We don’t recommend use of the SkyScout as a finderscope.
There are two reasons:
1. SkyScout is built to be sensitive to magnetic fields in order to determine orientation of the unit. Mounting the device on a telescope with its metal tube, mount castings and drive gears, counterweights and tripod will significantly affect its magnetic accuracy and will probably give you a magnetic icon warning.
This is true even if you use a non-magnetic bracket, like the one supplied with the SkyScout Scope 90.
2. SkyScout is simply not accurate enough to point a telescope, as it was meant to be used with the unaided eye. It should point you to about two to three degrees of the target (within the unmagnified view in the viewfinder). It is not accurate enough to place an object within the (usually) much narrower field of view of a telescope’s eyepiece.
