That's a shame it doesn't fit.

Try focusing a star in one of the better corners and then noting the position and then focusing on a star near the centre and see if there is much difference.

The Nitecrawler focuser that Moonlite make for the FSQ106 has a recess that the rear lens element from the FSQ can slip into. If I'm going to replace the focuser then I will lash out and get the Feather Touch one. I would like to make that pesky CAA go away but I don't know how I can do this without replacing the whole focuser any way.

I have a few more things which I am going to try tonight whilst it is clear (albeit with some moon about). I'm interested to spend a little extra time making sure that the focus is correct by zooming in on the stars in the centre of the image. I want to be sure that the radial stars in the corners were not affecting the focusing.
