Got 3,5 hours with Main and the UnderDog. Seeing not so good but got enough data to evaluate the concept of using a small telescope in parallell to main to get aditional data of Ha and OIII. One Shot Color in five channels! Results from Main: RC8", Sony a7, L-Pro and Underdog: Evo Guide 50ED, ASI462mc and L-eNhance is given as version 2 and 3.

M33 is a spiral galaxy in the constellation Triangulum, also known as the Triangulum Galaxy or NGC 598¹. It is one of the nearest galaxies to the Milky Way, lying at a distance of about 2.73 million light years¹. It is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way¹.

M33 has a diameter of about 61,000 light years and contains about 40 billion stars¹. It has a high rate of star formation and hosts many regions of interstellar gas and dust, such as the giant H II region NGC 604, which is one of the largest and brightest nebulae in the Local Group¹. It also has several satellite galaxies, such as Pisces A and Pisces B, which are dwarf galaxies that were recently discovered by the Hubble Space Telescope¹.

M33 was discovered by Charles Messier in 1764, who catalogued it as object number 33 in his list of nebulae and star clusters¹. It was later observed by William Herschel, John Herschel, and Edward Barnard, among others¹. It has been imaged by various telescopes, such as the Hubble Space Telescope, the Spitzer Space Telescope, and the Chandra X-ray Observatory, which revealed many details of its structure and dynamics¹.

M33 has an apparent magnitude of 5.72 and an apparent size of 70.8 by 41.7 arc minutes¹. It can be seen with the naked eye under exceptionally good viewing conditions with no light pollution, or with binoculars or a small telescope under any conditions¹. It appears as a bright patch of light near the star Beta Trianguli in Triangulum¹. It is best seen from the northern hemisphere during winter months¹.
