Is this dust on the sensor? (image link)

I see the same spot no matter which lens I use so I'm pretty sure it's
not the lens.

This is a 20D.
It could be a bad pixel.

This is a little OT but, were you shooting for the condos or the Moon
in this shot?

LOL, it was condos. It was for a campaign flier for a referendum to stop
rezoning of land for condos. We won big time, and part of the reason was
we came up with very good campaign material. We also sued the developers
for their campaign tactics, and got one of the country's largest
developers to pay us $55,000 in legal fees that we spent fighting them.

Several dust spots. Use a blower bulb. May take several tries to get
them all.

Thanks. I tried a blower to no avail. Yesterday I brought it to the
local professional camera store where they do a lot of sensor cleaning,
and they said if they can't clean with a blower they'll do a wet
cleaning. They charge $45.

I've never done a wet cleaning and my camera is 3+ years old. I change
lenses frequently and often in blowing conditions.

I just hold the camera lens throat down (with the camera in sensor
cleaning mode, of course) and use a blower bulb with a long thin straw
quite close to the sensor.

Take out of focus f/22 shots of the wall to test. It usually takes 2 or
3 tries. Worse was about 7 tries. I've done this about once every 6
months (or less). (keep in mind that dust is on the opposite corner of
its location in the image).

This beats all hell out of spending $45 and not having my camera on hand.

I picked it up yesterday. Two days wasn't bad. I was talking to the
repair department person about what was done, and he said that most 20D
cameras require wet cleaning of the sensor. I just wasn't comfortable
doing a wet cleaning myself. They do a pre-test to check for the dust,
and a post-test to ensure that the sensor is clean.
