UX Tau A's protoplanetary disk extends to a radius of 120 AU (1 AU = the distance between the Earth and the Sun) with a high spatial resolution of 0.1" (arcsecond) Left: Near-infrared intensity image of UX Tau A. White is the brightest, and then red. ... Its west side (on the right) is a little brighter than its east side; this indicates that the inclination of the disk is in the east-west direction and that its west side is closer to the observer (see figure on the right). ...

Polar Alignment Using The Star Drift Method . Articles | ... This method with, a little practice, can give you reasonable polar alignment within one half hour. ... If the star drifts northward, your scope is west of the pole. ... Remember that as your adjustments get you closer to the pole, the star will drift slower and you must wait longer to detect a north-south drift. If the star drifts south, you are east of the pole and you must turn the mount towards the west. ... www.astronomy.net . ...

... For reliable estimation of the accuracy of asteroid CCD observations we usually consider from ten or more various NUMBERED MINOR PLANETS (NMPs) observed during several nigths per month (more then 50 positions). ... They can be considered as an indicator of accuracy of the CCD positional observations with given MPC code. ... For any NUMBERED minor planet the (O-C) values must be zero if the errors of observations and the errors of its theory are absent. ...
