Astro Engineering BC&F 8" Focus Master & front Cap Meade LX90 Lx200 SCT
In good, used condition.
Info from the web:
Expert focussing and off-axis viewing system - Great astro-photography depends heavily on perfect focus. The Focus-Master is essentially a lens cap with three holes that simply fits over the end of the telescope and helps you achieve perfect focus in seconds. At first glance the Focus-Master is just a focussing aid based on the tried and tested principle of the three-hole mask. Now we have refined this idea and created a mask that not only offers the standard three-hole focussing feature, but by removing the special threaded cap you have a perfect off-axis aperture which has been matched to the useful viewing area between the secondary and the maximum diameter of the corrector lens of popular sizes of SCT. The result is a powerful and versatile accessory that has uses in focussing (photo and visual), lunar and planetary viewing, double star observation and collimation adjustment.
Please note:
Only accessories listed in the photograph's are included with the purchase unless otherwise stated.
