Per my previous post, my Celestron CGEM equatorial mount had been out-of-action for the last few mounts due to a dead motherboard. I managed to replace it recently and this is the result of a test image using the new board. I'd say it works fine!
Below is an image of the nebula in Hubble HSO palette. In this HSO palette rendering of the Monkey Head Nebula (NGC 2174), the dominant color story is a warm golden-amber wrapping the exterior shell, representing sulphur-II emissions from the cooler, denser ionized gas at the nebula's outer boundary. That golden envelope gives way inward to the striking blue-white core, where hydrogen-alpha and oxygen-III combine to create the luminous, cloud-like interior — the OIII in particular driving that icy blue glow around the embedded star cluster. The dark intrusions you can see cutting into the rim are dust lanes and molecular cloud structures silhouetted against the emission.
The Monkey Head Nebula (NGC 2174) is a vibrant emission nebula and active star-forming region located ~6,400 light-years away in the constellation Orion. Associated with the open cluster NGC 2175, it features glowing hydrogen gas sculpted into complex, chaotic shapes by stellar winds from young, massive stars.
