Buying Guide
Key considerations
- Optical design: ED glass vs APO triplet; triplets generally reduce chromatic aberration more effectively, benefiting color accuracy in long exposures.
- Focal length and speed: Shorter focal lengths (f/6–f/7) offer wider fields and easier guiding; longer focal lengths demand precise tracking for deep-sky projects.
- Mount compatibility: Ensure a compatible and stable mount; consider dovetail compatibility and whether tracking, guiding, or remote imaging is planned.
- Field flatteners: If planning wide-field imaging, check for built-in field flatteners or optional flatteners to achieve edge-to-edge sharpness.
- Portability vs. performance: Portable 80mm refractors are ideal for fieldwork or travel; larger, more complex designs may offer better imaging at the cost of weight.
- Focusing precision: Dual-speed focusers (1:10 ratio) help achieve finer control for sharp stars; essential for high-quality wide-field astrophotography.
- Coatings and glass: Coatings affect contrast and glare; premium ED glass coatings improve light transmission and color accuracy.
- Accessories: Consider dew shields, flattener/field correctors, and compatible mounts or adapters for your camera and guiding system.
