More product information

The Celestron PentaView LCD digital microscope uses a 5 megapixel CMOS digital camera with 10x magnification instead of an eyepiece. Combined with its 4x, 10x, 20x, 40x, and 60x achromatic objective lenses in a rotating turret, the camera provides a wide power range of 40x to 600x (160x to 2400x using the built-in 4x digital zoom). The images are displayed on a 4.3" LCD touch screen so groups of people can share the images simultaneously, in addition to their being viewed by a single individual. They can also be transferred to your computer for viewing later via a supplied USB cable.

The Celestron PentaView LCD digital microscope has top and bottom variable brightness LED illumination and a six position red/blue/green filter wheel with three diaphragm openings (1mm, 3mm, and 6mm) for control of the brightness and contrast. Further control is provided by using  the touch screen display to adjust the EV  (exposure value) function of the digital camera sensor. The full color LCD display touch screen rotates 180° (90° left to 90° right) for easy viewing.

There is a mechanical stage with a clamp and directional knobs for moving the subject slide, and dual (coarse and fine) focusing. A universal (100 to 240 volt 50/60Hz) AC adapter if provided for uninterrupted use, but you can also use four user-supplied AA flashlight batteries to provide three hours of use away from an AC power source.

A supplied 4GB SD card will store approximately 1100 snapshots at a 5 megapixel resolution in a JPEG format. You can transfer the images via the SD card to any computer with an SD card slot.  You can capture images at any of the following resolutions: 640x360, 1920x1080, 2048x1152, 2560x1440, 3072x1728, and
3648x2048 (3072x1728 pixels is the maximum sensor resolution, 3648x2048 pixels is the resolution with interpolation).

You can record videos at a 20fps rate at a resolution of 640 x 360 pixels. The display screen will show you the recording time still available as you record.

The Celestron PentaView LCD digital microscope comes with a USB cable, 10 prepared slides to get you started observing, and a hard carrying case.
A telescope collects light and forms a small fixed-size image at a point (called the prime focus) that's determined by the focal length of the optical system. You can see this image by aiming your telescope at something bright, such as the Moon, taking out the eyepiece and star diagonal, and holding a piece of paper behind the focuser. Move the paper back and forth. At some point, you will find a small, but sharp, image of the Moon projected onto the paper. This is the prime focus image formed by the telescope. Unfortunately, human eyes typically cannot focus sharply on an image unless it's more than eight inches from the eye. This makes it difficult to see detail in the small prime focus image formed by the telescope if it's examined solely with the unaided eye. An eyepiece is a small microscope that allows you to get closer than eight inches from that small fixed-focus image -- and the closer you can get to an object, the bigger it appears. A 25mm eyepiece, for example, lets you focus on the scope's prime focus image from an effective distance of only 25mm (one inch away from your eye); a 12mm eyepiece puts you half an inch away; etc. The magnification of an eyepiece is found by dividing the telescope focal length by the eyepiece focal length. A 25mm eyepiece used with a 2000mm focal length scope therefore provides 80 power (2000 / 25 = 80x), making objects appear 80 times larger than they do to the bare eye (or 80 times closer, to put it another way).

Magnification is the ability of a telescope to make a small, distant object large enough to examine in detail. If you look at the Moon (250,000 miles away) with a 125 power (125x) telescope, it's essentially the same as looking at it with your bare eyes from 2000 miles away (250,000 ÷ 125 = 2000). The same telescope used terrestrially will make an object one mile away appear to be only 42 feet away (5280 feet ÷ 125 = 42).
The magnification of a telescope is determined by dividing the focal length of the telescope (usually in millimeters) by the focal length of the eyepiece used (again, usually in millimeters; but in all cases by the same unit of measurement used for the telescope focal length). For example, a 2000mm focal length telescope and a 10mm focal length eyepiece will give you a magnification of 200 power (2000 ÷ 10 = 200). The same 2000mm telescope with a 20mm eyepiece will give you 100x (2000 ÷ 20 = 100).

In geometrical optics, a focus, also called an iimage point, is the point where light rays originating from a point on the object converge. Although the focus is conceptually a point, physically the focus has a spatial extent, called the blur circle. This non-ideal focusing may be caused by of the imaging optics. In the absence of significant aberrations, the smallest possible blur circle is the Airy disc, which is caused by diffraction from the optical system's aperture. Aberrations tend to get worse as the aperture diameter increases, while the Airy circle is smallest for large apertures.
