Description

My rendition of this absolutely stunning region in the Orion-Eridanus border. This part of the sky is a particular challenge to capture from Brazil, since summer months (basically Nov.-Mar.) are the rainy season. This image was captured in a beautiful night in November 2021 from my dark rural site (proto-observatory) with mainly photographic equipment (full frame modded DSLR and 135mm camera lens on an unguided star tracker)

My goal was to capture not only the famous Witch Head, but also its busy surroundings, with bright nebulae, ther southernmost part of Barnard's Loop and very faint Ha and dust clouds that extend to the West (right). This image was a balancing act of nebulae vs stars, stretching for the extended faint features vs keeping detail and colour. Overall, I am more than pleased with the result, especially given the relatively simple equipment and short integration time of 2.5h.

Constructive criticism, comments and suggestions are more than welcome in the comments section!
