Imaging with the ED T CF Refractors
The ED T CF refractors make very capable astrographs for your CCD or DSLR camera. To attach a DSLR camera, all you will need is the appropriate
The ED T CF refractors were designed to reach focus with both DSLR and CCD cameras and additional accessories like filter wheels and flip mirrors. Because of this, you will need an extension tube to reach focus if you are only attaching the camera without additional accessories.
Imaging equipment is sometimes heavier than a diagonal and eyepiece. The
Care & Maintenance
Give your telescope reasonable care and it will last a lifetime. When not in use, keep its dust cover on as well as the dust cap on the eyepiece opening. Keep the telescope inside its
packaging when not in use. Store it indoors or in a dry garage. Do not leave the telescope outside except when using it. If a scratch appears on the tube, it will not harm the telescope. Smudges on the tube can be wiped off with standard house- hold cleaners.
Dew
When you are ready to pack up your telescope at the end of the night, avoid immediately storing it if you encountered heavy dew and the telescope is damp. Instead, bring the telescope inside and allow the moisture on the telescope to evaporate. If dew forms on the objective lens, then leave the dust cover off of the telescope until all the moisture has evap- orated. Once the telescope has completely dried out, place it back in storage.
Cleaning Optical Surfaces
In general, your telescope will only need to be cleaned on a very minimal basis. Dust particles on the objective lens do not effect the optical quality of your ED T CF. Loose dust can sim- ply be blown off with air, using a compressed air can or blower bulb (available from Orion). Any remaining dust is best left alone, unless the build up is extreme. Finger prints and water marks should be cleaned from your telescope’s objective lens. Any quality optical lens tissue and cleaning fluid spe- cifically designed for
