QHY Mini Guide Scope

The QHY Mini Guide Scope is a compact and lightweight telescope designed specifically for guiding purposes. Here are the key specifications and features:

• Diameter: The miniGuideScope has a 30mm diameter.
• Focal Length: It offers a focal length of 130mm.
• Fratio: The aperture is at f/4.3.
• Object Lens Type: The miniGuideScope uses a doublet lens design.
• Focus System: Instead of a complex focal adjustment system, you can simply rotate the front of the OTA (optical tube assembly) for fine focal adjustment.
• Focus Locker: Once you achieve focus, you can lock the tube into position, eliminating the need to refocus unless the system is moved.
• Camera Interface: It has a C/CS mount interface, making it compatible with QHY5II and QHY5III series guide cameras.
• Anti-Scatter Light: The internal surface is coated with a matte paint to reduce scatter light.
• Weight (OTA only): The miniGuideScope weighs 111 grams.
• Telescope Connector: It comes with an optional standard viewfinder scope connector with a tripod screw thread.
• Focus Adjustable Range: The focus can be adjusted from infinity to 1.5 meters.

The miniGuideScope is ideal when guide camera pixels are small, and quantum efficiency (QE) is high. Its smaller pixel size allows for effective guiding in a shorter focal length. Additionally, the reduced focal length results in a larger field of view, making it easier to locate bright guide stars.
