Warning Note: Never look directly at the Sun with the naked eye or with your spotting scope. Permanent eye damage may result.
Before Observing
Attach your spotting scope to a photo/video tripod before trying to observe as the size and power of the spotting scope requires a solid tripod to be
able to see sharp and steady views. For the Ultima 100 models a Tripod Balancing Platform should be installed for optimum balancing on a tripod
(see information below). Make sure to remove the lens cap prior to observing. You can use the sight tube to locate the object you want to look at and
then look through the eyepiece.
Using the Rubber Eyecup
The zoom eyepiece includes a soft rubber eyecup for eyeglass wearers. Fold down the rubber eyecups
to observe the full field of view when wearing eyeglasses. If you do not use eyeglasses, leave the
rubber eyecup in the up position.
Focusing
To focus slowly rotate the focus knob until the image in the eyepiece is clear and sharp.
Refocusing is usually required if the power is changed. If you feel the focus knob no
longer moves any further (in either direction), then you have reached the end of the travel
range -- don't try to force it to go further but you should refocus by turning in the opposite
direction. Once an image is in focus, turn the knob clockwise to focus on a closer object and
counterclockwise for a more distant object.
Changing the Magnification (Power)
Rotate the magnification ring around the zoom eyepiece to change the power level of the
spotting scope. Refocus as needed. The brightest and widest field of view will always be at the
lowest power.
Photography
With 35 mm SLR Cameras:
To use your spotting scope as a telephoto lens, remove the rubber eyecup from the top of the eyepiece. You will shoot through the spotting scope
with the eyepiece attached. Thread an optional T-Ring for your make and model of 35 mm camera onto the T-threads located at the top of the
eyepiece. For Ultima 65 models, thread the T-ring adapter (included with your model) onto the eyepiece threads, then you thread a T-Ring onto the
eyepiece. Attach your 35 mm camera body to the T-Ring. Ultima spotting scopes have fixed apertures and, as a result, fixed f/ratios. To properly
expose your subjects photographically, you need to set your shutter speed accordingly. Most 35 mm SLR cameras offer through-the-lens metering
which lets you know if your picture is under or overexposed. Adjustments for proper exposures are made by changing the shutter speed. Consult your
camera manual for specific information on metering and changing shutter speeds.
Hint: Most photos will be the sharpest and brightest when using the lowest power on the zoom eyepiece.

With Digital Cameras:
Since digital cameras (not digital SLR cameras) do not use the T-system to mount cameras to lenses, spotting scopes, telescopes, etc. you need a
different way to be able to use them to take photos. Celestron offers a Universal Digital Camera Adapter (Model # 93626) which makes it easy to
attach a digital camera to your Ultima spotting scope.
