Hi Paul,
Thank you for taking time to show us the comparison.
I looked quite carefully at both images and could definitely notice sharper stars in the image acquired with AOX, in particular in the central region with faint stars with the galaxy in the background. Also, I have noticed better star separation - with two bright stars near the galaxy, one has a faint "companion". Not sure why but in the image without the AOX, stars seem to have more distinct halos.
IMO from WIHS the AOX is a whorthwhile investment. Small improvements at each stage of creating an astroimage do add up and inevitably help to elevete final compositions to new heights.
I was looking into getting an AO unit from SX, but I would not be able to reach correct spacing with my current setup, so I dropped that idea. Maybe with my next scope...
