SPTIME takes an input source spectrum, either a reference blackbody, power law, or a user spectrum, a background ``sky'', observing parameters such as exposure time, central wavelength, seeing, airmass, and moon phase, instrument parameters such as aperture sizes and detector binning, a description of the spectrograph, and desired output. ...

Star formation is often best manifested by bright H II regions.These are regions of hydrogen which have been ionized by ultraviolet photons which are emitted from massive stars (typically stars more than 20 times the mass of the Sun). ... A narrowband filter image centered on this wavelength will then readily reveal these H II regions and hence the current sites of star formation in a galaxy, The luminous blobs that can be seen here are all H II regions . ...

APO has implemented a prototype guide camera for the 0.5-m Telescope. ... Guiding will continue unless a guide star is lost (clouds, high background from moon or twilight, or the telescope is slewed to another field). ... ACP maintains the guiding for the same field and will not re-acquire a guide star unless the field moves (example excessive tracking jumps) or ACP needs to re-center the object. ... The prototype guider is in shared-risk mode. ...
