Description

Even if is one of the closest planetary nebulae to us it was by far the faintest object I tried so far. At 300 sec at F4.7 you can barely see something in Ha and Sii and almost nothing in Oiii. It's a very large nebula so it almost filled the FOV in the 341mm FL. The processing was a nightmare even if I got about 18h of data.
