TS-Optics 2-inch GPU Superflat 1.0x Newtonian Coma Corrector – Product description

Four-element 2-inch coma corrector for Newtonian telescopes around f/3.5 to f/6, optimised near f/4.

Key product details

• Astrophotographers using fast Newtonians
• f/4 imaging Newtonians
• Cameras with medium to large sensors
• Four-element optical design
• Suitable approximately from f/3.5 to f/6
• No change in focal length

Product overview

The GPU Superflat is a four-element coma corrector for fast Newtonian telescopes. It is optimised around f/4 and is designed to produce round stars across a large field without changing focal length.

Suitable applications

• Astrophotographers using fast Newtonians
• f/4 imaging Newtonians
• Cameras with medium to large sensors

Included equipment

• Four-element optical design
• Suitable approximately from f/3.5 to f/6
• No change in focal length
• Focus position shifted about 20 mm outward according to product data
• M48 camera connection
• Threaded mounting possible with optional adapters

Working distance

According to the product information, optimum sensor spacing depends on Newtonian focal length: around 53 mm up to about 600 mm focal length and around 55 mm from about 610 mm upward.

Practical note

Measure backfocus very accurately from the specified M48 reference point to the sensor. Even small spacing errors can reduce edge performance.
