First Image with the Notatakahashi

I have been working on a prototype Maksutov Newtonian reflector telescope (Mak-Newt) that I bought recently in disassembled form, in an attempt to bring it back to life. Now called the "Notatakahashi Mak-Newt Astrograph", it is a 152mm aperture, 600mm, f4 wonder. I have been working to figure the optimum configuration for the front menicus lens, the position of the spherical primary, and the ideal point of prime focus outside the tube. I believe I am getting close, as I was able to shoot an image of the moon through the hole where the focuser will be installed. This image was shot hand held, without the help of the focuser. The colors and contrast look pretty good, so I am pleased with this configuration.

This image of the full moon was taken with the Notatakahashi Astrograph.
