  1. Thanks. The local pound shop had a pack of 10 and I get light with two cells, so thanks for all your replies.
  2. Dave, thanks. I'll get some LR41's ordered as the AG10/12s that some people have in theirs are not going to fit in my eyepiece.
  3. Hello, Having picked up an unbranded illuminated reticle eyepiece it's come without batteries and the eBay seller isn't communicating (this was bought from a real person in the UK, not from China, so I'd hoped for better). I can get my vernier caliper in to see that the cells need to be 7.9mm in diameter, so that narrows things down, but I can't get the depth of the battery compartment. By eye I reckon I need at least 3 cells. Does anyone use similar 7.9mm sized cells and, if so, can you tell me what they are and how many? Many Thanks, Gavin
  4. Have you aligned the mount first? Having just got my mount and Stellarium talking to each other nicely over a wifi link (V19.3, so direct ASCOM support from Stellarium) I align the mount using the synscan pro app on my PC and then open Stellarium and the scope is then shown pointing correctly to the last alignment star.
  5. A quick update to this thread is that following a bit of to and fro with Skywatcher support (thanks very much for your help), they suggested two options - firstly to try with no other Wi-Fi nearby and secondly to do the motor controller update via the Synscan USB adapter or a handset. I decided I'd invest in the USB adapter as it would give me the option of being able to connect my laptop to the house Wi-Fi and mount simultaneously, so an additional bit of flexibility to what I'd got already. I got a very good price and quick delivery from Bristol Cameras (9/1/20 - Synscan USB adapter currently £19.50inc postage). The MC update went on without a problem and I am back up and running again.
  6. Do you know any links to earlier versions of the MC firmware? There looks to be only 2.09 available on the SW website. I don't have any option to change baud rate via the firmware updater, and my understanding is that the SW wifi adapter is converting to rs232, so you'd hope that was sending data at the appropriate rate. I'll have a look to see if I can change anything in the laptop adapter settings. I have tried with the home wifi turned off, so know that the mount signal is at least 30db above anything else broadcasting using a wifi scanning app.
  7. Hello, Having convinced my wife to get me a SW Az goto mount with a wifi dongle for Christmas off a well know auction site all was going so well with set up, config of Stellerium and Ascom until I tried to update the motor controller firmware... I am now getting the exact same error as detailed here, although on the slightly older version of the mount. It looks like the solution below was to use a Skywatcher Synscan wifi adapter, which I already have, so I don't think this solution is going to work? So, my laptop (Win7) can connect the mount via Wifi and using the SW wifi Motor controller updated it looked to clear the ROM and then started counted up in % until I got the "Firmware update failed. Cycle power to motor controller and try again!" Trying again I get to 1% before getting the same message. Will leaving it unconnected for 4hrs drop it out of the firmware cycle? As I don't have a hand controller can I try the update again via a USB/RS232 combination straight into the laptop without a HC present? I have read about wifi channel inference on other forums, but I don't think that's it, so any suggestions would, at this point be really gratefully received. The only saving grace is that the weather isn't conducive for looking upwards, so I have a few days to try and sort this before my wife expects me to be outside and using the mount. Thanks, Gavin
  8. Thanks for all your replies. After quite a bit of digging, and has been pointed out, this is an old scope, I did find the following information here https://www.nexstarsite.com/Reviews/BaaderBrackets.htm that says Baader made an adapter for this mount to take a dovetail. An email to Baader solicited the following reply: "After the GT mount was discontinued some years ago, we stopped production and sold out these items. Because the newer mounts (NexStar SLT) all have such a bracked already built in, there was no need anymore to produce these brackets Very sorry! Perhaps you find something used somewhere" I've posted this here so that if anyone else find themselves in a similar situation both bits of information are in one place. The 80GT scope and mount was actually on a charity shop eBay listing and sold for £10 which, for that price, was probably a bargain if it worked but I didn't bid for it in the end. Thanks again for all your earlier replies. Gavin
  9. Hello, Does anyone have any experience or knowledge about whether it's possible to mount alternative OTAs with a dovetail or rings to the mount that comes with a Celestron Nexstar 80GT? In particular I am wondering about attaching a SW Heritage 130P? I know that Celestron did a 130mm reflecting 'scope on his mount, but it looks to also have that plastic tube clamp, seen on the 80mm image below. Thanks, Gavin
  10. This was also discussed on the BBC's More or Less at the end of January 2019. https://www.bbc.co.uk/sounds/play/p06yhfbq
