The Dark Site Finder website uses a Google Maps interface overlaid with color coded light pollution data. White, red and orange tones indicate extremely light polluted areas that are poor for skywatching. Yellow means moderate light pollution, and green through black indicate the darkest skies. You can pan and zoom in and out on the map to find darker skies within a reasonable driving distance or check the skies at your upcoming vacation spot. A Planet Skywatching Guide for 2. When, Where How to See The PlanetsThe Dark Site Finder website overlays worldwide light pollution data onto Google Maps.

Using your phone to set up your telescope Telescopes with equatorial mounts, and most motorized Go. To and tracking systems, need to be set up level and aligned with the Earths polar axis. The better they are aligned, the more accurate the tracking and Go. Tos will be. Long exposure astrophotographs will be sharper, too. Heres how your phone can help. At night, the polestar Polaris, or the North Star can be used for alignment. But if you are setting up a tracking telescope to observe the sun or a nighttime scope before its dark enough to see Polaris or if you are in the Southern Hemisphere, where there is no polestar to align on it helps to have a compass app handy. There are plenty of free ones. You need to set up based on true north, not magnetic north. The better compass apps will include whats called a declination correction for this. To level the telescope tripod, install a bubble level app, and simply rest your phone on the eyepiece tray or another part of the mount. Find an app that levels in two directions simultaneously, such as a circular bubble level, and that buzzes when levelness is achieved so that you can adjust the tripod legs without needing to see the phones display. The polar or right ascension axis of equatorial mounts need to be tilted at the angle equal to your latitude on Earth. Pick a bubble level app such as Bubble for Android or Bubble Level for i. Phone and i. Pad that has a digital readout of the tilt. Then, use it to check the angle of the telescopes tube, or the polar axis directly. Crack Kaspersky 6.0 there. For mounts that have counterweight shafts, you can hold the phone against it. The shaft should be tilted at 9. Remember that your devices compass and gyroscope need to be calibrated properly. Bubble level apps have options to zero the reading when your phone is resting on a horizontal surface. Compass apps will have instructions to sweep your phone in a pattern that corrects the magnetic readings. Be sure to avoid standing near metal objects, such as your car, when doing this. Another good option is to check your phones tilt and compass readings on a telescope that you know is already aligned, using the polestar. Designed for hiking and other activities outdoors, the Polaris GPS Navigation App is also handy for astronomers for setting up and aligning a telescope. The app displays the position and time data from your devices GPS receiver, as well as the compass bearing. Credit Polaris GPS Navigation App. Finally, computerized telescope mounts also need to know the correct time and observing location so that they can calculate where the stars are. Your phones GPS sensor measures these, but there isnt always an easy way to access the values. I find that a good hiking or navigating app, such as DS Softwares free Polaris GPS Navigation for Android, offers everything youll need, including a compass. June Full Moon 2.

Steve B, CaliforniaJust a quick comment. I dont know how Id plan my astrophotography without this tool  Especially the artificial horizon feature which saves me a lot of time. David L, Queensland AustraliaBy far the cleanest and most trouble free piece of Astronomy related software I own Joe D, TexasFrom my perspective, DSP is a comprehensive planning and logging system which is worth anyones time and money to employ in their observing life.
