This is the bright reflection nebula complex that includes Messier 78 (the largest blue-white nebula) and NGC 2071 above it. They are set in a region of dark clouds of interstellar dust, and framed by the red-magenta arc of the emission nebula known as Barnard's Loop, aka Sharpless 2-276. The small reflection nebula at upper left on the edge of another dark cloud is van den Bergh 62. The large star cluster left of centre on the edge of the Loop is NGC 2112. This is a stack of 30 x 4-minute exposures through the Astro-Tech AT90CFT refractor with its 0.8x Reducer for f/4.8, and with the filter-modified Canon R camera at ISO 1600. No filter was employed here. Taken from home on November 13, 2023. Autoguided with the MGEN III guider on the AP Mach 1 mount. Applications of luminosity masks from Lumenzia, a PhotoKemi Nebula Filter action, and a Detail Extractor filter from the Nik Collection 6 Color EFX (the latter two applied to a starless layer created with RC-Astro Star XTerminator) brought out the faint background nebulosity and dark nebulas in this dusty region of sky.
