Bloke from our club shows what can be done using a simple rig ... Canon 70-200mm f4L lens + ASI1600MM Pro + AZ GTe-EQ. He uses the small ZWO guider paired with ASI-AIR.
Being AP it is very un-VA as it's 120 sixty second subs with Ha narrowband filter. But look at the detail he's pulled! And also how extremely wide dynamic range is achieved - M42 core not blown, and neither is Horsehead by Alnitak and other very bright stuff around there.

Howie, I was impressed by your description of the rig by your mate from the club a couple of months back and put together an AZ GTe-EQ of my own. Must admit ,I was a bit put off by the feel of the AZ-GTI in that tilted position and didnt quite finish and have never used it, so I am not in a position to comment yet. All I have to do is attach the losmandy to the EVO 50 and I'm done. So,your post has spurred me on to at least have it ready to go. They are impressive images. I still think the ASIair for us VA'ers is for the single exposures only. That is all you can view on screen at any time. To stack, you have to wait until you are back home on the computer and your favorite AP programs. ....and, to be honest, until ASIair can live stack I will probably keep my little get up and go AZ-GTI setup in the alt/az.
