Lately I’ve been having trouble with the dual speed focuser on this scope ( focusing out or up ) using my JMI remote focuser as this new ASI2600MC weighs 720gm with spacers compared to the old Canon 600D at 570gm. So after 3 years of use I decided to pull the focuser out and give it a good service.It had almost no grease in the main bearings so cleaned it up with turps , re greased with lithium grease , a fine coat of wax on the flat of the draw tube, re adjusted tension, re installed and now works beautifully, should have done it a year ago
Comments most welcome
