Description

A wide field centered on Sagitta. M27, M71 and the Coathanger are included; also Barnard's E. Focal length 37.1 mm, aperture f:4.9.
The original version was a quick-and-dirty job preprocessed with DeepSkyStacker (on Wine on Linux) with darks but no cosmetic correction, flats or bias, and postprocessed in Siril 0.9.12 with final curve tweaking in GIMP 2.10.
The current version, entirely made with SiriLic and Siril 0.99.7, has cosmetic correction and better color and is livelier. It still lacks flats, though.
