Sky appeared clear
with much twinkling. Faintest star observed through telescope mag 11.7
New objects for me Old objects being observed for reference value.
Equipment – XT8 Orion (8" F/6 Dobsonian)
Charts – Starry Night Pro (SNP) software on laptop
Since I got the O-III and UHC filters I would HIGHLY recommend them for anyone observing in the light polluted skies of the city. If I had to choose one over the other I would definitely choose the O-III for city viewing however dark skies may be another story. Mars – Seeing prevented observing any detail

Threshold check with TYC5685-3140-1 Mag 11.31 barely visible in 21mm
Clear Skies,
EP's – 21mm 85* fov Siebert, 32mm Plossel with UHC and 25mm Plossel with O-III
The 21mm provided a better view without filter than the Plossels but since the Plossels were available, threaded for filters, they came in very handy providing a good view with the filters and allowing me to switch back and forth very quickly.
* Almost no nebulosity using 21mm EP without filter
* 2 Clouds visible with separation using 32mm with UHC
* 2 Clouds and faint 3rd cloud using 25mm with O-III
* Faint fuzzy with no detail
* No Nebulosity with any EP
* No Nebulosity with any EP
At first I thought this was a double since they were about 10" apart but SNP labels them as singles possibly because they are actually 213 ly apart.
* Slight nebulosity with 25mm/O-III and 32mm/UHC
* Not very bright with light pollution
* Not very bright with light pollution
* Faint almost swan with 21mm no filter
* Definite swan with O-III and UHC
* Very faint nebula with O-III and UHC
