It is estimated that there are between 200 billion and 2 trillion galaxies in the universe. Each galaxy may contain several hundreds of thousands of stars. It is for example estimated that our galaxy, the Milky Way has over 100 billion stars. Galaxies are classified either as ellipitcal, spiral or irregular. Galaxies are made of stars, stellar remnants, interstellar gas, dust and dark matter.
Below you will find my best images of 2020 and 2021. All were taken either with my Skywatcher Evostar ED-80 or the Skywatcher ED-120. I used the Nikon D750. For these shots of galaxies, I used the Optolong L-pro, is a multi-bandpass filter which selectively suppresses light pollution.
