OK, so it's Lemmon, not Lemon ...
but anyway .. it isn't moving THAT fast that you can't use sidereal tracking and 30-60 second exposures. So regard it as a normal DSO object and go for it. I took a single 3200 ISO jpeg at 20 secs to get mine. Others I beleive have used planetary methods, avi and stack to get theirs.
Good luck
