Efficient use of the WFPC2 requires an understanding of the overhead times of the instrument. ... The start of an alignment requires 1 minute overhead in order to synchronize timing with a major frame (all commands to the instrument take place on major frames which last 1 minute). ... If scans are being performed, another minute of overhead is required and, if images are requested in real-time, another 2 minutes must be added to the alignment end. ... The readout time for an exposure is one minute. ...

... A star party is a gathering of amateur astronomers who set up their telescopes and observe the dynamic night sky. ... Star parties are best scheduled during first quarter and waxing gibbous Moon.

. Computer Ephemeris. Sidereal time. Explanations. Each row contains at 0h of Universal time: month, day, real sidereal time (hours, minutes, seconds), mean sidereal time (only seconds, as a rule, hours and minutes are the same as in real time) and nutation in right ascension: long periodic (with periods greater than 35 days), and then short periodic (periods less than 35 days). Standard IAU 1980 nutation theory is used.
