I've recently obtained a second hand TQ5 equatorial mount and tripod, motorised in both RA & Dec, but unfortunately without the hand controller. Both motors have individual RJ12 (?) type power connections.

I tried connecting a Celestron dual axis G4 controller (Celestron CG4 mount looks almost identical!), which is working fine on the Celestron mount, and I can hear the digital pulses clicking the TQ5 motors, but no movemement!

Upon opening the units for closer inspection, the TQ5 motors are simply oscillating tiny movements back and forth and not rotating.

Can anyone suggest a hand control unit that may operate a dual axis motorised TQ5 correctly?

Many thanks in advance.

"I tried connecting a Celestron dual axis G4 controller (Celestron CG4 mount looks almost identical!),"

The TQ5 looks like an EQ5/CG5 mount, not the EQ3/CG4. The Skywatcher EQ5 dual axis or the SW EQ5 enhanced handset or the Celestron CG5 handset might work, with no guarantee. Failing that, the SW dual axis motor drive kit should also fit..

      Hello 
       
      I need reviews on Celestron CGX L. Is it a good mount ? My scope is Celestron cpc EdgeHD 1100. 
       
      reliabilty ?
      disconnetions ?
      tracking ? 
       
      My current mount is Celestron Alt Azm Mount and  I have all my accessories from Celestron like focus motor, Starsense, Skyportal, All Star Polar. Allignment etc, these have made my life very easy. Else I do have option to buy ioptron CEM70 but I’m not familiar with the product but most of my Celestron accessories which can be connected to CGXL will go in waste. 
       
      Secondly how important is the GPS that I will have to buy separately because CGXL doesn’t have built in. 

      Thirdly I can buy CGXL without mount. Is there any way I can fit this on to my current Alt Azm Mount? Or Pier. I can easily save 1100 USD. 
       
      Right now my Telescope is fitted on the Alt Azm Mount and giving me lots of disconnections on WiFi. That’s the problems I am facing. If it’s no more in new CGX L I would go for it. 
       
      im confused.

      I've seen a Celestron FI 130 come up locally for pretty cheap. Had a close look at it, and since it has a dovetail mount I can remove the scope and put my DSLR rack on it. The aluminium legs are very slightly wobbly, but I'm pretty sure I can stiffen the tripod with a few extra bracing members. At first glance it looks like a cheap and easy way of getting motorised tracking for my Astrophotography, but my main question is how good is the tracking on the mount? Is it accurate enough for wide field Astrophotography up to about a 400mm lens?

      This is Celestron cg3 mount suitable for any telescope tube with vixen dovetail.
      Load capacity is approximately up to 4 kg
      Condition is used, but in very good shape. 
      It's comcompletely with 3d printed levelling plate, under tray for accessories, slow motion and locking knobs.
      Mount was completely stripped down, removed factory sticky grease and applied proper grease where applicable.
      Price: £90
      I can post it by Hermes or DPD if you are happy to pay for postage.
      I'll accept PayPal as family/friends or commercial if you'll pay the 3% fee.

      Made a new video, this is a Astro Systeme Austria specific video, which has direct driven servo motors.
      To get them to perform perfectly and be able to track unguided, you have to tune theese motors.

      I made a quick video of how the three different methods is working in the "Autoslew" software to run theese mounts.
      Maybe this method of tuning mount motors is related to other brands which has direct driven mounts? 

      Best regards / Daniel
