The 7704 focal reducer set converts the Borg
line of scopes into
fast
astrographs optimized
for digital sensors, yet capable
of covering a full 35mm frame:
- 77EDF6.6 -> 77EDF4.3
- 101EDF6.4 -> 101EDF4.1
- 125EDF6.4 -> 125SDF3.9
The 7704 set includes a built-in filter
holder as well as a camera rotator for flexible
image composition.
Provision for the attachment of filters is via a
55mm diameter filter thread on the front reducer
lens assembly (for semi-permanent filter
installation) and via an easily removed filter
holders which accomodate 52mm or 48mm filters. A
camera shutter cable can be attached to the focal
reducer assembly to make removal of the filter
holder a simple operation which does not disturb
the optical train. Additional filter holders
[7518]
are available for quick changes between
filters.
