The Platform is a Johnsonian Type III+ all stainless steel. It includes the manual, hand control, and AC adapter. It's about two years old and tracks great. It has dual axis control. I used it on a Starmaster 14.5". I didn't do any astrophotog with it so I made an aluminum ground board replacement so that it only adds about 4" to the overall height, the way I made it the dual axis did not have as much adjustment as with out it. The ground board replacment is easily removed with two bolts and full functionality is returned to the dual axis tracking. I'm selling because I want to install goto/tracking on the Starmaster and need to "reallocate assets". It originally sold for over $900 with the dual axis tracking, $500 includes shipping. Can do paypal (help with fee please), prefer money order.
