The supernova remnant NGC 6992, NGC 6995 & IC 1340 (Eastern Veil, Network Nebula, Lacework Nebula, Caldwell 33) in the constellation Cygnus. The Eastern Veil is a cloud of heated and ionized gas and dust from a star 20 times more massive than the Sun which exploded about 8,000 years ago. It is roughly 2,100 to 2,400 light-years from Earth.
NGC 6992 was discovered by German-born British astronomer and composer William Herschel in 1783 /1784, NGC 6995 was discovered by his son John Frederick William Herschel in 1825 and IC 1340 by American astronomer Truman Henry Safford in 1866 (source: Wikipedia).
Exposure time: 6h 21min (127x3min) at gain 100 and -10°C, taken on July 5, 2025 and on August 30/31, 2025. Processing with Astro Pixel Processor (APP) and Photoshop. Darks, flats, and bias were used.
Equipment: Cooled ASI 2600MC Pro camera, TeleVue Paracorr Type II coma corrector, 8" f/4 "ONTC" Newtonian telescope riding on a ZWO AM5 Strain Wave Mount, ZWO OAG-L off axis system, ASI 174MM Mini guide camera, ASIAIR Plus.
NGC 6992 was also captured with a 16-inch dobsonian on an equatorial platform. The image can be seen here.
