NGC 1491
The Fossil Footprint Nebula.
Discovered in 1790 by William Herschel NGC 1491 can be found in the constellation of Perseus at a distance of approximately 11,000 light years from us.
Known as a HII region. This type of nebulae is caused by ultraviolet radiation from the hot young stars being born within ionizing the surrounding nebula, which cause it to glow in visible light allowing us to see it.
Boring techie bit:
Skywatcher Quattro 8" Newtonian Reflector steel tube with the f4 aplanatic coma corrector, Skywatcher EQ6 R pro mount, Altair 60mm guide scope, ZWO asi585mm guide camera, ZWO asi533mc pro cooled to -20c gain 101, Optolong L'enhance 2" filter, ZWO asiair plus.
85 light frames combined with calibration frames in DeepSkyStacker and then further processed using PixInsight, Graxpert & Affinity Photo.
