1m f5.4 Dream Ritchey-Chrétien Cassegrain

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 an optimized field flattener for superb full-field correction, no field distortion and 100% illumination of the 135mm diameter field required for the back-thinned 10k detector; 10560 x 10560 pixels, 9µ pixels.
Contact Dream for custom solutions for your project. More than 80% of what Dream produces is custom.

1.007 square degree field

This cutting-edge telescope features;
- Dream's zeroDELTA engineered lightweight mirrors: 3-6x lighter than conventional mirrors, used for both M1 & M2, no print through and the same low MSF errors of solid mirrors, due to Dream's world-leading push to produced the most highly engineered lightweight mirrors.
- 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. Dream is the only company in the world that has fully addressed ***mirror seeing.
- Designed for use with the field flattener optimized for 350-800nm waveband, or without, 350nm-2000nm. Contact Dream for custom solutions.
