Lunar Calculator

Plan your lunar observing: zoom in, identify craters, search librations, alt/az, for photo opportunities

Lunar Calculator

LC23 install package (13MB) change .pro to .exe before running. 

Freeware/shareware. Registered users receive a security key to access full functionality. Click on the title above to begin download. change .pro to .exe, then click on the EXE to self-extract, and it will auto-install. Then run lunv2.exe. No need to restart the machine. For Vista/Windows7, you will have to run this in Win95 mode. For the time being, this version remains frozen. I hope to return to programming before the end of the decade.

This v2 release has SEAMLESS Clementine display. Check out the screenshots for more details.

Payment can be in US cheque or money order. Sorry, no credit cards or paypal.
Even if you already have the Clementine CD, there is no price reduction because the delivery CD contains over 90 Meg of special image files.

What Clementine/USGS imagery is included?

  • Registered users receive the NASA Vol 15 Clementine LDIM CD at no extra cost.
  • Registered users also get the USGS texture map at 0.5 km (0.3 mile) per pixel
  • In the free Lite mode, Lunar Calculator comes with Clementine imagery and USGS texure map and blends at 5 km (3 mi) per pixel, and has no expiry date . However, it is limited to a 35 day interval on each side of the day you run the program. In other words, if today is June 10, 2013, then the Lite version will work for days between May 5, 2013 to July 15, 2013. Also it will not plot the smallest features (less than 3km/1.8mi).
