They not only allow you to increase magnification on nights of good seeing, but decrease magnification when the air is less steady. First and foremost is the quality of the image it delivers. The reason for this is because RCs usually have a large central obstruction, which is how much light is obstructed entering the front of the telescope due to the size of the secondary mirror. While you can buy a manual equatorial mount and add dual-axis motors and a hand controller for astrophotography, these days most people prefer the computerized equatorial mount, like the Celestron Advanced VX Mount. Telescopes on computerized alt-azimuth mounts, like the Celestron NexStar SE do an amazing job of finding and tracking celestial objects for visual astronomy, and a user could even take quick pictures of the Moon and bright planets, but if you want to take astro-images of objects out of our solar system, it will require an equatorial mount. The APO design is more expensive than an achromat due to the increased number of lenses and/or the high-quality specialized glass that may be used to create all or some of the optics.

I am doing research with a 0.4m SCT and an old camera, and while I can do useful work, there's always something interesting that's about a magnitude too faint for my system (or I can detect it but not with enough SNR to get good data). While there are some exceptions to the rule, achromatic refractors use two lenses in their design, and while they are economical, achromats are only capable of focusing two out of three wavelengths of light. To keep from accidentally doing that, remove the finder scope all together and either replace it with a solar finder, which projects an image telling you when the Sun is in the field of view, or use the telescope's shadow to ascertain when the sun is in the proper location. },{ Next up is this 40-inch (1-meter) aperture telescope from Planewave. While there are still equatorial mounts on the market that have motors available for both axes (a minimum requirement for astrophotography), computerized mounts are more plentiful than ever and can be an economical choice since you won't have to worry about adding motorization to your manual mount later on. Standard extension from 1 meter to 2 meters. The optical system utilizes a Nasmyth focus through both. We recommend the Apertura AD 8" Dobsonian for its quality and included accessories.
