Focusing can be quite time consuming process even with a Bahtinov mask (especially with narrowband filters). Additionally, focus can shift with temperature change during the night. DSD have solved this with their special rods mounted auto focuser kit, which can compensate for the front movement of the lens during focusing.
The autofocusing motor rests on a special trolley, connected to the rails. This keeps the auto focuser pulley in line with the lens focusing ring and enables a balanced, compact solution.
Telescope & EAF Not Included
This was pretty tricky to assemble and setup. There were no instructions so I guess it should be fairly obvious but it wasn't for me.Eventually I got it fixed and practiced focussing indoors looking out of a window and all was ok.On the Askar lens it has huge backlash which made autofocus hard to dial in but in the end it gave good results so was worth the effort.
