Thor's Helmet
This distinctive emission nebula in Canis Major is s tough target, faint and low in my sky. Imaged here in Narrowband, I have combined new data with last year's attempt. While this enhances the signal to background, I made an error in capture adding a lot of "walking noise" to the image, processed away to some degree.
