here are a few pics I have taken with my zwo174mc .I am learning and teaching myself , but am pleased with some of my results so far . I use an advanced vx mount and am fairly meticulous about alignment . I use a 6000 series meade ed apo triplet refractor . No auto guiding yet so my dso imaging is usaly about 100 second subs , but with good alignments I think this could go up to 3 minutes without auto guiding
