Greg,
As you know the MMOAG came with a helical focuser and a shorter 1.25" nosepiece holder.
Could not attain focus with the helical focuser, distance is just too far.
The 1.25" nosepiece holder was better but still could not get focus.
The remote guide head was bottoming out and could not get any closer, which meant that I had to increase the distance between the STL imaging chip and the prism by getting a longer STL-MMOAG adpater.
I ended up getting the .5" adapter from Astrodon, this way I have plenty of room to manoeuvre the RGH to get focus.
Lost .5" of back focus so I have another .5" left, but thats not a big deal as the CFZ of the FSQ is 55 microns.
Need to make up spacer(s) that will go around the RGH nosepiece so when RGH is inserted into the MMOAG it gets it near focus every time.
