Product Description

50ED Guidescope 50mm Photoguide Refractor OTA with Helical Focuser Telescope Accessories

Features:

1. The 50ED 50mm guidescope with upgraded helical focuser makes highly accurate guiding of deep space astrophotos affordable for any astrophotographer. It equips upgraded helical focuser to eliminate any possible play in the focuser over its entire travel range.

2. The guidescope is a 50mm aperture 240mm focal length (f/4) achromatic refractor with a helical focuser. The focuser can rotate as well to help you get the perfect framing. It has dual mounting rings. The rings are attached to a riser block that uses a standard Vixen style mounting foot. Add an optional small-chip CCD autoguider, and you ready for automatic guiding.

3. The guidescope's helical focuser has a lock on the rotation for your CCD autoguider during focusing. The helical focuser simply moves the attached autoguider in or out while maintaining its set orientation. This ensures that the field of potential guide stars will not rotate when focusing.

4. It superb for guiding long-exposure DSLR and CCD astrophotos. It is usable with refractors and imaging Newtonians up to 1500mm in focal length, as well as longer focal length scopes.
