【實用工具app】Polar Scope Align Pro|最夯免費app-綠色工廠好玩App

Polar Scope Align will calculate the position of Polaris or σ Octantis in your Polar Scope reticle for your location (using your phone's GPS or manual coordinate entry), allowing a quick and accurate polar alignment. It is one of the few programs that are accurate in lower latitudes by correcting for atmospheric refraction. It will even allow you to measure and correct a centering error of the reticle - very useful for polar scopes that are not easy to adjust (e.g. iOptron ZEQ25). In the settings you can also select from a collection of reticles, one that matches your own - currently iOptron, Astro-Physics and Takahashi reticles are available. Feel free to contact the developer with any questions, feature requests, extra reticle requests etc.Feature list:-Accurate calculation of Polaris or Sigma Oct for any date and location, including effect of atmospheric refraction.-Use device time/date and GPS location, or manually enter your own.-Supports various reticles: iOptron, Astro-Physics RAPAS, various versions of Takahashi EM-10/11/500, NJP, P2-Z.-Longitude offset display (but not reticle) for Takahashi EM200/400.-Full app in red-color night mode.-Wizard to calculate your reticle centering offset and correct or compensate for it.-Zoomable reticle view.-Polar alignment when your scope is not in zero position (for mounts like iOptron ZEQ/CEM on which you can always access the polar scope).-Bubble level (using either gyro or accelerometer) and North heading.-Red/White/LED light.-Dimming slider.-Support for iPhone & iPad from iOS 6.There is also a free ad-supported version that does not allow manual entry of date/time/location and lacks some features like the zoomable reticle view, the bubble level and more.
