Alstar 1.25 Flip Mirror for Astrophotography with Eyepiece Adapter

Product Description

In the realm of astrophotography, capturing stunning astronomy images involves more than just perfecting the focus. The Alstar flip mirror significantly simplifies the process of achieving both precise focus and optimal positioning for your astrophotographic endeavors.

Adjusting the Flip Mirror Stop Angle

To adjust the flip mirror, locate the socket head set screw located at the bottom of the flip mirror's body. If your subject appears above the center of your field of view (when facing the rear of the mirror), turn the set screw in a clockwise direction. Conversely, if the subject is below the center, a counter-clockwise turn will be necessary.

Lever Tension Adjustment

Position the flip mirror lever in the "up" setting to enable your telescope to focus on the camera. To switch to eyepiece focus, simply flip the mirror to the "down" position. With the lever upright, adjust your CCD camera focus using the telescope's focuser.

Flip Mirror Lever Functionality

The Alstar features a versatile flip mirror capable of redirecting the light path upwards by 90 degrees or allowing it to pass straight through without obstruction. Start by focusing your CCD camera with the lever in the "up" position using the telescope's focuser. Following that, transition the mirror to the "down" position to direct the light towards your eyepiece. Once there, use the helical focus mechanism to fine-tune the eyepiece focus without disturbing the telescope's original focus.

Connecting with Telescopes

The Alstar flip mirror includes a 1.25" nosepiece and supports coupling with T-threads, ensuring compatibility with a range of telescopes.

Camera Connections

For CCD cameras, most models come equipped with accessible T-threads. If you are using a different camera type, you can easily adapt it by adding a T-ring to your existing setup.

Eyepiece Compatibility

The Imaging Flip Mirror is designed for compatibility with nearly all 1.25" eyepieces, and an adapter is included in the package.

Cleaning and Maintenance

To maintain the cleanliness of the lens, if only minor dust is present, a quick blow from compressed air or a blower bulb will suffice. In the event of fingerprints or smudges on the lens, detach the eyepiece frame from the lens body. Use a Q-tip dipped in isopropyl alcohol or a lens cleaning solution to gently clean the surface. After usage, always replace the dust cover and store the flip mirror in its designated box to prevent further accumulation of dust.

From the brand, the Alstar flip mirror ensures that any object accurately centered in the eyepiece will also be centrally positioned in the camera's field of view. This eliminates the uncertainty of whether the target is perfectly aligned with the camera’s sensor, allowing you to focus solely on capturing breathtaking astronomical images.

For precise focusing, the Alstar flip mirror allows you to direct the light perfectly toward your desired destination. By utilizing this innovative tool, you not only enhance your astrophotography experience but also achieve consistently sharp and well-framed images.
