... We describe the construction of convolution kernels that allow one to generate (multiwavelength) images with a common PSF, thus preserving the colors of the astronomical sources. We generate convolution kernels for the cameras of Spitzer, Herschel Space Observatory, Galaxy Evolution Explorer (GALEX), Wide-field Infrared Survey Explorer (WISE), ground-based optical telescopes (Moffat functions and sum of Gaussians), and Gaussian PSFs. ...

... An OBJECT column gives the name of the object observed (usually a star name). ... In critical cases, it is common practice to measure sky on two or more positions around a target object, and these positions must be identified. ... A general treatment of this problem requires a column called OBJECT, bearing the usual name of the object (as in the star tables); a column labelled STARSKY, to distinguish between star+sky, star alone, or sky alone; and additional columns to identify the sky position. ...

The rotation type specifies the meaning of the rotation angle. Only Object and Horizon are typically used for science (or None if your instrument does not have a rotator). ... Mount is typically used for engineering. ... Mount: rotator angle used by the rotator axis controller. ... For an instrument with a rotator: if you specify a rotation type of None and the rotator is moving then it will be halted at approximately its current position; this feature use used to implement a controlled stop. ...

The sky inhabitants - the constellations. ... The constellations of Zodiac. The constellations of Zodiac are very popular. ... They were counted from the point of vernal equinox. ... As a result all the Zodiac row of constellations as if displaced in the two positions the count traditionally begings from the constellation where the point of a vernal equinox is. ... That is why the Sun comes to each Zodiac sign two - five weeks before the time when it comes to the constellation of the same name. ...

... The J, H and K bands are characterized by a bright background, such a background is mainly due to the emission of atmospheric lines and of thermal radiation. ... If the source cover a large fraction of the slit, spectra off-source must be observed to adequately sample the sky background. ... The on chip integration time (time spent in each position of the slit) must not exceed 40 seconds in J and H bands and 60 seconds in K band. ... We suggest a sequence of 10 for each elementary integration time. ...

You Can Make Stellar Images Brighter . Articles | ... A few months ago I wrote an article titled "You Can’t Make Them Brighter". So why am I now writing that you can make them brighter. ... The image of a focused star is actually a small disk called the Airy disk, named after the 19 th century scientist Sir George Airy. ... For a given aperture, a smaller Airy disk means that the light is focused to a smaller disk and is therefore brighter. ... www.astronomy.net . About Astronomy Net | ...

...

... Although they would have appeared as two of the brighter galaxies on the night sky, the opaque dust of the central band of our Milky Way Galaxy had obscured them from being seen in visible light. ... An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. ...

... The PCIPS image processing system (Smirnov & Piskunov 1994) has been in development since 1991; the current version is 2.01. ... Key features of the system include: (1) an intuitive graphical user interface (GUI), (2) all functionality is provided by external application modules, which are easily added to the system as they are developed, (3) there is an application program interface (API) for development of custom applications, and (4) the code runs on practically any Intel-based PC. ...
