If you own an FSQ, an FS-102, 128, or 152 this accessory is a must for visual astronomy. It removes whatever false color there may be in my FS-152 even on the brightest objects. Several amatuers viewing through the Extender-Q and the FS-152 freely admitted the absence of any visibly discernable false color. There is no reduction in image quality - period! Fantastic quality and workmanship. Its even configurable for using with the binoviewer to double your viewing pleasure. Talk to Anacortes for appropriate adapter information.

I bought the extender for my FSQ-106 to go along with a Bino-viewer...As there is no false color in the 106, it did increase the visual clearity and worked very good with the Bino...The various attachments can be a bit tricky but well worth the time and effort...This is a very good accessory, one I highly recommend for visual astronomers!
