The all new Wide Photo Refractors bring on new edge to the family of Parabolic Newtonian Reflector. The CFP2008 OTA and CFP2501 OTA are now equipped to bring faster focal ratio at F/4 that allows less exposure time to produce a superior quality image. They are made of carbon fiber tube. Therefore, they are not only lighter, but stronger and also have much better thermal stability comparing to a common aluminum tube. This becomes especially important for astro-photographers dealing with long exposure astrophotography. Telescopes made of less thermally stable material may deviate from its optimal focus after pro-longed exposure. The CFP2008 and CFP2501 also come with an advanced 2” dual speed linear power focuser that will not shift while supporting heavy equipments and provide smooth and precise focusing without vibration. This makes them excellent camera supporter, even with a mid-size mount. The CFP2008 and CFP 2501 are not only best for photography, but also as fine visual scopes.
