ASTRO: Four open clusters (NGC 663, 654, IC166, Berkeley 6)
I recently put the Explore Scientific 0.7 3" reducer on my ES 127 FCD100 APO and was pleased to see that they both work well together.
As the sky was not good enough for faint stuff I imaged a field that contains four open clusters. IC 166 (upper left) is my favourite with all it's faint yellow stars.
Taken from Berlin with an ASI1600MC cool camera, 110x2 minutes.
