The Rosette Nebula (aka NGC 2237) in Monoceros, an emission nebula and site of star formation in the Orion Arm of the Milky Way. The star cluster at the centre of the nebula is NGC 2244. This is a stack of 8 x 8-minute exposures at ISO 800 with the Canon EOS Ra camera blended with a stack of 8 x 8-minute exposures at ISO 3200 through an Optolong L-Enhance dual-band nebula filter to bring out the red nebulosity. All were through the Sharpstar HNT 150mm Newtonian Astrograph from home on February 19, 2020.
The Rosette Nebula in Monoceros, aka NGC 2237-46, plus the central star cluster NGC 2244, taken in deep red light only through a narrowband Hydrogen-Alpha filter and rendered in monochrome. Taken in bright moonlight but the narrowband filter makes such imaging possible in bright skies as most of the light is rejected by the filter. This is a stack of 8 x 8-minute exposures through the Canon EOS Ra camera at ISO 1600 and with the SharpStar HNT150mm astrographic reflector at f/2.8 and with a clip-in 12nm Ha filter from Astronomik. I shot the images Feb 2, 2020 with a bright quarter Moon in the sky making the night unsuitable for normal full-colour imaging.

This version is processed with the addition of a Nik Collection Silver EFX filter to add a selenium look to the toning and a picture frame, for a old-fashioned look. Just a test for fun!
