Web1 day ago · This is while the lattice model predicts wider and longer fracture (width of 0.74 i n and half-length of 56.4 f t) compared to the P3D model (width of 0.64 i n and a half-length of 47.6 f t ). The generated net pressure due to TSO is in the order of 432 p s i for lattice simulation and 466 p s i for the P3D model. WebThe R130SF from Vixen is a 5.0" Newtonian reflector telescope with a focal length of 650mm. Delivering excellent light throughput and resolution via its f/5.0 aperture, the R130SF provides clear views of deep sky objects, nebula, clusters and galaxies. This fine optical instrument comes configured with mounting rings, a dovetail plate, and a ...

In the case of an 8-inch f/6, L is often about 9 inches. Dividing 9 by 6 gives a minimum secondary size of 1.5 inches. The same telescope with a low-profile focuser rather than the standard tall rack-and-pinion model might have L as little as 6 inches. ionetwork.com
Astro-Tech 6" F/4 imaging Newtonian optical tube
WebOct 1, 2013 · Posted September 30, 2013. The F/4 will have a shorter focal length (obviously !) and therefore can show a wide field of view. The collimation "sweet spot" of the F/4 is a lot smaller than an F/5 so accurate collimation and mechanical construation that maintains that is even more critical at F/4. An F/4 shows quite a lot more coma than an F/5 ... WebTS-PHOTON 8" f/5 Advanced Newtonian Telescope OTA with Metal Tube. £489.00 Add to Basket.
