2 pairings| Pairing | Magnification | True field |
|---|---|---|
| Celestron Omni 6mm Plossl in the Celestron NexStar Evolution 6 | 250x | 0.2 deg |
| Tele Vue 20mm Plossl in the Celestron NexStar Evolution 6 | 75x | 0.67 deg |
The Evolution 6 pairs the 150 mm f/10 C6 optics with a rechargeable WiFi fork mount. Its 1500 mm focal length gives sharp planetary views and reaches brighter deep-sky objects at lower power.
Because magnification is the telescope's 1500 mm focal length divided by the eyepiece focal length, a 25 mm eyepiece gives 60x here and a 10 mm eyepiece gives 150x. The highest useful magnification is the published 354x, beyond which the image dims and softens without showing more detail.
The focuser takes 2 in eyepieces, so long 2 in wide-field eyepieces such as the Omni 56 mm fit as well as 1.25 in ones.
