## Overview

The Astromania 1.25" Extendable Camera Adapter is a precision-engineered, dual-function astrophotography tool that fits standard 1.25" telescope eyepiece holders. Made from black anodized aluminum, it offers variable projection distance for adjustable magnification without swapping eyepieces. Compatible with both refractor and reflector telescopes, it supports prime-focus and eyepiece-projection photography, and includes threading for standard astronomy filters. Ideal for millennial astro-enthusiasts seeking professional-grade imaging flexibility.

## Description

The Astromania 1.25" Variable Universal Camera Adapters allow attachment of a camera body to reflector and refractor telescopes for either prime-focus or telescope eyepiece-projection photography. The adapter's 1.25" nosepiece slides into the telescope's eyepiece holder just like an eyepiece. This Variable Universal Camera Adapter is composed of two detachable parts: a prime-focus adapter (or "T-adapter") for prime-focus photography, and a fixed-length or variable extension tube for eyepiece-projection photography. A thumbscrew in the extension tube holds the telescope eyepiece in place. This combination of prime-focus and eyepiece-projection camera adapter has a sliding barrel design that allows variable projection distances. This allows for slight changes in magnification without swapping telescope eyepieces when performing eyepiece-projection photography. Fits reflector and refractor telescopes with 1.25" eyepiece holders. The Variable Projection Camera Adapter allows for a continuous range of projection magnifications during eyepiece-projection photography for telescopes with a 1.25" focuser.The machined sliding-cell assembly can be fixed at any position along its length and is held in position via a thumbscrew. The resulting effective focal ratio is then determined by the sliding adjustment and eyepiece used. A T-ring specific to your D/SLR camera is required to connect your camera to this adapter (not included).

## Features

- Zoom Projection and Focal Adapter: The simple way to astrophotography begins with this projection adapter; use your standard Ploessl or Kellner 1.25-inch eyepieces for beautiful photos of the Moon and planets
