Greg you are doing really well. I haven't heard of anyone seeing the Cone.
You should be able to see M1. Try NGC 346 the bright neb in the SMC.
It is between NGC 330 and NGC 371 in the north of the SMC.
Also try NGC 2174 near M35, it is visible in my 50mm finder.
Others to try are NGC 2359 and NGC 2467 near M93.
A UHC filter is great for nebulae.
