When imaging I dont use the diagonal at all - the less glass for the light to pass through the less chance of something dodgy happening to it - dirty lenses etc

Andrew,
Your Barlow weighs less than your diagonal? I would check that as the weight of the diagonal+EP has got to be more than the Barlow+EP. This would especially be true of a prism Diag. I am just curious as my 2" Diag+ EP weighs A LOT more than the Barlow+EP. The least impact on balance and stress will come with the weight being placed as close to the center of the base/Forks as possible. In your arrangement the weight is moved out the difference in distance between the length of the barlow and the diag. Of course, all this is mute if the image is truly clearer with the Bar. first. The stress imparted is in no way great enough to allow it to impact visual performance. Like I said, just an observation I have made.
