Thor’s Helmet Nebula

Thor’s Helmet Nebula NGC 2359 in the constellation Canis Major imaged with a Vixen R114 reflector at 900 mm focal length, an ASI 533MC cooled astronomy camera, a dual band H-alpha and O-III filter, with an ASI 174MM guide camera. This is a very faint target that requires a relatively large telescope with long focal length to frame properly and reveal details. This target is easy to locate using the three bright stars to the east of Sirius.
