Another nebula, which resembles a head of an animal is designated NGC 2174, sometimes called Monkey Head Nebula. After capturing the Horse Head Nebula in the constellation Orion, I waited for a few days for good weather and pointed my telescope again into the Orion, this time to its northern part. Monkey Head Nebula is an HII region, which is approximately 6400 light-years away from Earth. To find a monkey is not that difficult. There is a baboon’s head on the upper left side, which is looking into the constellation Taurus.
The best way to capture this nebula is by using narrowband filters. For this purpose, I ordered a new monochrome camera ZWO 2600MM with a 2″ filter wheel. The filters are equally important as a camera, so I decided on Antlia 3 nm. As a first light, I must say that this combination works really well. I made in total 90 exposures, 5 minutes each, which means over 7 hours of integration time.
