"The image shows M33, the Triangulum Galaxy from a new perspective. Due to tidal interaction with M31, there is very prominent star-forming activity in M33, which results in a spectacular structure of emission nebulae. During processing, a separate SHO picture was created with a strong SII/H-alpha presence, the glowing red structures in the picture, and blended with a high-resolution LRGB processing of the continuum data, representing the ‘background’ light."

Taken with a custom-built 250/1000 Newtonian astrograph and Lacerta 300/1200 Photo Newtonian telescope, Antlia V-Pro LRGB and 3 nm H-alpha, OIII and SII filters, Astronomik LRGB and 6 nm H-alpha, OIII and SII filters, Sky-Watcher EQ8-R Pro mount, ZWO ASI2600MM Pro and ASI294MM Pro cameras,1,000 and 1,200 mm f/4, 8.4-hour L exposures, 6.8-hour R exposures, 6.7-hour G exposures and 6.3-hour B exposures, 39.3-hour H-alpha exposures, 15.3-hour OIII exposures, 28.3-hour SII exposures.
