I think the OP was actually asking about DSOs that we just recently observed, and we had not observed before.
Weather last cooperated last Saturday, but only had 1 hour between the end of astronomical twilight and moonrise. The plan was to use a 135mm telephoto lens to pick up a few targets too large for my telescopes. Six observations with one nice catch. From my observing log:
Sh 2-134 BN Cepheus 4 Oct 27, 2018, NV 135 Telephoto, Home: SkySafari shows one object depicted I definitely see two small nebulous condensations in a nebulous glow at that location. Needs more research (another SkySafari chart error?) and observation.
Sh 2-178 BN Cepheus 1 Oct 27, 2018, NV 135 Telephoto, Home: Next to Polaris! Extremely large and faint, averted vision required.
Sh 2-91 BN Cygnus 2 Oct 27, 2018, NV 135 Telephoto, Home: Large in faint without a lot of structure. Just a patch.
Sh 2-94 BN Cygnus 2 Oct 27, 2018, NV 135 Telephoto, Home: Large in faint.
Sh 2-118 BN Cygnus 3 Oct 27, 2018, NV 135 Telephoto, Home:
Sh 2-124 BN Cygnus 2 Oct 27, 2018, NV 135 Telephoto, Home:
The most "interesting" one was the faintest - Sh 2-178. It extends from northern Cepheus and almost seems to touch Polaris! I had no idea it was there until I saw it plotted from my list - never thought to look for a nebula there. It was extremely faint, even with the NV eyepiece and 7nm H-alpha filter. I had to rock the mirror back and forth to move over the edges to confirm it.
