It has the following modifications:
- three 2.75-lb weights to balance a C9.25 (actually still a bit top-heavy, but the clutches hold..)
- homemade 6-inch plywood half-pier
- wooden tripod from a Vixen Polaris (I recycled the HAL-100 on the Polaris)
- Meade DS motors
- Meade Autostar 497 patched to unofficial firmware 43GF for equatorial mount support on non-LXD55/75 mounts
All told, the modifications added up to around another USD 150 (more than half of that amount was the Autostar 497, not shown) plus I used my trusty Makita router to make the half-pier.
Still haven't tested how accurate Go-To's are, but it seems to track well in RA (but all this trouble for RA tracking!) I also will be able to auto-guide because I constructed a Meade 505-compatible cable to do the firmware update.
