The celestron erect image star diagonal is suitable and reliable and fits well with your daily purpose. This is a well made diagonal that screws right onto the telescope. It serves the function of the visual back and the star diagonal, and does NOT require any additional parts to attach to Celestron SCTs. It is precision machined to achieve and hold good optical alignment. The mirror surface is covered with the same high performance xlt coatings used on Celestron ’s best telescopes, and the result is a sharp, bright image that will satisfy the most discriminating amateur astronomer.
The larger 2” barrel allows you to see a bigger percentage of the telescope’s light cone, which works wonders for capturing faint deep sky objects with low surface brightness. It comes in an elegant, metal, foam-lined box.Why We Like This:
