IC1805 / IC 1795

The Heart Nebula, also known as IC 1805, is an emission nebula located in the constellation Cassiopeia, approximately 7,500 light-years from Earth. It is often referred to as the Heart Nebula due to its shape, which vaguely resembles a heart when observed in certain images.IC 1805 is an active star-forming region where young massive stars are born from the surrounding gas and dust. These stars emit strong ultraviolet radiation that ionizes the surrounding gas, thereby producing the characteristic bright reddish glow of emission nebulae.The Heart Nebula is often associated with an open cluster of stars known as Melotte 15, which is located at its central part. This cluster is composed of relatively young stars that formed from the same cloud of gas and dust as the nebula itself.

This image was created over six nights, from January 11th to February 12th, 2024, accumulating a total of 37 hours of exposure time. The equipment used includes an ASI 1600mm Pro camera coupled with an Askar 400 telescope and its x0.7 reducer, which shortens the focal length to 280mm with an aperture of F/3.9. These five nights were spent in my garden in Le Cannet-des-Maures, southeastern France, under a Bortle 5 sky.
