Wallace the 6 inch f/2.8 telescope, building it, and hiking with it

A blog post details the construction of "Wallace," a custom 6-inch f/2.8 telescope designed for backpacking and hiking, covering the building process and field-testing results.

Background

- Lucas Sifoni is an independent Swiss watchmaker and optician who builds custom, high-end optical instruments, blending precision mechanics with traditional craftsmanship. <br>- "6 inch f/2.8 telescope" refers to a Newtonian telescope with a 150mm-diameter mirror and a very "fast" focal ratio (f/2.8), which makes the tube unusually short and portable for its light-gathering power — a challenging design that requires extreme precision in the optics. <br>- "Hiking with it" signals that the author values both instrument-making and practical, rugged field use; this is a build log for a compact, travel-friendly telescope that he actually carries into the wilderness. <br>- The project sits at the intersection of amateur telescope making ("ATM"), fine horology, and DIY fabrication; readers interested in any of those fields will appreciate the craftsmanship constraints involved.
