I had just finished capturing some images of the Moon with the EdgeHD 9.25" and Canon 6D2 (it fits the Moon in frame with little vertical room to spare).  The seeing was much, much better than the 'predicted' poor seeing.  I'd checked the 'stars' to see if it was going to be worth the effort to drag everything out and setup.

 

I think I got some of the 'gravel' from the crater in the imaging train, LOL.  Seeing the entire frame of the sensor illuminated brought out all the specs of dirt on the sensor and 'dust' donuts further up in the imaging train.

This is a very nice image of Copernicus. And the "gravel" in the crater is not an artifact, it is really there. You can see it in this image I acquired.

I was making a bit of a joke about the 'gravel' being the cause of the dirty sensor, not necessarily that I thought it was artifacts.  wink.gif  The dirt on the sensor isn't visible in the final image, fortunately.

Stacking does tend to hide at least partially the dust bunnies.

I use compressed air to clean the surface of the sensor every imaging session (without getting the can so close that it will condense).  That has seemed enough to keep away any dust artifacts for the several years I have imaged.
