Explore Scientific HR 2 coma corrector (47657)

The Explore Scientific Coma corrector stands out as a unique optical accessory, offering exceptional performance for both visual and photographic use. This versatile device extends the focal length by only 6%, making it highly efficient for various astronomical applications.

Key Features:

• Complete Package: Includes a helical fine focuser, T2 adapter, and M48 adapter

• Exceptional Performance: Visual polystrehl value of 0.98 at f/4 and 0.96 at f/3

• Versatile Use: Can remain permanently in the telescope, enhancing clarity for both planetary and deep-sky observations

• Image Diameter: 30mm, optimized for 2" and fast optics

• Corrector Tube Length: Approximately 85mm

Visual Use Requirements:
For visual observations, the focuser should have an adjustment range of 32mm available when the focus is at the same level as the drawtube. This requirement is less critical for photographic use, as the HR Coma corrector extends the focus by about 35mm.

Compatibility:
If a camera can achieve focus without the corrector, it should have no issues focusing with the corrector in place.

Specifications:

• Connection to telescope: 2"

• Optical length: 85mm

• Type: Flatteners, Correctors, Reducers

• Type of build: Coma corrector

This Explore Scientific Coma corrector is an essential tool for astronomers seeking to improve image quality, particularly with fast optical systems. Its ability to correct coma aberration while maintaining excellent optical performance makes it a valuable addition to any astronomical setup.
