This is the California Nebula, aka NGC 1499, in Perseus near the star Menkib, or Xi Persei, at bottom. While this is primarly an emission nebula, there is dust in the periphery forming some faint reflection nebulosity. The main nebula emits strongly in not only the red H-Alpha wavelength but also the blue-green H-Beta wavelength, thus the pink or magenta colour. This is a stack of 12 x 6-minute exposures with the filter-modified Canon R (though no filter per se was used to take this image), at ISO 800, on the Askar APO120 refractor with its Reducer/Flattener for and 670mm focal length. Taken from home on October 19/20, 2023.
