A liquid mirror space telescope is a concept for a type of reflecting space telescope which uses a reflecting liquid such as Mercury element mercury as its primary reflector. ref Citation title Liquid Mirror Telescopes journal American Scientist volume 95 year 2007 pages 216 223 author Paul Hickson ref There are several designs for such a telescope 1. Twirled Pail A pair of objects, one the mirror assembly and the other a counterweight possibly containing a camera assembly, are spun up to induce centripetal acceleration on the surface of the mirror assembly. 2. Half Toroid A hollow toroid torus a doughnut or spare tire shaped object is spun up to maintain centripetal acceleration against the inside wall. The camera assembly sits in the center. The torus width is arbitrarily large. Optional other pieces include a large flat mirror in the center to allow randomly orienting the mirror without frequently changing the axis of spin. 3. Balloon A balloon with a reflective liquid on the inside is spun up and it deforms itself into a parabolic shape. A flat mirror on the inside reflects light to the concave surface. Regardless of the specific configuration, such a telescope would be similar to an earth based liquid mirrortelescope. However, instead of relying on Earth s gravity to maintain the necessary parabolic shape of the rotating mercury mirror, it relies on artificial gravity instead. Other possibilities for inducing a parabolic shape in the reflecting liquid include magnetic fields ...

Regression bar Segmented regression is a method in regression analysis in which the independent variable is partitioned into intervals and a separate line segment is fit to each interval. Segmented or piecewise regression analysis can also be performed on multivariate data by partitioning the various independent variables. Segmented regression is useful when the independent variables, clustered into different groups, exhibit different relationships between the variables in these regions. The boundaries between the segments are breakpoints .

The Steward Observatory Mirror Lab has been making mirrors for large Gregorian telescopes at least since 1985. In the Gregorian design, the primary mirror creates an actual image before the secondary mirror. This allows for a field stop to be placed at this location, so that the light from outside the field of view does not reach the secondary mirror. This is a major ... more details
The California Extremely Large Telescope CELT was a proposal for an extremely large telescope design first proposed in the 1990s by a consortium of Californian Universities. ref cite journal date 8 November 2002 title California Astronomers Eye 30 Meter Scope journal Science volume 298 issue 5596 pages 1151 1153 url http www.sciencemag.org cgi content summary 298 5596 1151 doi 10.1126 science.298.5596.1151 pmid 12424344 last1 Irion first1 R ref The design was for a segmented 30 m diameter astronomical telescope.

The CELT was one of the earlier and more successful proposals for Extremely large telescope s. The optical design for CELT is a Ritchey Chretien two mirror system, with a segmentedmirror mosaic with 1080 segments. ref name pressrelease This rather naturally provides a large, 20 arcminute field of view with less than 0.5 arcsecond images 100 enclosed energy . This focus is free of Coma optics coma and only suffers from astigmatism , which grows quadratically with field angle. The primary will be convert 30 m ft in diameter, and for compactness, the primary f ratio will be f 1.5. The final focus will be f 15, delivering a final focus with about 2 mm arcsecond as its plate scale. Such a gianttelescope produces very large seeing limited images, a challenge for the design of seeing limited scientific instruments. The 20 arcminute field is convert 2.6 m ft in diameter.
