A real Celestron Origin session you can stack in OriginStack to see how it works, or to check your own setup against a known-good run.

What it is: the Whirlpool Galaxy (M51) and NGC 5195, 41 light frames of 25 s from one night (9 July 2026), with the flat, dark and bias the Origin saved. About 17 minutes of data, from a suburban backyard. The observer's location has been removed from the files.

To try it

  1. Download OriginStack-sample-whirlpool.zip below and unzip it.
  2. Install OriginStack if you have not yet.
  3. Open OriginStack, choose the unzipped sample_whirlpool folder as the light-frames folder, press Start.

A full run takes about a minute on an 8-core laptop. The galaxy is small in this wide field (a RASA at 335 mm); the result is a 41-frame stack, not a full night.

Free software, GPL v3. This release holds sample data only, not the app.
