- Wonderful spotting scope
The C6 SCT OTA is a quality product. Many years ago producing an SCT was said to be prohibitively expensive. I remember fliers circulating in either late 1969 or 1970 announcing the Celestron C8 SCT for I believe $795. This was quite a breakthrough in mass production technology at an affordable price.
I purchased this 6 Celestron SCT to be used mainly as a high power spotting scope, a task it performs exceedingly well. This particular unit needed to have its corrector cleaned and while at it, I relined the baffle tubes to reduce stray light to a minimum. Now it excels in powers that other high priced conventional refractor spotting scopes only dream of. Using my binocular viewer the views are superb in the 90x to 360x range- sharp with high contrast and excellent color correction.
By the way, for terrestrial spotting I often use a 90 degree correct image diagonal which is superior optically to the 45 degree version. The included dovetail plate has 1/4x20 threads that allow the OTA to be mated with a HEAVY duty tripod.
This may be the ultimate spotter if you want a scope that can reach farther than even the most highly touted standard spotting scopes.
