32" f4.2 Dream Ritchey-Chrétien Cassegrain

1.05 square degree field00

Like all Dream instruments this extremely efficient, low-maintenance, powerful & high-performance Dream true R-C telescope is designed from the ground up for robotic/remote use. It comes with a purpose-built field flattener for superb full-field correction and 100% illumination of a 61.4mm x 61.4mm detector (CCD231-84). Contact Dream for custom solutions for your project. More than 80% of what Dream produces is custom.

This cutting edge instrument 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.

Both M1 and M2 are engineered, lightweight mirrors, finished based on high-resolution interferometry data from vertically-tested mirrors, while each mirror is in its final carbon fiber athermal mirror mount. Raw data is provided to the customer.

This telescope is optimized for 400-750nm but a custom solution can be quickly optimized for different wavebands.

The camera achieves -100°C cooling without the hassles of LN or cryo-cooling.
