Chapter 6.4 Processing a dual-band multisession image
The image dataset was captured with a full-frame Sigma FP camera modified with an Astronomik filter and paired with an Optolong L-Extreme 7 nm dual-band filter.

Chapter 6 of the book is devoted to practical case studies for which we provide image datasets that will allow you to apply the processing techniques presented.
These image datasets are supplied as ZIP files that are relatively large (2 to 8 GB). To avoid the inevitable congestion in December, when hundreds of readers will want to download them, we suggest that you download them only when needed, that is, after reading Chapters 1 to 5 of the book.
If you encounter any problems, please feel free to contact us.
