Digiscopy
Digiscopy is loosely defined as using a digital camera to photograph the
image exiting a scope (binoculars, spotting scopes, telescopes, etc.) Here is a
great resource for
learning about practical digiscopy. My first goal is to be able capture a
digital image of Jupiter and its four largest moons. Along with photos of the
moon, this will be my first introduction into
astrophotography.
Two instruments for digiscopy use:
- Konus 20X x 80 mm binoculars (Model
2110
Giant 80)
- Barksa 20-60X x 60 mm Blackhawk weatherproof spotting scope
(Model
AD10350)

The spotting scope looks like it will be the easiest to couple with
one or more of my digital cameras especially since Barksa already has
two different methods for mounting cameras to the scope;
- Barksa digiscoping adapter (Model
AF10540)
- Barksa SLR digiscoping adapter (Model
AF11286)

The binoculars have and exit pupil of 3.83 mm but I don't know the eye
relief. Their eye piece is also very short which makes it difficult to mount a
camera adapter.
The spotting scope looks like it will be the easiest to couple with one or
more of my digital cameras. The spotting scopes exit image specifications are:
@ 20X magnification, 3 mm exit pupil with 18 mm eye relief
@ 60X magnification, 1 mm exit pupil with 15 mm eye relief.

After some searching on the web, I decided that my
first attempt at digiscopy would be with an adapter that I could use on
my binoculars and my spotting scope. I chose a Baader Microstage II
clickstop adapter. This adapter allows me to:
- probably use more than one camera,
- use it one my binoculars due to its small size and
- swing the camera out of the way when spotting and then
have it swing perfectly bak into proper adjustment when ready to
shoot photos.
