Over the last 15 years or so there has been a huge increase in the popularity of astrophotography with the advent of digital SLR cameras and CCD imagers. These have enabled astronomers to take many images and, indeed, check images as they scan the skies. Processing techniques using computer software have also made adevelopinga these images more accessible to those of us who are achemically challenged!a And letas face it a some of the pictures you see these days in magazines, books, and on popular web forums are, frankly, amazing! So, why bother looking through the eyepiece you ask? Well, for one thing, setting up the equipment is quicker. You just take your ascope out of the garage or, if youare lucky enough to own one, open the roof of your observatory, align the ascope and off you go. If you have an equatorial mount, youall still need to roughly polar align, but this really takes only a few moments. The aimagera would most likely need to spend more time setting up. This would include very accurate polar alignment (for equatorial mounts), then finding a guide star using his or her finder, checking the software is functioning properly, and c- tinuous monitoring to make sure the alignment is absolutely precise throu- out the imaging run. That said, an imager with a snug aobsya at the end of the garden will have a quicker time setting up, but then again so will the avisuala observer.A Pocket Field Guide Stefan Rumistrzewicz ... this system, affectionately referred to as a#39;the tuning Fork, a#39; was first conceived by edwin hubble in 1926 and has undergone several revisions since (most notably by de vaucouleurs). nevertheless, anbsp;...
