60mm aperture astronomical telescope accessories objective lens focal length 360,500,600,700,800,900

60MM series, focal length: F360,F500,F600,F700,F800,F900

Caliber: 60 MM (the actual outer diameter size of all lenses of 60 series is: 62 mm)



Focal length: 360,500,600 ,700,800,900 MM



This objective lens is designed with double separation structure, separating the outermost layer and innermost layer of the blue film objective lens with blue film plating. Buy it and get a spacer ( double separation without spacer will seriously affect the imaging effect).

The following figure shows the 60-caliber special objective lens base, made of high quality plastic, suitable for matching our 62mm diameter objective lens. It can be used with 63pvc tube as mirror tube, there may be a little error, just use sandpaper to polish it slightly.

60 caliber long and short focusing base, high quality plastic material, outer diameter of the lens tube connection 60mm, please choose according to the focal length of your objective lens.

The following figure shows a 60mm long focusing seat, which can be adjusted from 0 to 120mm and is suitable for the focal length objective lens above 500mm.

The following figure shows the 60mm short focusing seat, with an adjustable range of 0-45mm, which is suitable for the objective lens below F500 focal length.

Plossl prozin eyepiece: Also known as symmetrical eyepiece, it is significantly better than K (kineer) and H (Huygens) eyepiece. It consists of two identical groups of double glued achromatic lenses, which successfully controls chromatic aberration and spherical aberration, and reduces ghost images and field songs to an imperceptible degree, its parameter performance is equivalent to the excellent OR Abbe non-distortion eyepiece, but it has a larger exit pupil distance and a flat field of view of 40-60 degrees, with lower cost, and is suitable for all magnifications, it is currently the most widely used eyepiece. Calculation of magnification of astronomical telescope magnification = objective focal length/eyepiece focal length example: Boguan beta 80900 astronomical telescope with a focal length of 900mm and PL10 10mm Pross eyepiece magnification = focal length of objective lens 900mm / PL10 focal length of eyepiece 10mm = 90 times other focal length eyepieces, and so on. Pl6.5 eyepiece, 1.25 inch interface, 6.5mm focal length.

Standard proelement eyepiece for astronomical telescope structure: symmetrical four pieces and two groups of double gluing interface: standard interface 1.25 inches material: aluminum alloy + optical glass coating: Full-surface multi-layer Broadband Antireflection film/FMC extinction: internal extinction thread packing: Spiral quick storage tube

Pl10 eyepiece, 1.25-inch interface, 10mm focal length

Pl20 eyepiece 1.25 inch interface, 20mm focal length

Pl30 eyepiece, 1.25 inch interface, 30mm focal length

5x 24 star finder 5x 24 optical star finder, suitable for star finder of small caliber astronomical telescope, with star finder lens base. Star-seeking mirror, a small telescope with small light force attached to a large telescope, is used to help observers find the position of celestial bodies. Star Finder is a refracting telescope specially used for visual Star Finder, which is attached to the main telescope barrel to search for celestial bodies to be observed. Its function is to guide the celestial body to be observed to the center of the field of view of the main telescope. Star Finder generally adopts double separation or double glue objective lens, and the focal plane is disposed with a dividing plate for aiming.

Multiple: 5 Times caliber: 24mm the star finder mirror is not installed and can be used. It needs to be debugged to ensure that it is consistent with the target seen by the astronomical telescope. In this way, the real role of the star search mirror can be played.
