Interesting fix, the question is will it work in the field, I had done some surgery on my tube, so from memory I had a minimal amount of extension with the regular GSO focuser the low profile version just didn't have enough support. If you are using the 12 inch tube you will find by applying a bit of weight to the end of the focuser the tube will distort. I beefed up mine with a stainless flange, but it needs to be big and rigid, I felt in the end that an off axis guider or an SBIG type inbuilt guider would eliminate flexure from a side by side setup, I found 6 min exposures was as long as I could reasonably expect without some movement, I did try various aspects of angle of the focuser in relation to the direction of travel.... Didnt help much. Being as I have been through what you are doing, I will be most interested in your progress
