Rumors of a Strange Universe . ... Such claims are not usually popular with astronomers, though, because lambda is so unlike known universe components, because lambda's value appears limited by other observations , and because less-strange cosmologies without lambda have previously done well in explaining the data. ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

Magnification (Power) And Using Eyepieces . ... To determine power in a telescope, divide the focal length of the telescope by the focal length of the eyepiece. By exchanging an eyepiece of one focal length for another, you can increase or decrease the power of the telescope. For example, a 25mm eyepiece used on a telescope with a 1000mm focal length would yield a power of 40x (1000 / 25 = 40) and a 10mm eyepiece used on the same telescope would yield a power of 100x (1000 / 10 = 100). ...

METAR Wishlist Following is a list of items that I'd like to add to METAR or that others have requested. ... It'd be nice to have a lot of METARs which encompass various weather condition which we can test against. ... Sites around the world use similar (but slightly different) formats for their METARs. There is always a METAR format the parser will fail on. Calculate Heat Index and/or Wind Chill Both would be fairly easy to do, provided you get the formulas correct. ...
