To obtain the approximate inside diameter of a tube (if it is not provided), subtract the wall thickness from the outside diameter twice. Aluminum is for telescopes. We can also supply aluminum tubes which incorporate a process that provides even greater rigidity at the 2 ends of the tube where it is required most.

It holds all the optical parts in alignment, it shields the optics from light and physical contact that might damage. The tube is cut to length while still on the mandrel to assure squareness. A reflecting telescope has sources of warm air (temperature difference between the mirror and / or tube to the ambient air) inside the tube.
The minimum tube diameter is determined b y mtd = 2 * d2e * tan (tf / 2) + d + 0. 5 where the d istance (d2e) is from the primary mirror face to the end of the telescope tube. The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. It really is a very good source of information and advice for anyone building fast telescopes. One of his recent project is a 10. 5 inches f2. 7 dobsonian telescope.

This episode in our Vintage Telescopes Masterclass series looks at the method employed in Britain for the manufacture of precision brass telescope tubes from the latter half of the 18th century until the closing decade of the 20th. Much has been written about the instrument makers of the 18th and 19th century and the design and construction of the optical glassware employed in their telescopes. But the methods employed in the manufacture the brass tubes and other parts so vital to the positioning and adjustment of the optics has received much less attention. The volume production of high precision brass instrument tubing played an…
This is the first in a series of three videos in which I describe the process necessary to make a tube for the optyical assembly of an eight inch Newtonian Telescope mounted with a Sidewalk Telescope
by Apostolos Spanakis-Misirlis At: FOSDEM 2020 video.fosdem.org/2020/H.2215/pictor_radio_telescope.webm PICTOR, located in Athens, Greece, consists of a 1.5-meter parabolic antenna that allows anyone to make continuous and spectral (i.e. hydrogen line) drift-scan observations of the radio sky in the 1300~1700 MHz regime for free. The goal of this effort is to introduce students, educators, astronomers and others to the majesty of the radio sky, promoting radio astronomy education, without the need of building a large and expensive radio telescope. PICTOR is a fully open source (software & hardware) project: …
