Everbrite Diagonal for SCTs to maximise fork-arm clearance The model DPS-2004 Everbrite diagonal for 2" eyepieces matches the model ACS-0004 SCT adapter which is 0.7" shorter than previous models to maximize SCT fork arm swing-through clearance on such telescopes as the LX90.With the Celestron f/6.3 reducer, the short 2" diagonal system acts at f/5.5. With this setup, a 27mm Panaoptic yields a 1.5º true field on a C-8. |
