To connecting to ASIAIR PRO, you need to use the two M4x8mm screws in the package. The connecting method can be rather flexible, you can either attach the finder shoe to the back or the sides of ASIAIR PRO.
After you are done connecting the finder shoe to ASIAIR PRO, you can directly attach your finder scope to it, and adjust the tightness via the long screws on the side.
Then use the Dovetail Groove to fix ASIAIR PRO to your telescope.
Use the two M4x8mm screws in the package to connect the finder shoe to the holder ring for ASI cameras.
