Description

SVBONY SV112 1.25" Fully Metal Deluxe Variable Eyepiece Projection Kit for Telescopes Black
Description
This Deluxe kit includes the parts you will need for both "Prime Focus" and Variable "Eyepiece Projection".The "Variable" feature lets you adjust the adapter length to vary the magnification (thus image size) for perfect framing of your shots. 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. CNC machined of aluminum with a durable black anodized finish. The 1.25" barrel is threaded to accept standard 1.25" Eyepiece Filters.

Built-in protective pressure ring to prevent the appearance of eyepiece barrel from being scratched
The kit is suitable 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.
Eyepiece Projection & Variable 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. A "Variable" Projection adapter allows you to change the projection distance. This varies the magnification of the system, allowing you more flexibility when framing your shots. Think of it as a "Fine" magnification control. Whereas "Coarse" changes in magnification are made by changing eyepieces. Eyepiece Projection is typically used for Terrestrial, Lunar & Planetary imaging and any time higher magnification is needed to bring out detail.
Important Note:
Additional parts may be required to reach photographic focus with certain telescope types: SCTs and Maks generally have enough focus range without any additional optical or physical extensions.
Reflector type telescopes will typically require the use of a Barlow Lens
Refractor type telescopes will typically require the use of an Extension Tube
The Eyepiece upper barrel can be no larger than 42mm in diameter.
