Hi Jo,
That looks great. very nice work.
yes, goto mounts are very handy. does this mount have an autoguider port or support guiding?
I had two suggestions, pretty sure you've already considered these.
Looking at the pics, if you keep the focuser to one side, it'll end up in odd positions when slewing to different parts of the sky and you'll have an issue with balancing the weight.
is it balanced with the eyepiece?
if you had the find on the other side, that could even it out.
I believe this is for visual use?
its common to have the focuser facing down as that way, balancing in RA is not an issue.
second thing, do you have plans to make the two fasteners removable or adjustable? reason being you'll have to rotate the tube at some point if you use a different eyepiece that's lighter or heavier or even a camera.
so you'd need to loosen the fasteners, rotate the tube with the camera and then fasten it. I noticed both sides have bolts?
you would also need to loosen it if the OTA needs to be slid up or down again due to differing weights with cameras and eyepieces.
I like the idea of two holes for the mirror cell.
Nice work
Alistair
Edit: one other thing you could do is add a wing nut and a nyloc nut underneath it to the collimation bolts.
that way, you won't need a tool to adjust the bolts. you never know when a re-collimation is needed in the field.
Any provision for mounting a dew controller? that'll also be required to keep eyepieces and/or the finder objective dew free. else its a nightmare cause things dew up very fast.
