Retrofitting a 13" Dobsonian By Dave Aucoin . ... I had retrofitted the scope, not the older box and tube, but the newer tube design, to break apart to fit in my then Chevy Chevette. ... Then my girlfriend mentioned that I should build up the pads with blocks so that the mirror box would slide properly over the Teflon and not catch on the ZHRB. ... Now the lower block, attached to the mirror box has 2 angles that have to be used for the tube to reach the upper clamp block without too much bending. ...

Sil'chenko Received April 28, 2011 ** Sternberg Astronomical Institute, Universitetskii pr. ... We have analyzed the optical structure of these galaxies using SDSS (Sloan Digital Sky Survey) surface photometry, measured the colors of the rings, and compared the radial localizations of the ring structures in the optical and ultraviolet spectral ranges. ...

UT date of the measurement finish in YYYY-MM-DD format UT time of the measurement finish in hh:mm:ss format Average flux in A aperture Average flux in B aperture Average flux in C aperture Average flux in D aperture Normalized variance of flux in A aperture Normalized variance of flux in B aperture Normalized variance of flux in C aperture Normalized variance of flux in D ...
... It appears that, billions of years after the big bang, following the formation of galaxies, some form of dark energy that is causing the expansion rate to accelerate overtook the Universe. ... The transition from big crunch to big bang automatically replenishes the Universe by creating new matter and radiation. ... By dispelling the myth that the big bang is a beginning of space and time, superstring theory opens up new possibilities for the cosmological history of the Universe. ...
