lxd500 mount with DH motors
      #5627500 - 01/17/13 06:43 AM

Hello,
I use this mount with a 497 autostar but I have forgotten what are the values for the Az and Alt ratios.

Where can I find them ?

Assuming LXD500 has the 144:1 worm ratio and DH4 - worm shaft spur gear is 1:1, then the value is 6.57066.

P.S. DH4 gear ratio is 410.6667.

Thanks
So I have to enter +6.57066 for the 2 ratios ?

Info is sketchy on LXD500's worm ratio, Some says it's RA 144:1 and DEC 144:1.
Also I wouldn't know your mount's spur gear design so I have to assume it's 1:1.
BTW, if it's going toward the wrong direction, change the sign.

Yes, the DHs are direct mount, i.e. 1:1, to the worm axle.
