Hi, in 7 more nights my new 8" LightBridge should be arriving and along with it probably the worlds thickest and widest cloud belt so let me apologize for the miserable viewing.
On the upside three nights ago I managed to complete the Messier list in my 4.5" short tube reflector. Going to be interesting re-observing them and the H-400.

Congrats on polishing off the Messier list in a 4.5". Good going.
On the Herschel 400, going from memory of an article by Jay Reynolds Freeman who saw the whole 400 using a 55mm Vixen flourite refractor, I seem to remember the hardest to see was M76 (small planetary in Perseus) and NGC 6118 -- a low surface brightness galaxy in Serpens that is well placed for observing at this time of year.
Knock that last one over now while it's high in the sky and it'll be all downhill from there.
