I’ve been giving away free Astronomy Logs, created in Filemaker, and runnable on MacOS, Windows and iOS, since 1998. Unfortunately, the technology changes, and I don’t. In the past four years, my site has been hacked a couple of times, so this is probably the last time I’ll restore and refresh it. Please bear with me while I restore the pages and apps. By 1/1/2019, all should be back in order.
TUMOL – The Ultimate Messier Object Log
TSOL – The Simple Observing Log
OOLOG – Overlooked Object Log
