Explore Scientific Field Flattener for Refractor Telescopes
Field flattener for refractor telescopes (f/5 to f/7) reduces star distortion, requires ~55mm spacing to sensor, and uses T-ring attachment for cameras. Positive user insight: consistent high-contrast astrophotography results
Highlights
- reduces star distortion across field
- designed for f/5 to f/7 systems
- secure camera attachment via T-ring
Pros
- reduces field curvature-induced star distortion
- compatible with f/5 to f/7 refractors
- 55mm +/- 2mm sensor spacing requirement stated
- T-ring thread for easy camera attachment
- fully multi-coated optics for high light transmission
Cons
- spacing tolerance +/- 2mm
- requires camera with compatible T-ring
- works specifically for refractor-type telescopes
Best For
