The Eskimo Nebula in Gemini is a very small object. It’s comparable to Jupiter in apparent size. It’s also a lot dimmer then Jupiter so longer exposures are required. The ASI184mmPro has small pixels (smaller then the ASI290) and could, when seeing allows, bring out the finest details. The diameter of the planetary nebula is 48″ !!! Here is my attempt from last Monday:
This galaxy is the third member of the Leo triplet. During the last nights I could image this with the Esprit120mm and the ASI183MM Pro. This intermediate result is L-filter 6hr36m of data processed in APP and cropped. Best seen by clicking on the image!
And below is the equivalent image taken with the Nikon D750 DSLR. I had a lot of noise in this 3hrs picture (36x300s), I suspect something went wrong with the dithering. The tidal stream is just visible.Continue reading “An intermediate NGC3628”
