We're offering Regular Tours (a presentation on astronomy geared to a general audience, followed by a tour of the observatory and (hopefully!) observing of several objects, which may include the Moon, planets, nebulae, star clusters and perhaps galaxies), and Kids' Tours (a more interactive presentation specially aimed at youngsters plus the observatory tour and observing) as in prior years. ...

... astro-ph . ... We present the goals and preliminary results of an unbiased, near-infrared, narrow-band imaging survey of the First Galactic Quadrant (10deg<l<65deg ; -1.3deg<b<+1.3deg). ... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ...

The Hubble orbiting telescope. The Earth's atmosphere, while transparent to visible light, absorbs most "electromagnetic radiations" which belong to the same family as light: parts of the infra-red (IR) and all of the ultra-violet (UV), X-rays and gamma rays. ... The Hubble telescope , in low Earth orbit, overcomes such limitations, in the visible range and in part of the UV. ... Some satellites specialize in observing the Sun, such as the Japanese Yohkoh and NASA's SOHO . ...

Use of Charts. by Stefano Pesci . ... The charts are used by some amateurs in Italy and are now available to world-wide amateurs interested in supernova hunting. ... A reference of the galaxy observed is crucial to determine if any suspect stars are visible or not. ... What do the charts show * --------------------------- Galaxies are shown as a set of lines, sort of isophotes. ... CCD imaging gives a very deep view of the galaxy and some very faint stars may not be shown on the chart. ...

... We also take care to characterise the flat fields, especially their colour dependence, to very high precision which enables high precision photometry even without autoguiding. ... The Blue Diamond Effect The blue diamond effect is caused by surface imperfections on the silicon chip introduced during manufacture, resulting in a repeated large scale pattern in the flat field at blue wavelengths. ... We can remove the blue diamond by using a colour appropriate flat field produced in the lab. ...
