What is a Family ASTRO Take-Home Activity? These activities (games and kits) were initially designed for Astronomy Event participants to take home and do on their own, thereby providing an opportunity for continued learning at home with family and friends. ...

Adjust the focus of the crosshairs of the alignment telescope by rotating the eyepiece. ... Record the position of the alignment telescope's crosshairs on the secondary mirror's dimple (e.g. by making a sketch). ... Adjust the mirror until it is collimated: . ...

Here is one CCD image of the SN. ST7 image format. Dark and flat corrected, Mar 19,1998 at.01.11 UT, yellow filter, temp -20c, 600s track and accumulate exposure (20x30s). The telescope used is 150/2063mm refractor. ... The next image was taken at 29.3.1998 01.27 UT, CCD ST-7, 600 s.

VISTA is a 4-m class wide field survey telescope for the southern hemisphere, equipped with a near infrared camera (1.65 degree diameter field of view at VISTA's nominal pixel size) containing 67 million pixels of mean size 0.34 arcsec and available broad band filters at Z,Y,J,H,K s and a narrow band filter at 1.18 micron. A wide field visible camera, if constructed, could also be used on VISTA. ... Tile . ... ESO VISTA Public Surveys . ...

... This image shows clearly the 3-D structure of this star formation region: a large cavity, created by the radiation pressure from new-born stars located in the brightest area of the image, lies within a huge cloud of dust and gas. Identified as a truly indepedent star cluster, NGC 1980 is associated with this well-studied star formation region, around the brightest star seen at the bottom of this image, Iota Ori. ...

... The files here will change whenever we have a new beta version that has had an error-free telescope run. ... A few things to note, however, about this "beta" edition: There is almost no error checking on the operation of the filter wheel. ... CCDops has better error checking than XmCCD, so if you have a Windows computer available, check your camera with CCDops when you use it for the first time. ... I have a built-in fixed delay to inhibit multiple requests too fast for the wheel. ...

... For each observed position the table contains designation of object as in file of observations, the time of observation, the number and name/ preliminary designation of minor planet supposedly identical with observed object, the values of O – C (observed position minus computed one) in right ascension and declination expressed in arcsec, the difference O – C between observed magnitude and computed one, the code of observatory in the Observatory list (see Observatories section). ...
