AP 사이트에 보니 오늘날짜로 업데이트 된 제품이 잇더군요..아래사양입니다..막스토프 카세그레인,슈밋카세그레인,RC, 굴절 등 F7~F18사이의 촛점비를 가진 망원경들용 리듀서 이라는군요..
특히 SBIG 의 칼라필터휠이 장착된 CCD에 직접 연결이 되고(X0.67) 휠터 미 장착시(X0.75) 등 촛점거리를 줄여줘서 노출시간을 상당부분 줄일수 잇답니다..$가격은 148달러..
근데 제가 제품정보를 제대로 전달한건지 잘 몰갔네여..ㅎㅎ
July 17, 2003. Our new compact 0.67x CCD Telecompressor (CCDT67) was designed for telescopes with a focal length of f7 to f18 including Maksutov-Cassegrains, Schmidt-Cassegrains, Ritchey-Cretiens, and refractors. It threads onto the nosepiece of your SBIG CCD imaging camera and will effectively compress your instrument by 0.67x when a color filter wheel is used. For instance, your f10 instrument will operate at f6.7, thus significantly reducing your exposure time. The compression is approximately 0.75x without a Color Filter Wheel. Order yours now for $148.
