The SPC900 and SPC880 Adapter for Straight Through Finders connects SPC900, SPC880 and Toucam Pro I & II cameras to SkyWatcher & Clones 9 x 50 straight through finders.
Most Celestron finders are the same as Sky-Watcher, and have 11 fine threads cut into the rear of the finder tube.
However some are different – Simply remove the eyepiece and holder to check.
Please contact us prior to purchase if you are unsure 🙂
Tests have confirmed that guiding is successful at focal lengths of up to 1500mm and more.
Stability is excellent if screws are tightened firmly and cables tied up.
Using the finder as a guidescope reduces the weight and complexity of your imaging setup and the wide field of view guarantees finding suitable guide stars.
Adapters are near parfocal with visual focus of the finder.
