مستعمل - قناع باهتينوف للتركيز لتلسكوب RASA 8"

The grab handles the previous owner added are a lifesaver—no more wrestling with the mask in the dark. It slips on and off my scope in seconds, and the focus stars snap right into place. Totally worth grabbing this used unit.

Pulling the focus mask on and off my 8" RASA used to be a hassle, but the grab handles the previous owner added make it effortless. The alignment spikes are crisp and show a perfect diffraction pattern on the first try. I'm glad I saved money on this used piece—it's working just as well as a new one

The grab handles the previous owner added are a game-changer for swapping masks in the dark. Took a few minutes to align on my RASA, but once dialed in, the diffraction spikes were spot-on and sharp.
