>>3004021Id suggest to get a good tracking mount, a 400mm lens like the 100-400 L II is an excellent refractor scope. Get at least an EQ3 or EQ5 mount or a good sturdy tripod and a Star Adventurer. The bigger one.
I felt the same when I got my first nebula shot, with M42 as well, pic related. On a crappy tripod with plastic parts that went jelly state under the 400mm lens.
