41112 Photoadapter Push Fit 49.5
41120 44~42 Step Ring
41123 44~28 Step Ring
Hexagonal key 1.27mm
The 41112 Photoadapter Push Fit 49.5
is designed for use with the HDF T
40862 zoom eyepiece converting ES,
GS, MM3 and IS telescopes into long
focal length telephoto lenses for
telephotography or digi-scoping.
Assembly and Fitting (all camera types)
1. Make sure the correct eyepiece is
fitted securely to the telescope.
2. Set the eyecup to the down position.
3. Fit the correct step ring to the
photoadapter; 44~42 for SLR/
compact system cameras, 44~28 for
suitable compact cameras.
4. Pre-set the eyepiece magnification to
minimum.
5. Place adapter over the eyepiece
and push down until the internal
wall contacts with the end of the
eyepiece.
6. Hold the main section of the adapter
secure and tighten the locking screw.
7. (SLRs & CSCs) Fit an appropriate
T-mount between the photoadapter
and the camera body.
8. (Compatible compact cameras)
Connect the camera lens mount
to the 28mm thread on the
photoadapter.
Focal lengths with HDF T 40862
eyepiece
ES 80 - 1000mm ES 100 - 1350mm
GS 52 - 600mm GS 665 - 800mm
MM3 50 - 600mm MM3 60 - 750mm
IS 60 - 750mm IS 70 - 800mm
1. Focal lengths listed are approximate and
based on 35mm SLRs. Many SLRs and
CSCs use different sized image sensors
so a telephoto conversion figure must be
calculated separately.
2. Focal length is calculated at lowest
magnification setting.
Notes
1. If you find the camera is at an odd angle
when attached - loosen the locking ring,
rotate the camera into line and re-tighten.
2. Focusing is facilitated on the telescope.
3. Camera may need to be operated in manual
mode with shutter locks disengaged where
necessary.
4. The high magnification to aperture ratios
result in slower shutter speeds compared
with conventional telephoto lenses so
choose an IS0 setting of 400. For 35mm
SLRs 400 ASA film is recommended. If
possible use a cable release or remote
control to reduce camera shake when
operating the shutter.
