... Many of the beautiful photos in astronomy textbooks were taken by amateur astronomers using everyday camera equipment. With Comet Hale-Bopp fast approaching, now is a perfect time to learn the not-too-difficult science and art of still-camera astrophotography. ... The Pentax K-1000 is one such camera. ... Data should include date, location, sky conditions, camera and lens specs, film type, and the time, subject, and length of each exposure. ... Slides show exactly what you photographed. ...

... Tonight's Sky . ... Star Atlas . ... The double star 54 Leonis, spiral galaxy NGC 3198, and emission nebula NGC 3199 . ... Fun with double and variable stars . Splitting tight double stars and tracking the brightness changes of variable stars are fun activities unimpeded by sky glow. ... Double stars . ... Like double stars, variable stars are not as adversely affected by light pollution as some other sky targets are. ... Pulsating variable stars actually expand and contract, like a beating heart. ...

... The obscuration due to dust and the high stellar density in our Galaxy blocks our optical view of the extragalactic Universe over 20% of the sky, somewhat less in the infrared, the "Zone of Avoidance" (ZOA). ... Mapping hidden galaxies over a range of redshifts also allows the connectivity in three dimensions of large-scale structures across the Galactic plane to be explored. ... 9 Galaxies were uncovered in this precursor region, 6 previously known from HIZOA, and 3 new HI detections. ...
