NGC 5128 - Centaurus A
Centaurus A is a galaxy that was discovered in 1826 bt a Scottish astronomer by the name of James Dunlop. Astronomers are still aguing about whether it is a lenticular or a giant elliptical galaxy. It's distance is roughly 12 million light-years away from us. It is a strong radio source as well as having very strong x-ray jets shooting out perpendicular to its galactic plane. It also has, at its center, a super-massive black hole that weighs in at about 55 million solar masses. This is my second image taken with Telescope.live.com remotely operated telescopes. It's a real joy to work with such good raw data.

 Messier 83 (NGC 5236) - The Southern Pinwheel Galaxy
This galaxy was discovered by Louis de Lacaille in 1752 and added to the Messier catalog in 1781. It is one of the closest and brightest galaxies in our night sky. It is classified as a Grand Design Spiral Galaxy and is very active in its star formation along the outer spirals.
This image was taken using the Telescope Live CHI-1 telescope in Chile.

M 82 is located up in the north in Ursa Major. It is classified as a Starburst Galaxy. Its core area is about 5 times the luminosity of the entire Milky Way Galaxy. The starbust designation is probably due to interaction with nearby
Messier 81 (M 81). It is part of our local group of galaxies.
This was one of the first images I did with Telescope Live in late 2019. The telescope, SPA-2, has a square chip in the camera, but the filters were round, giving its images a terrible vignetting problem. The sub frames weren't the best so I had to crop almost half of the image. This is my first attempt at blending Ha data with a standard RGB image. It still has some issues to resolve, which I'll fix as soon as I learn how to do a couple of other procedures in Photoshop,
