A large batch of 5.75" cellular secondary mirrors
have been produced. These cellular mirrors will be used for any
future orders of the 16" Dream Astrographs. The original
5.5" monolithic secondaries were designed to fully illuminate
CCD chips as large as 25mm x 36mm. The monolithic 5.5" secondary
weighed 3.7 lbs. The new 5.75" weighs ~1.4 lbs and is large
enough for CCD chips as large as 36mm square. It is the "little
brother" of the 7.75"
cellular secondary, used on the 24" f3.5 Dream Astrograph. |
