The Celestron 6 inch Schmidt

The Celestron 6 inch Schmidt Cassegrain OTA produces sharp, detailed views of the planets and moon, and it has enough light gathering power to see fainter deep sky objects . I used to have a high quality 5" reflector, and this scope made a very noticeable difference when viewing the rings of Saturn and the cloud bands of Jupiter.

Excellent value

I am very happy with this telescope. After much research, I concluded that the Celestron 6" OTA offered the best bang for the buck. It also fits/works well on an Explore Scientific Twilight 1 mount, without being too heavy to lug around. OPT offered the best overall deal.

Great little scope

I got this to mount on my iOptron miniTower for outreach and just a small portable scope and it really fits the bill. Views of Saturn were great, easily saw the Cassini Division.

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.
