SLR PHOTOGRAPHY
To use an SLR camera and your spotting scope for photography,
you will shoot through the zoom eyepiece while it is attached to
the spotting scope. To prevent damage to the spotting scope,
eyepiece or camera make sure the eyepiece lock collar is secure
during each stage of the setup.
1. Remove the eyecup from the zoom eyepiece. With the
eyecup down, rotate it counterclockwise to remove it
from the eyepiece. This will expose the threads under
the eyecup (Fig. 10a).
2. Thread the included T-adapter ring to the threads
exposed on the eyepiece in step one above (Fig. 10b).
3. Thread an optional T-ring for your make and model of
camera onto the T-adapter ring (Fig. 10c)
4. Attach your SLR camera body to the T-ring (Fig. 10d).
The Regal M2 spotting scopes have fixed apertures and as a
result fixed f/ratios. To achieve the proper exposure for your
photographs you need to set the shutter speed accordingly.
Most cameras offer through-the-lens metering which will let
you know if your picture is under or overexposed. Consult your
camera manual for specific information on metering, changing
shutter speeds and other settings.
