I am the owner of Allan's regret, and I'm glad he sold it
I won't be making the same mistake.
I really love it, it seems to laugh at light pollution, and I don't bother with dark frames any more, and it is as sensitive as all get-out.
I am experimenting now with a big-arse mono quantix, but won't be parting with the QHY8, it really is the bees knees as they say.
