MESSENGER image of comet ISON (C/2012 S1) during its closest approach to Mercury. At that time, ISON was approximately 22.5 million miles (36.2 million kms) from MESSENGER and 42.1 million miles (67.8 million kms) from the Sun. The image is 7 by 4.7 in size and has been slightly magnified and smoothed to enhance the faint tail of the comet. The tail was oriented at an angle to MESSENGER at the time and is foreshortened in this image; however, some faint structure can still be seen. ...

... Alfa_ang is a GUI for the rotang routine. The purpose of this routine is to calculate the optimum rotation angle for ALFA given the RA and Dec of a source and the date and time of the observation. The routine also returns the azimuth and zenith angle of the telescope at the requested time, thus it can be used to find the correct rotation angle and azimuth for the Fixed Azimuth Drift Scan observing mode used by the AGES drift precursor observation. ...
