After trying to decide between Moonlite or a Williams Optics focuser for the 6" frac this is what I did...got a GSO Linear Bearing focuser instead! Reviews on CN weren't that good on the old 10:1 focuser but this new one got the thumbs up.
Good points: Great value $250 landed at my door from Agena Astro in the US. Straight swap for the old R&P focuser, easy. Focuser rotates, something I thought was not necessary but used first time out made viewing easier. 10:1 reduction is really nice. The only negative, the draw tube is short and needs a 50mm extension tube for most eyepieces, so did the WO focuser. Nice addition to the big frac.
