Atacama astrophotography dataset: NGC 4945 — Free Sample Dataset

NGC 4945: Free Atacama Sample Dataset

This free sample is designed to give you a first look at the quality of my astrophotography data captured under the dark, transparent skies of Atacama, in northern Chile.

Inside this sample pack you will find a small but useful set of files built for astrophotographers who want to test the data, compare their processing, and explore a real southern-sky target.

Included in this free sample:

• 1 stacked image file in fits and xisf format (87X600 seconds, Newton 200mm f5, ASI 2600MC camera, Bortle 1 sky)
• 1 finished reference image processed following my workflow with PixInsight and Photoshop
• 1 short data sheet with acquisition notes
• 1 quick-start processing note

This sample is meant to help you:

• evaluate the quality of the data
• experience my Atacama-based imaging material
• decide whether you would like to explore my premium Atacama datasets

If you enjoy working on this sample, you can find more complete deep-sky datasets in my store.

NOTE: Only for this free sample dataset, the resolution of the raw image has been reduced to 50%, but in the

ngc4945_technical_data.pdf file that you will download you will find an external link to get the full resolution data.

Usage note

This free sample is provided for personal learning and processing practice only. Redistribution or resale of the included files is not permitted.
