Dr. Flat Master x0.8 GSO RC 望遠鏡減速機/平坦器

The William Optics Dr. Flat Master is an apochromatic triplet reducer/flattener designed for 12" - 16" WO and GSO Ritchey-Chrétien telescopes. It reduces the focal length by 0.8x and flattens the field, making it ideal for full-frame sensors with a 52mm image circle. Featuring an M48 x 0.75 camera connection and a backfocus distance of 86.15mm, this accessory enhances your astrophotography setup by expanding your field of view and ensuring edge-to-edge sharpnes.
