Using QuikAdapt for Eyepiece Projection with a DSLR
For DSLRs, prime focus astrophotography is the prefered method (see adapter below) but for
planets and other small objects, especially with short focal length telescopes, the image may be too
small to show much detail. Eyepiece projection with the camera lens removed from the DSLR
provides a lot more magnification for small objects. SLR camera body is attached to the QuikAdapt
using the tripod screw hole on the bottom of the camera and the white nylon thumb screw
(provided). The crossbar (see other side) is not needed and should be removed.
In eyepiece projection the telescope's objective lens or mirror creates a prime focus image just in
front of the eyepiece. The eyepiece collects the light from the prime focus image and reimages
(projects) it onto the sensor in the DSLR. The effective magnification boost (M) obtained by
eyepiece projection is calculated from the focal length of the eyepiece lens (Fe) and the distance
from the eyepiece lens to the SLR sensor (Ds) as
M = (Ds-Fe)/Fe
The smaller the focal length of the eyepiece (Fe) and/or the greater the distance between the
eyepiece the SLR sensor (Ds) the greater the magnification boost from eyepiece projection. Ds can
be roughly measured from where the eyepiece lens body joins it's eyepiece tube (the part of the
eyepiece that slides into the telescope 1.25 or 2 inch draw tube) to the camera's sensor plane.
Prime Focus Astrophotography with
Optional QuikAdapt SLR Prime Focus Adapter
Attach SLR adapter to QuikAdapt instead of an eyepiece for prime focus astrophotography
using digital and film SLR cameras with camera lens removed. Fits 2" telescope eyepiece
drawtubes. The prime focus method uses your telescope as a very long camera lens in place of
the SLR lens. SLR camera body is attached to the QuikAdapt using the tripod screw hole on the
bottom of the camera and the white nylon thumb screw (provided). The crossbar (see other side)
is not needed and should be removed.
