Askar ACL200 lens is specifically designed for astrophotography. It comes with Vixen style dovetail and helical focuser. Focusing can be quite time consuming process even with the Bahtinov mask (especially with narrowband filters). Additionally, focus can shift with temperature change during the night. We have solved this for you with our dovetail kit mount. It works on the same principle as our hit product – WO RedCat autofocuser!
Check out our AF3s autofocuser dovetail kit. But if you are an ASIAIR adopter, we have also prepared a dovetail kit mounting solution for the ZWO EAF autofocuser.
