The steadiness of the air (the “seeing”) will limit how much magni-
fication an image can tolerate.
Always start viewing with your lowest-power (longest focal length)
eyepiece in the telescope. After you have located and centered the
sun, you can try switching to a higher-power eyepiece to ferret out
more detail, if atmospheric conditions permit. If the image you see
is not crisp and steady, reduce the magnification by switching to a
longer-focal-length eyepiece. As a general rule, a smaller but well-
resolved image will show more detail and provide a more enjoy-
able view than a fuzzy, over-magnified image.
Photography with the 70mm Solar Refractor
With an optional camera adapter and t-ring, the 70mm becomes
a 500mm f/7.1 telephoto lens for a single-lens reflex camera.
Steady-Pix adapters are also available for smartphones and point-
and-shoot cameras. For DSLRs, a t-ring for the specific brand of
camera is needed, along with a universal 1.25" camera adapter.
Contact Orion for more details regarding these accessories.
Use the camera’s viewfinder to frame the picture. Use the tele-
scope’s focuser to focus the image. Tighten the focuser tension
thumbscrew to make sure the camera does not slip out of focus.
You may want to consider using a remote shutter release instead
of the shutter release on the camera. Touching the camera can
vibrate the system and blur the resulting photographic image. Also,
be sure to use a solid tripod.
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. Store it indoors or in a dry garage. Do not
leave the telescope outside except when using it. The optical tube
is aluminum and has a smooth painted surface that should resist
scratches and smudges. If a scratch does appear on the tube, it
will not harm the telescope. Smudges on the tube can be wiped off
with standard mild strength household cleaners.
Any quality optical lens tissue and cleaning fluid specifically
designed for multi-coated optics can be used to clean the tele-
scope’s objective lens as well as the lenses of the eyepieces and
finder scope. Never use regular glass cleaner or cleaning fluid
designed for eyeglasses. Before cleaning with fluid and tissue,
however, blow any loose particles off the lens with a blower bulb
or compressed air, or lightly brush the lens with a soft camel hair
brush. Apply some cleaning fluid to a tissue, never directly on the
optics. Wipe the lens gently in a circular motion, then remove any
excess fluid with a fresh lens tissue. Oily fingerprints and smudges
may be removed using this method. Use caution; rubbing too hard
may scratch the lens! Clean only a small area at a time, using a
fresh lens tissue on each area. Never reuse tissues.
