Image Description and Details: The kilohour project on Messier 31 stands as our most extensive effort yet, demonstrating the remarkable outcomes of collaborative work. By dedicating nearly 500 hours to Oiii observations, we've managed to bring out the arc's features with unprecedented clarity and define its structure accurately. This endeavor also allowed us to detect numerous extragalactic nebulae and resolve distinct stars within the galaxy. Opting for Sii exposures along with the usual Ha and Oiii was a beneficial choice, enhancing our findings.
In total we gathered 1056h of integration spread over LRGBHaOiiiSii
