NT114CF Magnification Review

Magnification is one of the key factors to consider when reviewing any telescope and the NT114CF is no different. We can measure the actual magnification of the telescope by dividing the focal length of the telescope by the focal length of the eyepiece.

The NT114CF includes two different eyepieces, one with a 9.7 mm focal length and another with a 26 mm focal length. Since the focal length of the telescope is 500mm, then we get 19.2x magnification (for the 26mm eyepiece) and 51.5x magnification (for the 9.7mm eyepiece).

As discussed, you also get a Barlow lens in the package, which will double the magnification to 38.4x and 103x, respectively. To do this, simply place the Barlow lens to the eyepiece holder (before the eyepiece), then slide in the eyepiece into the Barlow lens’ slot.

The inclusion of these two different eyepieces and Barlow lens is actually pretty generous since you get more versatility from the whole package.

High magnification is preferred for lunar observation and for observing the planets, in this case, we can use the 9.7mm eyepiece (with the Barlow lens if necessary).

On the other hand, lower magnification can provide a wider field of view, so it’s better when observing deep space objects like nebulae or further galaxies.

You can help secure the phone with a rubber band or other fasteners if you want, but we’d recommend getting a better adapter if you really want to use your phone with the telescope.

How Do I Collimate this Telescope?

Since this is a Newtonian reflector telescope, you will need to collimate it every now and then. Collimating a telescope is a crucial process to ensure its optical components are properly aligned for optimal performance.

Think of collimation like routine car maintenance: once the images got out of focus, there’s a huge chance that you’ll need to collimate the telescope. With the NT114CF, collimation is pretty easy since the primary mirror is already factory-collimated and is mounted permanently.

Here are the steps to collimate your telescope:

Step 1: Choose a well-lit and stable location for collimating your telescope. Avoid windy conditions that may affect the collimation process.

Step 2: Replace the standard eyepiece with a collimation cap or collimation eyepiece. This specialized eyepiece aids in aligning the telescope’s optical components.

Step 3: Look through the collimation cap or eyepiece and center the secondary mirror in the field of view. Use the flathead screwdriver to adjust the secondary mirror’s tilt screws until it appears centered.

Step 4: While still looking through the collimation tool, adjust the primary mirror’s collimation screws to center the reflection of the secondary mirror. Ensure the reflections align precisely in the center of the field of view.

Step 5: Rotate the collimation cap or eyepiece and check that the reflections remain centered throughout the rotation. Adjust the primary mirror collimation screws as needed to maintain alignment.

Step 6: Refine the collimation by examining the concentric rings of the reflected light. Make small adjustments to the tilt and collimation screws until the rings are symmetrical and concentric.

Step 7: Look through the collimation cap or eyepiece again to confirm that the reflections remain centered. Repeat the process if necessary until the collimation is precise.

Step 8: Once satisfied with the collimation, tighten any locking screws on the secondary mirror holder and primary mirror cell to secure the adjustments.
