Image Description and Details :

Located in the constellation Cassiopeia, this magnificent star forming region, surrounded by energized gas and dark dust lanes, is itself located alongside the larger Heart Nebula and is well known for its strong source of radio emissions.⁣

This image was created with data captured across 7 nights from October to November using a 8” Ritchey–Chrétien reflector telescope and a cooled, monochrome camera with both narrowband and broadband filters.⁣
⁣
The Hydrogen Alpha, Oxygen III and Sulphur II emission wavelengths are exceptionally strong in this region and I mapped the colour palette to try and make something truly unique! I belended in RGB stars for good measure. I hope you like it! ⁣

IC 1795 - The Fish Head nebula

IC 1795 is an area of gas and dust and also a star forming region in the northern constellation Cassiopeia.
IC 1795 is an extension of the larger Heart nebula or IC 1805.

The brightest part of the nebula has the designation NGC 896 in the New General Catalogue. It is classified separately because it was the first part of IC 1805 to be discovered.
