A 18 to 20-inch Dobson telescope isn\u2019t something you just move around. Usually such a telescope is fixed in the shed, the observatory or under a shelter, and then you want to properly cover it between two evenings. The TG-5D from Telegizmos is a cover for a 20-inch or 18-inch Dobson telescope.<\/p>\n\n\n\n
At Dobson telescopes<\/a> These sizes often involve truss models or large fixed tubes. So be sure to pay attention to the shape of your telescope when you cover it up.<\/p>\n\n\n\n With these large telescopes, it pays to measure precisely. Look at the height in the position where you set the telescope down and at the width of the base, and compare that with the dimensions of the cover. Only put the cover on when everything is dry, and occasionally air it out on a dry day.<\/p>\n\n\n\n There is also a Astrozap dust cover for 20 inch Dobsons<\/a>. If you have an even larger Dobson, then look at the cover for 24 to 25 inch Dobsons<\/a>.<\/p>","protected":false},"excerpt":{"rendered":" Telegizmos cover for a large 18 to 20 inch Dobson that is
