Dual Vixen M3 plate

For sale is an Astrodevelopments M3 plate (14 inch long version) with two Vixen style dovetail clamps. This allows two scopes to be mounted side by side very rigidly. The M3 plate is a heavy piece of kit. One of the clamps was a prototype and had one of its four mounting holes drilled in slightly the wrong place. This means the silver colored clamp is secured to the M3 bar with just 3 bolts instead of four. Makes no difference to holding the scope securely but thought I should point it out. Looking for 100 including postage or 90 collected.
Payment by bank transfer preferred.

**SOLD thanks Jamie** Various Arduino board and stepper motors
Including Ascom auto-focuser


Here's a selection of Arduino boards and 4 stepper motors that I was playing with for various ideas.
There's an Ardunio Uno mounted in a box that is loaded with some Ascom stepper focuser software, which worked the last time I used it, but have since bought commercial products as I've upgraded my equipment.
Great selection to have a play with and learn some programming.
I don't know what's on these board, if anything. They're easy to wipe and upload with multiple programs from the internet.

I'm looking for a dew heater/controller. I would preferably like more than one channel. Let me know hat you've got and how much you want.

It's to fit a 8" Newtonian, 2 x 50mm finderscopes so may just need to buy some more strips or make up one.

Curious what people have for sale. Not looking to break the bank but would like it to run off of a 12v car/adapter plug.

FOR TRADE: Celestron C8 with Moonlite focuser and guidescope for 90-110mm APO (or anything else of interest)

I am just testing the waters here.

I have a celestron C8 wihich barely gets used. It is the current black model, non fastar.

It has a matching orange Moonlite CS dual speed focuser that is nearly new, a vixen dovetail and a CGE dovetail (vixen has a few marks on it) and a dew heater band. For the right deal I may also be able to throw in a Skywatcher ST80 with losmandy bracket for use as a guidescope.

If anyone has an APO refractor that they might be willing to trade then please let me know what you have. I estimate the value to be in the 700-750 range (800-850 with the ST80 and losmandy bracket).

I am looking for scopes between 90-110mm, obviously bigger would also be considered but I realise that bigger may be out of the question for a trade.

I would also be happy to listen to offers for the equipment as it is a shame to see it sitting there doing nothing.

Happy to meet halfway with anyone.

I am in Leicestershire.

Celestron C11 SGT

Hi All,

I have a brand new Celestron C11 SGT (CG5 goto) it was bought from David Hinds last May 2016 but never used, I believe it was just old stock but the OTA is the current model.

I have not had a chance other than turn the mount on to power test it to actually take this scope outside due to weather and my work pattern as I work shifts.

I prefer the Meade LX series fork SCTs I have owned these in the past and prefer carrying them out in the usual two piece as opposed to shipping out a bit by bit which comes with a EQ mounted scope. It comes complete with Dew Shield and the mount has a Polar scope.

If anyone has a LX90 / LX200 10in to 12in modern version which they would not mind trading then let me know, if there is a requirement of a additional cash payment to be made that's fine.

I have all the paperwork and original boxes for transport.

Thank you for looking

11" Compact Dobsinian F4.3

Iv unfortunately got to sell this lovely telescope as i'm moving house and cant take it with me due to space.


the dob has had very little use by me.

its a 11" 4.3f scope made of wood with a very interesting style. if your eyepeices run out of focus you can extent or subtract the poles holding the secondary to get more, a really good idea. it also has a rack attached for a single 1.25 and a 2" eyepeice, and has a 2" focuser (rack and pin) with a 1.25 adapter it all packs into its box (mounted on a rotating cradle) but the poles obviously are separate but do slide in, and on the base of the box is a computer 12v fan but iv never tested it (dont keep 12v batteries around sadly) iv tried to take as many photos as i can but if theres any you want just let me know.


unfortunately due to the size and type i dont feel confortable posting this but i am willing to deliver within 20 miles of NP4, obviously with a little fuel money or even meet you half way, just let me know and see what we can do.
