Practice Data

Home

In learning to process images, I found it invaluable to practice on various datasets I found on the Cloudy Nights beginner imaging forum. One of the things I noticed, though, was that it was significantly harder in processing my own data. After I while, I realized that this was because the practice datasets were "very clean". There were very few problems with them whereas mine had significant gradients, lots of anomalies around the edges, bloated stars (before I got an apo), etc. I am therefore publishing some of my datasets as "less-than-pristine" examples you might see in real life.

PS: if you end up using the data, I would love to see your rendition. Post on Cloudy Nights if you are member.
