Hi all, Over the years, I have become more and more engrossed in astronomy. I am an amateur, enjoy studying the sky at night, have a special interest in astrophotography, like studying and analysing astronomical gear clocks and buildings, enjoy reading books and find it interesting to simulate certain subjects with especially spreadsheets (the "morsels"). I have collected all morsels and have published them on a dedicated website: astronomy-morsels.ch. Hopefully there is something useful for you, any tips are most welcome. One example is attached here. Best, Hans Object Data (Stars, Planets, Nebulae, ...) V1.0.xlsx

Yes, in Excel it looks good ...

Hi to those who are interested, Based on feedback received, I compiled a newer version, as attached. Still work in progress, but slowly stabilising ... Thanks! Hans Telescope Equations (V1.3.1).xlsx

Hi, thanks! Quite a lot of worksheets (9), added some screenshots. Best, Hans

I started listing my different telescopes, eyepieces and cameras, and wanted to create some guidance which combinations make sense. This ended up with a spreadsheet, summarising equations for combinations of telescope/eyepiece and telescope/camera. Also added data for Messier, planetary nebulae, Herschel 400 and Caldwell objects. See attachment. Any feedback welcomed! Best, Hans Telescope Equations (V1.2).xlsx
