An app for quick and useful camera calculations - Forums

Hello everyone,
I would like to share a calculator I made for my personal use, but it might come in handy for many of you out there—especially if you’re out in the field and need an app that doesn’t require an internet connection.

It helps you figure out some important numbers like pixel scale, sensor width/height/diagonal in mm, sky field, and ideal imaging conditions (that’s it for now).

You can download it here:
https://github.com/ecliptico/astro/releases/download/v1.1.0/Astrocalc1_1.exe

Please let me know if you’d like me to add more features.

Cheers,
Guy

Really handy tool, especially for offline use in the field! I just tried it out and love how straightforward it is. The pixel scale and FOV features are super useful.

Hey everyone! I would like to share the new release of the app (v1.3) — now featuring 17 tabs packed with essential calculations for efficient and accurate astrophotography planning.

While this update adds a bit more complexity, I truly believe these tools cover calculations every astrophotographer will need at some point.

If you spot any bugs or have ideas for new features, I’d love to hear your feedback for the next revision.
