Oct 14, 2010 · I took a single 30 seconds shot to Pleiades open cluster (M45) using my 6-inch Sky-Watcher achromatic refractor that costs around 1,000 US$. Then I used a 6-inch apochromatic Takahashi TOA-150 that costs around 10,000 US$ to take an equivalent shot on the same field. Resulting images speak by themselves.

Achromatic Lenses are ideal for a range of applications, including fluorescence microscopy, image relay, inspection, or spectroscopy. An Achromatic Lens, which is often designed by either cementing two elements together or mounting the two elements in a housing, creates smaller spot sizes than comparable singlet lenses. Apr 03, 2008 · Why a 6-inch F/15 Refractor? From my years of experience as an astronomer who has used a variety of telescopes of different types along with using very rare large apertures of 8-12 inches. I have found the 6 inch F/15 refracting telescope is the optimum design for lunar, planetary, and solar obse... The drawbacks are these: if you make the most obvious version of the lens, there will be a visible ghost from the R3/R2 reflection (my 6" f/15 Clark-type lens shows this strongly around Jupiter and Sirius). To get rid of this ghost, you'll either need to coat the lens or make the difference between R2/R3 greater.

Great refractor refers to a large telescope with a lens, usually the largest refractor at an observatory with an equatorial mount.The preeminence and success of this style in observational astronomy defines an era in modern telescopy in the 19th and early 20th century. The lens is a sealed MgF2 coated achromatic lens of the highest quality. Lens cell collimateable. Fully baffled and flocking front and rear. Rotatable 2" Moonraker focuser with turned tube plug. 30mm x 6 finder scope. Tubes from 6082T6 grade aluminium, hand polished. Long flocked dew shield reduces the chance of the front element fogging.

An Achromat, or Achromatic lens, is usually made up of multiple optical elements, which can be air-spaced or cemented together. These typically alternate a positive lens of low index material, such as crown glass, and a negative lens of high index material, such as flint glass.

Telescopes delivered (as this one) with UNIHEX would accept one optional 1.25 inch eyepiece. By 1963 Unitron included a new Achromatic Amplifier with the telescope, this is a negative or 'Barlow' lens that could be attached onto the barrel of the UNIHEX or the standard extension sleeve. Refractors are No Good! (The Case Against Refracting Telescopes) By Jim Fleck. Illustration courtesy of Stellarvue.

A few words about each of the telescopes involved. The Jaegers dates from the late 1970s and has been a humble and lovable companion on many occasions since. However, its objective lens is not exemplary, showing enough astigmatism to impact its performance at high powers. Achromatic doublet lenses are excellent focusing components to reduce the chromatic aberrations from broadband light sources used in many analytical and medical devices. Unlike singlet lenses, achromatic lenses have constant focal length independent of aperture and operating wavelength and have superior off-axis performance.

The size of a refractor telescope’s objective lens (aperture) determines a telescope’s viewing power. A larger objective lens captures more light and hence is able to view objects that are fainter with better clarity. Initially, refractors used to have a single objective lens.

Finally, the jumbo size 2-inch barrel is used with large Dobsonian reflectors and quality apochromatic refractors. These oculars provide ultra-wide fields of view and accordingly, with few exceptions, are available only in longer focal lengths. A telescope with a 2-inch focuser accepts 2-inch eyepieces, and, with an adapter, 1.25-inch models.

All types are offered in a 4inch, 6 inch and 8 inch diameter and are not polished. Each achromat set can be purchased with or without the glass tooling. The blanks and the tooling have been machined to the starting curve. Telescopes delivered (as this one) with UNIHEX would accept one optional 1.25 inch eyepiece.

Lenses with a M12x0.5mm thread are officially called S-Mount lenses, though "M12 lenses", "M12x0.5 lenses" or simply "board lenses" is more commonly used, as they are often used with board cameras. They are the most common "mini lenses".
