  1. Longer and stronger stepper motors will draw considerably more current and may well overload the drivers on your control board. I would be very cautious about such a change on any Sky Watcher mount... they tend to be unforgiving of such things and just blow the control board... EXPENSIVE to replace.
  2. Hi, According to this OVL adv, it shows back focus distance as 55mm. https://www.bing.com/images/search?view=detailV2&ccid=JezXYvC2&id=50948A70E3E6C55655E7AFC07DE95C10748FFB14&thid=OIP.JezXYvC2F0gmer2S5Xu18wHaGw&mediaurl=https%3a%2f%2fwww.microglobe.co.uk%2fimages%2fOVL-Field-Flattener-Adaptor-20225-2.jpg&exph=1060&expw=1162&q=ovl+field+flattener&simid=607991568116549632&ck=CF5150662E0C6744248937ED8F6DB50B&selectedIndex=0&FORM=IRPRST&idpp=overlayview&ajaxhist=0 I hope this helps.
  3. It is good to hear that you have resolved the problem, albeit at considerable expense to yourself. There has been several cases of faulty assembly with this particular reducer and it would seem that you have another one to add to the score. You have a VERY strong case for returning the original one for a full refund as you can now prove it is faulty, especially if the new one was purchased from the same supplier. Even if purchased from a different supplier you can still prove it is faulty and not fit for purpose and should be able to get a full refund on its return. As you
  4. Looks like Jupiter and possibly Saturn as well. Great shot.
  5. Just ordered a copy, it is a remarkable achievement for one so young. I wish him all the best for his future.
  6. Don't be in to much of a hurry to blame the motherboard... there are several other possibilities. 1, Does the small red indicator on the mount show a steady red when powered up?... if not then it could be a dodgy power lead or a bad connection on the input socket... see 3 below. 2, If the red light is on and steady, try using a straight through Ethernet cable (same as the one connecting your PC/laptop to your router) to connect the handset to the mount... if this allows the handset to power up then the curly cable is the problem... a reasonably common problem for these handsets.
  7. Sound like a possible power issue. How are you powering your mount?... if using a battery, check the voltage output from it under load (mount etc connected and switched on). If it is less than 12v then you need to recharge the battery. If you are using a mains driven DC power supply then check it's output voltage and also the connecting cable from supply to mount... note also: a DC power supply (or battery)should be capable of at least 5 amps continuous output at the DC voltage being used. The handset gets it's power from the mount so any issue with the mount supply will ef
  8. Hi Jonathan, You can get a replacement handset cable from FLO. https://www.firstlightoptics.com/astronomy-cables-leads-accessories/lynx-astro-premium-handset-cables-for-sky-watcher-eq6-or-neq6-syntrek-pro-mounts.html Not overly cheap but better than a blown up Mother Board and I don't think you will find a better one, or cheaper. Hope this helps.
  9. Hi Shimrod and Mike, You will need to have a 2" dia extension of between 55 -65 mm optical length to compensate for the removal of the diagonal. This should achieve focus with the 533 at around the halfway point of the outward focuser travel. The focal point of the ED80 is approx 110mm from the outer face of the focuser draw tube without the diagonal fitted, and with the focuser fully retracted. Hope this helps. Good luck and clear sky's.
  10. Hi FMA, Sorry to read that your mount has to be returned, however, Flo will get you sorted in as short a time as possible... they are one of the best, if not the best, in the business.
  11. Hi guys, The modem/router to PC/laptop path does not use all the wires in the RJ45 connector there are 2 or 3 unused in that function. These spare wires are often used, by various manufacturers, for other things when the cables are used in a different application, like carrying power to/from mount and handset. The only common ones would be TX data, RX data, possibly one or two handshake lines and the common ground (0v) connection. The best way to check is to use the router cable between the mount and the handset.
  12. It looks like you have the mount powered correctly , however, this does not confirm that the curly cable is not damaged. I had mine break one of the wires internally due to the flexing of the lead during use out in the cold... sadly it is a fairly common problem with Synta cables. You could try using a Cat5 straight through patch cable (same as the one connecting your pc/laptop to your router) to eliminate this possibility. If that does not solve the problem then it is possible that there is a fault either in the HEQ5 mount power distribution or in the handset in which case you
  13. I concur with Seelive, however, it could also be that the curly cable is faulty and not picking up power from the mount. Be very careful if you test the mount with a meter whilst it is powered... it would be quite easy to short out the pins possibly damaging the circuit board.
  14. Hi FMA, More information required to find out possible solution. What mount are you trying to set up? (make and model number) How are you powering it? And how are you connecting the handset to the mount?... i.e. What cable are you using to connect the handset? If the mount is powered properly it should send power to the handset... no other connections are required.
  15. Don't give up yet, there are several places to purchase gears from. First thing is to measure the following: - as accurately as possible (preferably using a vernier caliper or Micrometer). Take these measurements in both Imperial and Metric. 1. The outside diameter across the tips of 2 diametrical opposed teeth (use relatively undamaged teeth). 2, The OD of the hub section. 3. The bore through the hub. 4. The thickness of the gear section. 5. The thickness of the hub section. or the total thickness of gear and hub. From this you can determine if the gea
