October 14, 2006 ---------------- Version 3.1 ----------- As of this version, XmTel is considered stable for routine use. and it is useful for the control of telescopes for both amateur and professional uses. ... XmTel does not yet include the suite of pointing corrections that are already in the menu system (but disabled). ... With the offset correction a well-aligned small telescope will point to arc minute accuracy and well enough to put an object in a CCD camera field of view. ...

... A theory suggests that a certain sub-class of gamma-ray bursts all have the same absolute magnitude. ... The author claims that this absolute magnitude is so different from that in the previous sample that this must belong to a new sub-class of gamma-ray bursts. ... To do this, there needs to be some feature in their spectra which correlates with their absolute magnitude. ... Consider a telescope which is continually monitoring a star, looking for transits due to planets orbiting this star. ...
