Cygnus A (3C 405)
The famous 15th (visual magnitude 15.1) magnitude elliptical galaxy. One of the strongest radio sources in the sky. Wolfgang Steinicke has reported seeing the galaxy using a 14" telescope @ 450x [1].

I'm not a big fan of stellar planetaries and I am especially not a fan of spotting one from a dense star fields of a globular cluster. Still, worth a try as I've never tried to seriously see Pease 1.
PGC 69457
Einstein's Cross. Copyright ESA |
Huchra's lens. Another 15th magnitude galaxy at a somewhat low altitude in Pegasus. Seeing the actual Einstein Cross won't be happening with the 10 inch telescope but just seeing the lensing galaxy is still something.
Gyulbudaghian's Nebula (GM 1-29)
Variable nebula in Cepheus. Usually unfortunately faint.
Mayall "C" (C39) & Star B 342
Brightest globular cluster and brightest single star in Triangulum galaxy. With the extra 2 inches in aperture, seeing it will probably be fairly doable.
NGC 1554-5
A classic. Hind's Variable nebula. Time for a new view.
Several Messier objects...
There are a bunch of Messiers I still do not have a proper sketch of. I will try to do a few of them in the upcoming season.
