This image provides a detailed view of Sunspot 1084 on July 3, 2010. The author is French astrophotographer Thierry Barbier. He uses a DMK 41AU02.AS astronomy camera.


His e-mail is translated as below:

A movie of 300 images at the focus of an achromatic refractor SW 120×1000, ERF filter 90mm f/10, PST and 2x Barlow.

Processing in Registax for typesetting, Iris thresholds, and wavelet colorization.

The image has been reduced to keep only the interesting parts. Note the fine filaments in the lower left.

Many thanks to Thierry!
