Earth Centered Universe Planetarium Software

Both Colin and I were long-time friends of Dave Lane, who passed away last year. He was the author of a very nice planetarium program called Earth Centered Universe.

As a tribute to Dave, I have taken over ECU and am now making it available free of charge. It is available from https://www.nova-astro.com (Diffraction Limited is now hosting the domain. It's running a pared-back version of Dave's site; I plan to update it when I have some time.)

If you enjoy ECU, please consider making a donation to StarFinder - The David Lane Astronomy Outreach Program established by Dave and his wife Michelle Lane. https://www.smu.ca/giving/david-lane
