Overview
- Unique catadioptric optical system incorporating a meniscus corrector just before a secondary mirror
- 203mm diameter, 2500mm focal length f/12.3
- German Equatorial mount EQ-5 mount with offers stability and tracking precision
- Spherical aberration and field curvature are corrected to a high degree of optical performance
- No need for a front corrector plate which eliminate any dewing problems
- Rack and Pinion focusing placed behind the fixed primary mirror resulting in no image shift
It incorporates a primary mirror and a meniscus corrector just before a secondary mirror. By doing so, light is corrected twice on the optical path. The end result is that spherical aberration and field curvature are corrected to a high degree of optical performance. The system is much more compact and portable than its competition. With the optical correctioin placed before the secondary mirror, it avoids the necessity of having a corrector plate and all the dewing problems associated with a closed optical tube. An additional key feature is the crayford focusing that is placed behind the primary mirror. |
