Not accurately, without more information.
I assume you're in the Northern Hemisphere, but a nearby city or latitude would help.
We also need a date. If it was within the last week, Saturn was very near the horizon to the West at the time you noted -- much nearer the horizon than 85 degrees, which is practically straight up.
From the ESE to the SSE this time of year, in the Northern Hemisphere, the horizon is literally filled with faint fuzzies that could match your description. Many of these would have been at nearly the same apparent altitude as Saturn.
If you know any of this season's constellations and can more nearly identify the area of the sky for us, it would help.
Also, if by "large" you mean you couldn't cover it with your hand, you were most likely looking at the Sagittarius region of the Milky Way.
You can get a free monthly star chart at SkyMaps (be sure to download the correct hemisphere's chart) and it will help you find your way around the sky if you print it and take it outside with you.
