This is a framing of the rich array of nebulas in central Auriga. The complex of star cluster Stock 8 and IC 417 is at upper left. The large nebula at lower centre is IC 410 with the star cluster NGC 1893 embedded in it. The large nebula at right is IC 405, aka the Flaming Star Nebula, with a mix of red emission and blue reflection nebulosity. The colourful asterism of stars between IC 410 and IC 405 is variously known as the Little Fish or the Flying Minnow., made of the stars 16, 17, 18 and 19 Aurigae. The field of view is just under 4° by 2.7°. This is a stack of 10 x 6-minute exposures with an Askar FRA500 astrograph (500mm focal length at f/5.5), and filter-modified Canon Ra camera at ISO 800. However, no filters were employed here. Nebulosity was brought out using successive curves with luminosity masks generated by Lumenzia, plus an application of the Nebula Filter action in PhotoKemi Startools Photoshop action set. All alignment and layering in Photoshop. Taken from home on January 27, 2022. Autoguided with the MGEN3 guider and dithered. No LENR or dark frame subtraction was employed on this mild winter night. Some light haze in some frames added the star glows.

The field of view is just under 4° by 2.7°. This is a stack of 10 x 6-minute exposures with an Askar FRA500 astrograph (500mm focal length at f/5.5), and stock Canon R6 camera at ISO 800. No filters were employed here, and the R6 performed very well for picking up the faint red nebulosity. Even so, nebulosity was brought out using successive curves with luminosity masks generated by Lumenzia, plus an application of the Nebula Filter action in PhotoKemi Startools Photoshop action set. All alignment and layering in Photoshop. Taken from home on January 26, 2022. Autoguided with the MGEN3 guider and dithered. LENR dark frame subtraction was employed to eliminate the edge amp glow the camera is prone to. Some light haze in some frames added the star glows.
This is a portrait of the main nebulosity in Orion in his Sword, including: the Orion Nebula itself (at centre), aka Messiers 42 and 43, and the Running Man Nebula above (aka NGC 1973-5-7). The bright blue star cluster NGC 1981 shines above the Running Man. The subtle reflection nebula NGC 1999 is below M42 but a bit lost amid the other faint and dusty nebulosity. The field of view is 4° by 2.7°. This is a stack of 11 x 6-minute exposures with an Askar FRA500 astrograph (500mm focal length at f/5.5), and stock Canon R6 camera at ISO 800. The camera was not modified and no filters were employed here. I did not take short exposures for the core of the bright Orion Nebula. Some light haze added star glows. Nebulosity is brought out in Photoshop using successive curves with luminosity masks generated by Lumenzia, and with applications of the Nebula Filter action from the PhotoKemi StarTools action set, and Enhance DSO from the Astronomy Tools action set. All alignment and layering was in Photoshop. Taken from home January 26, 2022. Autoguided and dithered with the MGEN3 guider, with LENR dark frame subtraction also applied to each frame in camera to eliminate the edge amp glow the R6 exhibits. It was about -5° C this night.
