  1. initially, I had the idea to make a binoscope with a fixed interpupillary distance. Print on 3D printer detail, as in the figure. The detail of this positioning between two 50ED. Pull it all off with some kind of tie. In the base of the detail insert the nut under the photo screw 1/4-20.

  3. The weather here does not contribute to the observation of the sky. We have to look through 3 glasses.
  4. ghYes, I ordered the rings to the local Miller.
  5. I can't check mount in yet. The area between the rings is too narrow. Waiting for the Miller.
  6. Purchased for maximum magnification zoom eyepiece 2-4 mm. Increase with it accordingly 61-69-81-97-121х. The field of view of 0.4 - 0.8 degrees.
  7. The diaphragm was shifted by 11 mm. with the help of a barrel from the eyepiece 30/80. Put barrel on the table. On top put the tube and pressed. Painted over the entire surface to the diaphragm with a black marker.
  8. My theme on Russian astronomical forum https://astronomy.ru/forum/index.php/topic,166696.120.html

  10. The previous question is no longer relevant. Cut off 30 mm from the side of the lens. All the necessary eyepieces reach the focus. It remains to move the diaphragm.
  11. The diaphragm has an internal diameter of 40 mm. it is now 40 mm from the edge of the nearest lens. How far should I move the diaphragm? Let me remind you, the aperture is 50 mm, the focal length is 242 mm.
