Celestron 1.25" Universal T-Adapter
The Celestron T-Adapter, Universal - 1.25 in
fits (drop in style) any type of telescope that uses a 1" focuser or visual back.
allows you to attach your 35mm SLR camera to the prime focus of your telescope or spotting scope. This arrangement is used for terrestrial photography and short exposure lunar and planetary photography. It can also be used for long exposure deep-sky photography when using a separate guidescope.
Before even started, you have to get an appropriate T-Ring
for your camera body (#93402 for Nikon
& #93419 for Canon EOS
are sold separately), then remove the lens from your camera and attach the T-ring in its place.
