DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ... One formula is for aperture in inches the other is for aperture in millimeters. ... Aperture (inches) . ... 15.2 . ...

When using a large number of Virtual Hosts, Apache may run out of available file descriptors (sometimes called file handles if each Virtual Host specifies different log files. ... Unix operating systems limit the number of file descriptors that may be used by a process; the limit is typically 64, and may usually be increased up to a large hard-limit. ... If you system falls into 1 or 2 (above), then increase the file descriptor limit before starting Apache, using a script like #!/bin/sh . ...

... Limit of star magnitude. If you want to obtain best results, you should use reference stars not more dimly than limiting star magnitude of your telescope.

... Searches for Star Formation in Damped Systems . ... The objective was to measure the star-formation rates in these systems. However, no H emission was detected above our limits of Wm -2 , corresponding to star formation rates ( q 0 =0.5). ... For q 0 =0.5 our limits are in conflict with the star formation rates predicted under the assumption that the high- z DLAs are the fully-formed galactic-disk counterparts of today's massive spiral galaxies. ...

The upper limit to stellar masses is unclear, as is the relative importance of nature (stellar physics) and nurture (formation environment) to the limit. ... Despite some uncertainties in the linear growth rate, we conclude that these modes saturate nonlinearly at small and harmless amplitudes. Vigorous, optically thick winds driven by the Rosseland-mean opacity near 100,000 K are more likely to limit the main-sequence lifetime. ...
