1. Western Veil Nebula C34 in Cygnus, from yesterday evening.
The Western Veil nebula is part of the Cygnus Loop gas cloud, around 2.4k light years away. The ring-shaped glowing gases are part of a supernova remnant that exploded around 10k to 20k years ago, at the time shining brighter than Venus and even visible during the day.
The image was acquired using Hydrogen alpha, Oxygen OIII and Sulphur SII 3nm Svbony narrowband filters.
It is then rendered in the CFHT (Canada France Hawaii Telescope) or HOS false color palette, where the H alpha line is mapped to red, the OIII line is mapped to green, and the SII line is mapped to blue.
SVbony SV550 122mm triplet APO on Skywatcher HEQ5 mount, Sony IMX571 26Mp cooled camera, optical polar alignment.
Total exposure time 134 mins.
No guiding, no wifi, no gps, no apps, no gadgets, manual focus with paper printed bahtinov mask, no darks, no flats, no bias, no added stars, no removed stars, no cropping, image minimally edited in Gimp.
This is one more recent image with the SV550 122, now under a full moon.
2. Dumbbell Nebula M27 in Vulpecula, from four nights ago.
M27 is - like the Helix nebula - another planetary nebula where the outer gas regions are illuminated by a bright central star, in this case a white dwarf remnant.

Optolong L-Enhance filter to reduce background glow. No garish coloring added.
Total exposure time 109 min, 15 sec subs.
No guiding, no wifi, no gps, no apps, no useless gadgets, manual focus with paper bahtinov mask, no darks, no flats, no bias, no added or removed stars, no cropping, minimal editing in Gimp.
