The 41111 Photoadapter Push Fit 44 is
designed for use with HDF T 40810,
40809, HDF 40862

& HR2 40933

eyepieces converting HR, GS, ES, MM3
& 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.

GS 52 - 650mm

GS 665 - 900mm

MM3 50 - 650mm IS 60 - 800mm
IS 70 - 900mm

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 for HR2 40933 calculated at

lowest magnification setting.

Using other eyepieces
The photoadapter can be fitted to
smaller diameter eyepieces by replacing
the 44mm sleeve fitted as standard with
either of the following:
a. 41117 reducer sleeve 44~40 for

connection to 40918S eyepiece

b. 41118 reducer sleeve 44~37 for

connection to HDF 40810

and

40809

eyepieces

F = Fold down rubber eyecup

Using the 41117 reducer sleeve
1. Make sure the correct eyepiece is

fitted securely to the telescope.

2. Unscrew the locking ring on the

photoadapter, remove the 44mm
sleeve and insert the 44~40 reducer
sleeve. Re-connect and tighten the
locking ring.
