... no more difficult or complicated than using an off-axis guider if one follows a few simple rules. • The most fundamental mistake is to attempt to mount the guide scope directly to the primary tube. A guide scope is just too heavy and will bend the main tube in all sorts of random ways when in use. • ...

... tronomic eyepiece is being used without a Barlow lens 8.1 with a position angle of 210 degrees and a separaand cannot effectively measure dim stars or ones with tion of 0.3 arc seconds (Mason 2009). This separation small separations. The choice of neglected double was just within the Dawes limit for ...

... In the dark night sky, we see many stars and it looks like some stars are very close together. Proximity of two stars is apparent in some cases due to the effect of projection of stars according to an observer. Nevertheless, we also see stars that are gravitationally bound and their proximity on the ...

... degree of further rotation aligns the arrow and Sun and you have one solar day (24 hours) since the last time the Sun was on the meridian. The geometry of the situation also shows that the Earth moves about 1 degree in its orbit during one sidereal day. That night the Earth observer will see certain ...
