Description

The region of Sagittarius surrounding M8 and M20 is densely packed with star clusters and both light and dark nebulae. Apart from the prominent Trifid (M20) and Lagoon (M8) objects, other features of interest include the winding Chinese Dragon nebula, the dark nebula B91, Webb's Cross Cluster of young blue stars and the diminutive globular cluster NGC6544.

This image was my first attempt at a mosaic using a DSLR camera. Changing sky brightness during the course of the night and some distortion near the corners of the field presented some challenges in smoothly stitching the panels together. Given the relatively short exposure time, I was surprised at the amount of faint H-alpha detail that was pulled out using an unmodded Nikon D5600.
