Taken with my little 114mm frankenstein newt made of spare parts. I ran 30 second unguided subs since I can't get the guiding to work right, but it seems to have yielding some decent results. I was pleased the star shape was pretty consistent across the field, especially for an F4 primary that started life as an Orion Starblast (not a bad scope as these results show).
