May 2013 Update on APO Imager Proposal J. Huehnerhoff, W. Ketzeback (APO) In March 2013, a proposal for an imager on the APO 3.5m telescope was presented to the users committee. ... From this feedback it was determined that the most important properties of this imager should include good throughput, good spatial resolution, fast readout, and capability to use narrow band filters (both existing and new). ... The CCD allows many binning modes but 2x2 or 3x3 is expected to be used in normal operation. ...

Aboriginal and Torres Strait Islander people developed complex knowledge systems around the sun, moon, and stars. Stellar positions and properties (such as declination, colour, brightness, and scintillation) were important for navigation, calendars, economics, and time-keeping. Transient astronomical phenomena (including comets, meteors, eclipses, and aurorae) reinforced sacred law and cultural practices and served as a moral charter. ...
