Hoegaarden Astronomy & Photography
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:
When testing out the new ASI183MMPro CMOS camera, I pictured the galaxy NGC3628. This is a well-known galaxy, sometime called the ‘Hamburger’ galaxy, part of the Leo triplet.
When processing the image, I noticed this very faint trace abit to the south of the galaxy. I used the Minor Planet Checker to verify any known asteroids in this area, and I found only one a bith south of the very little galaxy underneath NGC3628 that I used the coordinates from (using SIMBAD and ALADIN).
I doubt the magnitude of 21,2. When I compare to a star nearby that has the same weight on my picture as the asteroid, that star is identified by the GAIA catalogue as magnitude 19,5. So my estimate for the asteroide, since it’s a moving object would be around 20.
