Cloudy at sunset, but set up the 10” LX90 on basis of weather report of clearing later.  Clouds finally parted about 11:30 pm – still warm and humid, so I used the DewZapper strip on the front of the telescope.  Aligned the scope using the 25mm eyepiece and slewed to Albireo – as usual, great sight.  Inserted the new 12mm T4 Nagler eyepiece – about doubled the magnification, and what a sight.  Brilliant colors of this binary.  Went to M-13 – beautiful!  This cluster just about filled the fov and the detail was amazing.  Viewed several doubles and one carbon star:

Aquila

5 Aquilae (SAO-142606) Mag 5.5/7.5, 13.0” separation – easy split

15 Aquilae (SAO-142996 RA19:04.9; DEC-04.01) Mag 5.5/7.0, 38.4” separation – very easy split.

STF-2449 (SAO-124265 RA19:06.4; DEC+07.09) Mag 7.0/8.0, 8.0” separation – close pair, but easily split at this magnification

V Aquilae (SAO-142985) Mag 5.5 carbon star – very nice, brilliant reddish color.

Sagitta

SAO-105104 Mag 6.5/8.5, 28.4” separation – primary is a carbon star - nice pair.

Lyra

Epsilon Lyra – viewed previously, but nicely split with new eyepiece.

“Other double-double” (Struve 2470/2474) – barely fit in the fov with new eyepiece, but easy split of both doubles

Cygnus

52 Cygni (SAO-70467) Mag 4.0/9.0, 6.6” separation – the secondary star barely visible, but discernable with averted vision, very close to brighter primary.  52 Cygni is located within the west veil nebula, NGC-6960, but couldn't see the nebula in our moderately light polluted skies.

Sounds like a fun night.  That's a very nice picture of SAO 105104, you captured the colors very well.
