Also, if you are trying to locate one of the brighter DSOs, this will no longer be able to remain hidden, giving itself up to your searching eye. The Astromania 9x50 finder scope has built-in crosshairs to let you find the correct object more easily and to put it in the middle of the main telescope's field of view. The threads have been kept quite fine but are still very visible against the night sky nevertheless. Two adjustment screws and a compression spring allow very rapid alignment with the main telescope. Precise focusing can be achieved by rotating the objective lens. The finder scope will fit into a large range of holders: Skywatcher, Celestron, Vixen, Orion, GSO and many other makes have compatible finder scope shoes.
