Steve, Rodney, Stephane, Michael, David, thank you very much for kind words!
I was initially surprised that there are so few photos of this nebula, although it is small, but not nearly as tiny like many "Hubble-only" planetary nebulae. In fact, I was also secretly hoping that it might have a large but very weak halo (something like hydrogen in M57, or mixed in M27 or super-weak mixed as around IC 5148). So I decided to give my best as much as possible in it's visibility season from my balcony. Unfortunately, this hypothesis has not been confirmed, at least on the level of sensitivity available with my LP conditions and equipment. But it turned out well enough anyway
