Designed to be used in conjunction with their iGuider 1 guide camera, the iOptron 30mm f/4 iGuider Mini Guide Scope takes the place of your conventional finder using the same mounting dovetail, so you have autoguiding capability without the large guide scope you'd normally need to use. If you have an iOptron CEM26 or GEM28 mount, the scope will mount without the need for any adapters. It features achromatic lenses and anti-reflection coatings to ensure the camera picks up tack-sharp views for accurate tracking.
