Welcome to Astronomy Morsels!

Explore a collection of astronomy-related spreadsheets (called "morsels").

Access a variety of handy morsels covering topics such as Spacetime (special relativity), Lagrange points (points of equilibrium), telescope equations, moon phases, planetary positions, including satellites and Jupiter's Great Red Spot, Messier/Nebula/Caldwell/Herschel and star observations, eclipse cycles and the Sarox-Inex Panorama, some sundial designs, etc. Also, models of gear trains of astronomical clocks are analysed (e.g., Antikythera). 

All morsels are standalone spreadsheets, without any macros, there are no security issues. All morsels have been carefully reviewed, and calculation results have been compared with other applications. But, Astronomy Morsels expresses no warranty: use is at your own risk.

Do not forget to vote!   please share your opinion about these morsels, at least if you download one or more morsels:  positive (4-5 stars) feedback implies more and better morsels ...!
