... I used Ѕ inch thick Appleply plywood throughout. ... The mirror box is a little unusual. ... The original design uses a fiberglass tube to connect the mirror base plate to the top ring to form the mirror box. ... I decided to build the mirror box like a standard secondary cage instead, using aluminum tubes with push-in inserts. ... All three tubes are retained at the mirror box and the secondary ring using nine, 1-inch thick Appleply clamps, three at the secondary and six on the mirror box. ...
... I will touch upon the following points: fast evolution of the sizes of quiescent (elliptical) galaxies between z = 2 and z = 1; prolonged star formation histories of dwarf spheroidal galaxies in the Local Group; apparent lack of external sources of cold gas accretion for the nearby spiral galaxies; old stellar ages and magnesium overabundance of the large-scale disks of nearby lenticular galaxies. ... This discovery has challenged the recognized scenarios of elliptical galaxy evolution. ...
