TS Photo dovetail bar EQ5-Level with oblong holes and photo thread The dovetail bar PS30 enables the adaptation of telescopes and spotting scopes to mounts with GP-Level quick release coupling as well as to suitable dovetail clamps. The profile design reduces weight and also vibrations. The special shape of the surface allows the connection of flat surfaces (tube clamps and top plates), but also of round surfaces (telescopic tubes). The dovetail bar is particularly flexible: The dovetail bar has two elongated holes. Thus the distance between the pipe clamps can be varied. The holes are suitable for M6 and 1/4" screws. The screw heads are recessed in the rail. The thread length of hexagon socket screws should be at least 13 mm. The prism rail also fits photo tripods and tilt heads: The dovetail bar has a 1/4" female photo thread exactly in the center. This means the bar fits on photo tripods and tilt heads. You can also use it to mount your telescope or spotting scope on a photo tripod. The dovetail bar enables effective weight compensation if the spotting scope is top-heavy, for example.

Product description TS Optics dimmable LED Flashlight with red and white light The energy-saving LED torch is an essential piece of equipment for all amateur astronomers. The brightness is fully dimmable with a rotary knob, from a dim glow which does not dazzle to maximal illumination for searching items on the ground. And if red light is not sufficient anymore, you simply switch to white light. Very practical is the carrying cord. With it, the flashlight has its own place during the night. Power consumption is very low. A test with the flashlight switched on showed that it began getting dimmer not until after about the fourth day. Supplied is a commercially available 9-volt battery which is simply replaced if needed. Delivery contents LED flashlight with carrying cord

GSO Mirror Set for Self-Construction of a 16" f/8 RC Telescope The mirror set consists of a hyperbolic primary mirror and a hyperbolic secondary mirror for the construction of a Ritchey-Chretien telescope. The main mirror has small shell fractures around the center hole, but these are in the shadow of the secondary mirror aperture tube and thus have no negative optical influence. Main mirror: diameter 400 mm bore 120 mm, edge thickness 44 mm, center thickness 40 mm, weight 10.75 kg ; secondary mirror diameter 176 mm with edge thickness 18 mm , weight 1 kg ♦ With the mirror set you can build an RC telescope with 406 mm aperture and 3248 mm focal length. ♦ The set consists of primary mirror and secondary mirror without mechanical accessories ♦ The mirrors are made of quartz glass (similar to Zerodur) for stable focus position. ♦ 99% reflectivity on main and secondary mirrors with a quartz protective layer
