To try and get more use out of the 8" Airylab HaT I decided to make some cardboard masks to stop down the aperture to make it more usable in less than ideal seeing conditions.  I made 2, a 175mm and the one I used here which is 155mm.  While the conditions we're ideal on one of the hottest days of the year it did produce a usable image and holds potential for greater use in the future.
