This may come across as a bit controversial but I personally believe that the intent is 9/10ths of the law. A few weeks ago (over a newish moon) I took some of my friends up to my dark site with my imaging setup (130mm refractor and QHY9) and an Orion 12" Dob. Got there at dusk, I set up my imaging scope while the others started a small camp fire to boil some water and make some tea. Sunset was like near 9pm btw.
Come about 11pm my imaging scope is all ready to go, haven't even touched the dob which I only brought two weeks earlier and didn't have any way of really collimating it. So I figured I would start by giving my friends a tour using my imaging scope; processing was pushing the Digital Development button in MaxIM DL, so less than 1s of processing.
With there having been a new supernova in NGC 5128 that we would not be able to see visually (due to sub par collimation on the dob) I took a 30s exposure so show them the most recent supernova.
After that I went to M42 to show the core with a 1s exposure which bought out the E&F stars.
While showing some of the inner parts of M42 on my laptop (and a 10 hour full colour version on my iPhone to compare) I had the camera taking a 60s Ha of the Horsehead Nebula, something else that we wouldn't be able to see very well with the dob.
Then it was onto the Rosette for a 60s Ha and explained what it was that we were looking at.
From there I moved over to the Antennae Galaxies with a 5s and then 60s exposure to show the vast difference that it makes. Then I started a 1200s exposure so we could make another cup of tea and I put the dob together so we could do some observing.
Now to some, what I did would mostly be considered imaging, especially with a 1200s guided sub. The point of that was more than anything to go deep and show the tidal tails of the two interacting galaxies. Let's face it, that is pretty awesome. 1200s was good for me because I knew in 20 minutes I could get my 12" dob together and doing a reasonable GoTo job. Tried collimating with a pinhole and a torch... Not so good! Anyway...
As I mentioned in my opening, I really believe that the intent is what is important to bring a distinction between what is and isn't EAA. I picked different exposure times and filters depending on what I was wanting to show my friends. I did eventually spend the rest of the night imaging the Antennae Galaxies but that wasn't until we started spending some time physically viewing the universe through a warm poorly collimated dob hehe
My point being that I personally do not see an issue with using a cooled CCD imager for showing the night sky. My QHY9 may have 12s downloads but that doesn't really matter when I am showing off one image while another is being taken anyway. What difference does it make if I take a single 60s exposure rather than 60x1s exposures with a small very low RN "video camera", I have something along the lines of the Atik Infinity or the ZWO174.
