Altitude Knob:
From Steven Bellavia: An improved altitude adjustment knob for SkyWatcher and Atlas Telescope Mounts
This fixed knob is a replacement for the altitude adjustment handle on SkyWatcher EQ6-R Pro and Atlas II mounts. It provides a more positive engagement, making altitude adjustment easier. It replaces in seconds, and will not strip like the stock handle does.
