Description
- Vignetting, edge field aberrations and pupil movement - all introduced when using Barlows with long focal length eyepieces, are minimized.
- Telecentric operation . This is ideal for Hydrogen-alpha filter use such as with Daystar models.
- High performance for image amplification, CCD or film .
- Flexible for visual and imaging with all types of telescopes and eyepieces. Essentially Parfocal, and with nearly constant magnification regardless of image distance behind top surface .
- Higher magnifications are possible with high optical performance compared to "doubling up" Barlows. For smaller instruments, using heavy 2" eyepieces with the 4X POWERMATE may cause balance issues.
