32"(CA) f4.2 Dream Ritchey-Chrétien Cassegrain

This extremely efficient, powerful and high-performance Dream R-C telescope comes with a purpose-built 2-lens field flattener for superb full-field correction and 100% illumination of the Andor iKon-XL 231 camera listed below, over a nearly 90mm field diameter.

This cutting edge telescope features;
- Dream's zeroDELTA engineered lightweight mirrors for both M1 & M2, with no print through.
- Dream's engineered carbon fiber (CF) and CF skinned sandwich core components, producing an ***athermal telescope: 95% of the structure weight is Dream's carbon fiber with only 5% conventional metals - ***settingetheestandard for truly carbon fiber telescopes.
- Dream's FAST: Filtered Air System Technology: fills the telescope with clean air, providing the lowest ***possibletmaintenancetbecause it keeps optical coatings clean, requiring both less cleanings and fewer re-coats, ***astwelltastthetshortest possible Thermal Time Constant.
