6.2 reducer which I have shown in the pics below. Thank you Gaston for that part – its like having the key to the Ferrari but no steering wheel
Given the one day of clear skies since it arrived i have not yet got to use it but it will shortly come.
I originally had some concerns over the grub screws not being long enough but being the complete tool that I am I needed to get the right tool

. The allen key wasn’t quite right and wasn’t allowing me to nip it up, 10 dollars at Bunning’s got me a new kit and the right key (a ball key) which fitted the job precisely. Its nipped up and will be installed very soon.
I am looking forward to this – in desperation I turned to planetary imaging while I was waiting…… but that’s another story….
The next update will be the unit fitted and working – hopefully.
