Description

Special eyepiece fits in 11/4 inch eyepieces or diagonal The eyepiece is more accurate than the simple collimation tool. For aligning the optics of Newton reflectors, Dobson reflectors and Schmidt-Cassegrain telescopes (SCTs) With dustproof and moisture-proof rubber cover, professional design, CNC machine, precise surface processing. When collimating a refractor, you should put the cheshire directly into the pull-out.; Product description The SOLOMARK Cheshire eyepiece has a wide rim on which it rests when inserted into the eyepiece extension of the telescope. This ensures exact alignment of the cheshires, so that the collimation result is accurate even when it plays between the cheshire and the eyepiece extractor. Newton telescopes: insert the Cheshire into the telescopic extension like a normal eyepiece. Turn the porthole sideways towards the light source and look into the hole of the eyepiece. Once the reticle and reflection of the secondary mirror are concentric, the telescope is properly collimated. Refractors: As you see through the grind, you will see as many reflected discs as there are glass-to-air surfaces. (Example: an air-distributed double refractor shows four reflective discs, of which are usually two brighter.) Once all rings are concentric, the telescope is perfectly collimated. A slight misalignment is usually not a problem, but if the rings are drastically eccentric, the telescope should be refilled. Practical advice from Solomark: when colliming a refractor, you should place the Cheshire directly into the eyepiece extractor. Do not use star diagonal, which may be slightly wrong with itself. You need to hold the lens cap on the eyepiece extension, otherwise the image will be too bright and you will not see the much weaker reflections. When collimating a Newton telescope, we recommend rotating the telescope until the eyepiece extension looks straight up, and then insert the cheshire without locking it. This prevents the Chinese tap from being easily tilted out of the axle.; Product description The SOLOMARK Cheshire eyepiece has a wide rim on which it rests when inserted into the eyepiece extension of the telescope.
