Vinter 2023

Januari - april 2023

I slutet av 2022 köpte jag ännu ett teleskop med lång brännvidd, så det blev mycket djuprymdsfoton under början av 2023. Sedan hade vi ju också flera roliga besök av våra numera fem barnbarn.

M51 Whirlpool galaxy
M51 Whirlpool galaxy
The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be between 15 and 35 million light-years. The galaxy and its companion, NGC 5195,are easily observed by amateur astronomers, and the two galaxies may be seen with binoculars. A black hole, surrounded by a ring of dust, is thought to exist at the heart of the spiral. The dust ring stands almost perpendicular to the relatively flat spiral nebula. A secondary ring crosses the primary ring on a different axis, a phenomenon that is contrary to expectations. A pair of ionization cones extend from the axis of the main dust ring. Photographed with RC8" reflector telescope and ASI 2600MC color camera in Stuvsta, February 2023. 41*3min exposure with IDAS LPS D2 filter.
