DrakeEQ vs AstroFinder

Are we alone? We created DrakeEQ to provide a visually elegant answer to the extraterrestrial question, using the intellectually elegant Drake Equation. We coupled this fun calculator with beautiful, 3D galaxies in motion! To help us celebrate 15 years since the first release in 2009, DrakeEQ 7.0.0 now features our Galaxene Galaxy Engine! Use this fun simulator to graphically quantify the number of advanced extraterrestrial civilizations in our Milky Way Galaxy. Travel the Universe and explore infinitely variable galaxies! Just pinch anywhere and tap the targeting indicator. Perform thought experiments with this unique visual tool; it’s both educational and entertaining. Learn about the famous Drake Equation through direct manipulation of its 7 parameters with DrakeEQ. The Drake Equation states that: N = the number of civilizations in our galaxy with which communication might be possible where: R* = the average rate of star formation in our galaxy fp = the fraction of those stars that have planets ne = the average number of planets that can potentially support life per star that has planets fℓ = the fraction of the above that actually go on to develop life at some point fi = the fraction of the above that actually go on to develop intelligent life fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space L = the length of time such civilizations release detectable signals into space.

**AstroFinder turns your iPhone into a plate-solving push-to finder for any telescope — no motors, no alignment stars, no setting circles.** Clamp your phone beside the scope. AstroFinder takes a short exposure of the real sky, identifies the star pattern the way a research plate-solver does, and repeats about once a second — so you always know exactly where you're pointed. A red-on-black star chart shows your aim live, and a simple arrow guides you onto whatever you want to see. **Find anything** • Planets, Sun and Moon — sorted by what's up right now • Deep sky by catalog number — Messier, NGC, IC, and more, on a keyboard-free keypad • Named stars and showpiece double stars • "Best this month" — well-placed showpieces for your location, tonight, nearest to where you're already aimed **Built for the eyepiece** • Fully night-vision friendly: red on black, dimmable below the phone's own minimum • Alt-azimuth mode for Dobsonians (no field rotation) or equatorial mode for tracking mounts • Tap any object on the chart for details, then push-to it • Optional constellation lines, labels, and progressive zoom as you close in • Works in portrait or landscape, at any mounting angle **How it works** AstroFinder mounts alongside your telescope and syncs to your eyepiece in seconds. From then on, the chart and all guidance are aligned to your scope's actual aim. Everything runs on-device — no internet needed under the stars. A one-month free trial gives you a full new-moon cycle to try it. Subscription then renews yearly; cancel anytime.
