Product overview

The Explorer 250PDS provides substantial aperture for visual deep-sky observing together with a fast focal ratio for imaging. The PDS configuration is designed to make camera focus easier to reach.

Suitable applications

• Experienced visual deep-sky observers
• Astrophotographers with a substantial mount
• Users wanting 10-inch aperture on an equatorial setup

Included equipment

• Approx. 254 mm aperture and 1200 mm focal length
• Approx. f/4.7 focal ratio
• Parabolic primary mirror
• 2-inch dual-speed Crayford with 1:10 fine focus
• Imaging-oriented PDS tube
• Optical tube weight around 14 kg according to product text

Mount requirements

A Newtonian of this size needs a very strong mount, particularly for imaging. With larger camera sensors, a coma corrector is recommended for sharp stars toward the edge.

Practical note

At 10 inches, wind area matters as much as tube weight. Leave substantial mount capacity in reserve for astrophotography.
