... These values are functions of the geographical (geodesic) latitude and the height of the point above the sea level. ... The option also permits to solve the reverse problem — to calculate approximate values of observatory latitude and its height above the sea level depending on the introduced values of dxy and dz. ... It should be mentioned that low precision of dxy and dz for some observatories in the list maintained by MPC leads to negative value of height above the sea level for some of them. ...

... Module Crystal was launched from Baikonur on May 23, 1990 by the LV Proton-K. The total length of the module is 11.9 m; maximum diameter 4.3 m; mass at the launch 19500 kg. ... It has two panels of the solar batteries with the area equal to 72 m 2 (8.4 kW). They are of a new modification (repeated opening/closing is admissible) and one of them is transferred to the module Kvant. ... Besides, it has two additional docking ports for interaction with the reusable ships (Buran, later - Shuttle). ...

logd25 is the decimal logarithm of the length the projected major axis of a galaxy at the isophotal level 25 mag/arcsec 2 in the B-band (this is the diameter of the galaxy if it is a disk). Many papers were devoted to the study of diameters and specially to the reduction to the standard system defined by the isophote at the brightness of 25 B mag/arcsec 2 . ... The shape of the galaxy at the same isophotal level (B=25 mag/arcsec 2 ) is defined in the parameter logr25 . ... HyperLeda . ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...
