Interesting GSO mechanical design
The adaptor does look nice, really itching to try it out.
An interesting point that Joshua pointed out while doing the design is that in the basic GSO setup, the complete baffle tube + mirror + image train assembly, which would weigh a few kilos and be upwards of 600mm long, is attached to the OTA via only the 3 (three!) 4mm mirror collimation hex screws, leading to the possibility of collimation change due to flexure as OTA elevation varies. You can see the three (inner) screw holes in the attached photo.
That's why his adaptor uses NINE attachment points to the backplate, ensuring the image train is solidly mounted to it while totally offloading it from the mirror assembly, so the mirror collimation screw load is significantly reduced to just the mirror and baffle tube.
I believe Joshua's adaptor should provide significant improvement to the overall collimation stability and imaging load carrying performance of the unit.
