4. Attach the camera body to the T-ring as you would attach
it to any lens.
5. Tighten the T-ring to hold the camera in place.
6. Be sure to set the camera to the desired orientation by
loosening the lock-ring and rotating the entire accessory
adapter and T-ring to the desired position.
7. Tighten the lock-ring and then inspect the entire assem-
bly to make sure all attachments are secure.
8. If desired, attach the scope to an optional tripod by
threading the the 1/4"-20 stud on the tripod into the
threaded hole on the bottom of the scope.
cleaning and care
The closed optical tube design of the Orion MAK-500 helps
keep it free of dust and grit. Avoid removing the eyepiece and
diagonal, or accessory adapter and camera, from the MAK-
500 in environments with lots of airborne dust and/or grit.
Lens and mount caps should always be in place when the
scope is not being used. Storing the MAK-500 in its carrying
case can further protect it against dust intrusion. It is impor-
tant to remember that the lens surface of the Orion MAK-500
is coated with high-performance anti-reflection coatings that
can be damaged by careless handling. (Telescope, eyepiece,
and camera lenses are generally cared for in the same man-
ner.) Please follow these simple suggestions:
•
The optics should be cleaned approximately twice a year
or as necessary when they are dirty. The dust that builds
up on coatings promotes mold growth. Mold can etch
glass and destroy coatings.
•
Never touch lens or mirror surfaces with fingers or any
coarse material.
•
Avoid over-cleaning; it can damage coatings.
•
Always use lens cleaning tissue and fluid that is specifi-
cally designed for multi-coated lenses (such as Orion
Optics Cleaning Kit #5825). Do NOT use fluids or tissue
made for eyeglass or household use.
cleaning the Front lens
1. Make sure your hands are clean.
2. Blow any particles or dust off the lens with a blower bulb.
3. Have several pieces of lens cleaning tissue at hand,
ready to use.
4. Put two drops of lens cleaning fluid on a piece of lens
cleaning tissue (NEVER directly onto the lens!).
5. Clean a small area at a time, using a new tissue for each
small section.
6. If the lens is extremely dirty, wipe across it only once for
each tissue, alternating wet and dry. (The more fresh
tissue you use, the less likely you are to scratch your lens.)
7. Always avoid excessive pressure or rubbing, which can
destroy the coatings.
storage and cold Weather
All optics have the potential to fog. Fogging occurs when an
optical instrument is exposed to excessive temperature
changes or high humidity. Always allow the optics to slowly
adjust to cold weather by storing the instrument in its case for
a few hours in a cold area such as an unheated garage or the
trunk of a car. When bringing the instrument back inside a
warm building, store it in its case in a cool area for an hour or
two. It is very important to then open the case, remove the
lens cap, and let everything dry overnight. The MAK-500
should always be stored in a cool, dry place. Storing it in a
moist environment will result in mold growth and destroy the
optics. This is NOT covered by the warranty.
