A New Toy--the Dwarf D3 telescope

Another toy arrived yesterday--the DWARFLAB D3--a tiny scope with a 35 mm 6-element apochromatic main imaging lens and small wideangle lens for Milky Way imaging (among other things). Of course, the clouds rolled in, but I was able to do some imaging, most of it through the clouds themselves. My first light object was the Moon, just to check focusing and function. I'll post that image later. The second was M42 because it is relatively bright and easy to capture. Setting up the scope in EQ mode was a simple, semi-automated process. The imaging chip in the scope, a Sony IMX678 Starvis 2 does an excellent job of capturing faint images with relatively low noise. I captured 40 minutes of M42 before heavy cloud came in, using the built-in narrowband filters in the scope. I drizzle processed the image stack in Siril as the scope significantly undersamples (making the native 4K frame 8K). I then heavily cropped the image horizontally, and the result (below) is quite pleasing. The original frame was much wider, and promises to offer great capabilites to image larger DSOs (like the Heart Nebula, for example). The scope is so small, you could almost clip it to your belt, so its a definite travel scope for me.
