Need help on Skywatcher AZ-GTI and EQ Wedge mount setup.

Recommended Posts

After being initially excited at getting my first mount. I found that the instructions that came with it aren't much help. I'm trying to use the mount with my canon camera and 70-200 lens. 

I know I have to align the mount to the celestial pole but do you do this before turning the mount on?

How does the mount know if you are using the camera on the left or right side?

Sorry for what are simple questions but I feel once I get these sorted I can start enjoying my new hobby instead of being frustrated at the first step.

Skywatcher mount encoders work on movement, and not position. The Synscan software sets its position registers to zero at power-up, and then counts pulses from the mount's axis encoders, to work out where the mount is pointing as the mount moves. With an Az/Alt mount, zero equates to horizontal facing North; and, as I understand it, in EQ mode with the wedge facing the NCP, RA & Dec at zero. The best way, is to align the OTA on the NCP (with RA & Dec at zero), using the mount's motors, then cycle the power, and, set the correct time and date.

It probably does not matter, providing that sidereal tracking moves the mount in an easterly direction. At power-up, the software is not "concerned" where the dovetail clamp is facing, as long as the optics are facing North.

      My Az-Gti has ceased to function: red light does not flash when switch is turned on and wifi connection can not be found by iPhone app.
      installed fresh set of new batteries but still it does not switch on. Plugged a 12volt battery eliminator and it seems to work, as light flashes and wifi connects!. Checked leads in battery holder, looks ok. Maybe a loose contact inside?  Taking mount and a Heritage 130to Argentina/Chile for eclipse and dark skies, so battery operation a must.
      Any suggestions appreciated.

      I had bought this in the hope that i will do astro trips more often. Hasn't happened and i use my avx at home. So this is not finding much use. 
      An extremely portable setup, the mount with weight and tripod leg spreader fits in a shoe box. The stock nuts have been replaced by winged nuts for easy grip in the dark.
      One of the tripod's legs suffered a slight damage, but I've taped it well and does not affect its performance. 
      I will include the computer connecting cable as well as polemaster adapter.

      Will prefer pickup from London as the postage may be tricky due to the tripod

      I have used my Star Adventurer for a while now and is very satisfaid with it. But it could be improved and I have installed an angled viewfinder to the polar telescope, rebuilt the wedge, etc.
      But there is also the tripod, the one I have now is stable but very big, nothing that I could take with me when traveling. All photagraphy tripods I have looked at that is maximum 0.5 meter long folded look a bit weak or are very expensive. Now I have bought an used Manfrotto model 144, very stable but too long folded. This weekend I cut off the legs to make it shorter. I don't need very high tripod now when using the angled viewfinder.
      Here is my tripod project:

      I've made a serial connection with my pc and my Virtuoso and i'm trying to send commands to my mount via Matlab without passing trough a Synscan controller but I'm not sure if it is do-able. I found the communication protocol of the Synscan (attached). Can I use it to send the same commands on a serial port directly connected to my mount ?

      This is my very first time working with a telescope and i'm having trouble connecting my mount to my pc (It seems very easy for you guys, shame on me).
      I've followed a lot of threads which helped me a lot on this forum but it still won't work.
      This is what I've done:
      -I've build a cable RJ12/USB with a USB/TTL chip connecting the Rx to the Tx, the Tx to the Rx and the GND to the GND. (with the adpated  driver which works fine)
      -I've installed the Driver "AzGoto by Armazem Do Telescopio"
      -I've installed the ASCOM plateform
      -I've installed StellariumScope, Stellarium and Skychart
      -In both softwares I chose the Driver AZ GOTO, fill in my latitude and longitude and the appropriate port COM
      But when I try to connect my telescope, I have to wait over 5 minutes until an error pops up with 'BasicApi.MountControlException"
      Do you guys have any idea what's going on ?
      Again, these are my first steps into Astronomy.
      Thanks you very much.
