300mm Serrurier build


Recommended Posts

Hi everyone,

I am building a 300mm serrurier truss (ST) right now as a winter project. I have attached a couple  picture of my progress to date.


I started out wanting to build a newtonian ST version of the tube to use as an imaging instrument for astro-photography. A 300mm  F/5 would have been glorious!

Unfortunately, halfway through the build, I realized that the tube assembly exceeded the payload weight limit on my mount by about 5 kg.

So I decided to build a dobsonian version instead. I still have to build the rocker box and paint the entire thing.

Clear skies,
