I have wanted to image this object for years ever since I saw it in a picture. However, being a planetary nebula I always thought it would be far too small on the Hyperstar III rig to be interesting. As it turns out – it is quite a bit bigger than I was expecting. The blue sphere in the centre of this image is Abell 39 – a planetary nebula in the constellation Hercules – and it is the object I find the most fascinating of those known out there in deep-space 🙂
Captured with the Hyperstar III on the C11, 20 subs at 5-minutes per sub, processed by yours truly.
