The Skywatcher achromatic 9x50 finderscope has a large 50mm objective, wide 45° field of view and a cross-hair reticule for easy navigation.
The 50mm aperture is genuine, it is not stopped down like some cheaper finderscopes.
2.78x more light gathering ability than the smaller 6x30 model!
Easy to setup and easy to use. The mounting bracket fits into standard finder shoes from Vixen, Skywatcher, Celestron, GSO, etc. Additional finder shoes are available separately.
To attach this to a Celestron SCT you will need a Baader Quick Release Finder Base.
To focus the finderscope simply unscrew the lock-ring, rotate the objective, then re-close the lock-ring.Features:

I purchased this finder to use as a guide scope for use with a ASI120MM-S camera. Like others have mentioned the camera cannot be brought to focus for far away objects without the removal of the tightening ring. Once taken off you have 12 mm of additional back space which allows focus. SkyWatcher don't state the focal length of the item but my measurements were 181 mm if that helps anyone else in the future.
Good Basic Finder Scope for the price

Big enough to give decent viewing. Good for use with basic astronomy camera. This requires adaptor. Weighty piece of kit though.
