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 ‘developing’ these images more accessible to those of us who are ‘chemically challenged!’ And let’s face it – 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 ‘scope out of the garage or, if you’re lucky enough to own one, open the roof of your observatory, align the ‘scope and off you go. If you have an equatorial mount, you’ll still need to roughly polar align, but this really takes only a few moments. The ‘imager’ 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 ali | | Pindex | Book 2010 |
