Very nice item and hard to find in the US. This is a Takahashi solar projection set consisting of a white projection screen, a black shading screen, extension rod, specail adapter bracket and a Tak 4" accessory ring. This will fit any Tak 4" refractor, FC or FS series and with a different accessory ring will work well on both the 3" and 5: models as well. I will include a Japanese 20mm H projection eyepiece to complete your set.
This is built with the usual Takahashi attention to detail and finish. Like new, discounts for $235 sell for $150 + postage.
