Fully metal telescope eyepiece adapter of four different size suitable for almost all the eyepieces

• Designed for Canon EOS & Rebel SLR & DSLR Cameras and Photography; Note:it doesn't fit for EOS-M models; Connect camera to telescope for direct prime focus photography convenient and easily;
• The camera adapter kit for prime focus; In this imaging method the camera is connected directly to the telescope and placed at the "prime" focus of the telescope; The telescope becomes the camera lens. no eyepiece is used in this method; This method provides the widest possible field of view, the shortest possible exposure time and moderate magnification; Typically used for imaging nebulae; galaxies and other large (but dim) deep sky objects;
• The camera adapter kit for eyepiece projection; In this imaging method an eyepiece is used to increase magnification; The eyepiece is placed between the camera and the telescope; The eyepiece “projects” the image onto the camera sensor; The projected image size increases with distance; Similar to a flashlights beam;
• Fits telescopes with a standard 1.25" eyepiece port; The adapter can hold eyepieces up to 42mm in upper body diameter; It also features a laser engraved extension scale for recordability and repeatability as well as a large machined grip ring; For a sure grip in even the worst dew conditions;
• The variable feature lets you adjust the adapter length to vary the magnification (thus image size) for perfect framing of your shots; The 1.25" barrel is threaded to accept standard 1.25" eyepiece filters.

Note: It can be compatible with maximum eyepiece diameter is 42mm

• The filter made from high-grade glass with dichroic interference and antireflection coatings;not only useful at light-polluted sites; the contrast is also increased at dark sky sites;it can be used with all 2" eyepieces
• Narrowband filter do not eliminate the effects of light pollution or increase the object’s brightness;in many cases, they increase the contrast between nebula and night sky, not brightening the nebula
• The 2" O-III filter useful for large aperture telescopes through which the light of the Moon can be extremely overwhelming. Allowing just for the Double Ionized Oxygen lines between 495.9nm to 500.7nm to pass through at 90%
• Astrophotographic;The filter enhances contrast during visual observation of gaseous and planetary nebulae in all sky conditions; 2" filter allows high-contrast imaging even in areas with strong light pollution
