You also managed to catch the head of Taurus the Bull at upper right--the V shaped asterism is the Hyades star cluster, which forms the bull's head. The red star there is Aldebaran, the Eye of the Bull. If you extend the two legs of the V toward the upper left the two bright stars you see are the tips of the bull's horns. The planet Mars is presently hanging out between the tips of the horns; I don't see it in the image.

Betelgeuse is the bright reddish star at Orion's top left (his right shoulder as he's facing us).

Look up the Boogeyman Nebula. Here, I'll find it for you:

Sounds like you're using a grinding wheel as a cutoff wheel.

The ash, the washer fluid wasn't a factor. The ash was actually very gritty, sharp edged particles like sandpaper or worse.

I was living in the Colorado high country at the time of the eruption. I got up the next morning to drive to work. My windshield was dirty, I turned on the wipers and squirted washer fluid to clean it. I ruined my windshield instantly.

This is why aircraft carriers turn into the wind when launching or landing aircraft.

You're going to have to dress the corners of the door and/or the frame with an angle grinder. Relieve them a bit so they don't touch.

ETA: or the flats, as the case may be. I've never seen a door like that.

If you draw a line from the tip of the Teapot's spout to the bowl of the Pipe, the center of the galaxy is in the middle.

It's dark nebulosity along the plane of the Milky Way galaxy, and it's many trillions of miles (many light years) away, as are the stars. See the dark cloud shaped like a pipe, just right of the Milky Way, above center? It's called the Pipe Nebula. The center of the galaxy is a little to the lower left of the bowl of the Pipe, behind the one band of dark nebulosity. The Teapot of Sagittarius is on the left side of the Milky Way, opposite the Pipe. The stem of the Pipe points right at Scorpius the Scorpion. The Pipe also forms the back leg of the Dark Horse, which extends to the upper right. You can make out its crooked front leg, neck and head.

There is a ton going on in the pic, I won't bore you with it all.

There is a dark pipe-shaped cloud to lower right of center, it's called, well, the Pipe Nebula. It also forms the back leg of what's called the Dark Horse--its body, bent front leg and head extend to the upper right. See it? Also, the center of the Milky Way galaxy lies just to the lower left of the bowl of the Pipe, in the middle of the dark cloud.

There are actually three galaxies visible in the image--Messier 31 is the big one. The round fuzzy to the left is M32, the oval fuzzy to the right is M110. Both are satellite galaxies of M31, like the Magellanic clouds are to our Milky Way.
