Some of the most picturesque celestial objects are too large to fit in the field of view of an imaging refractor and camera. What’s more, most objects in deep space are very faint and therefore challenging to image without taking very long exposures, increasing the potential for error. Our new Orion 0.8x Focal Reducer for Refractors addresses these obstacles by increasing your refractor telescope’s field of view while reducing the effective focal length by a factor of 0.8x, thereby providing a shorter, more optically “fast” focal ratio to increase astrophotography efficiency. Using the 0.8x focal reducer not only enables your refractor telescope to acquire a larger field of view, but also makes it capable of capturing bright, vividly detailed astrophotos in considerably less time. The Orion 0.8x Imaging Focal Reducer’s fully multi-coated, 38mm clear aperture optics are housed in a sleek, all-machined, anodized aluminum body. Internal glare-threads provide maximum image contrast and brightness. It’s designed for use with any refractor telescope equipped with a 2″ focuser, and requires 55mm of backfocus. Use with a DSLR and appropriate T-ring combination will not require use of any spacers. For use with a CCD astrophotography camera with less backfocus, we highly recommend using the Orion Variable 12-17mm T-thread Spacer Ring (sold separately) to achieve proper distance. You can further enhance your astrophotos by using 2″ imaging filters with the Orion 0.8x Imaging Focal Reducer since it is conveniently threaded for use with 2″ filters. Unit weighs 6.2 oz.

The AmScope T340B-LED-9M digital compound trinocular microscope has interchangeable pairs of 10x and 20x widefield eyepieces, a reverse-mounted nosepiece with four DIN achromatic objectives, Brightfield (BF) LED illumination, and a double-layer mechanical stage. The 9MP camera has a CMOS color sensor, a reduction lens, image capture and editing software, and USB 2.0 output to capture or display still or video images on a computer or projector. The vertical trinocular port can be used to mount the camera. The Siedentopf binocular head has 48 to 75mm interpupillary adjustment, fixed 30-degree vertical inclination to reduce eye and neck strain, and 360-degree rotation capability to provide a more comprehensive view and enable sharing. Bilateral dioptric adjustment accommodates individual eye-strength differences. The reverse-mounted nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil objective provides increased resolution over a standard objective. A reverse-mounted nosepiece keeps objectives out of the way to prevent damage and contamination, and to enable more secure slide handling. A digital compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired, and where image capture, detailed records, or documentation is required.
The 9MP digital camera has a CMOS color sensor for displaying still microscopy images and streaming live videos to a computer or projector. The camera has 40x magnification and a 0.5x reduction lens that ensures that the display has a similar field of view as the microscope eyepiece. The camera can be mounted in a C-Mount or any 23mm eye tube. The camera includes image capture and editing software that provides still image and live video capture and editing capability, including measurement functions. The software supports JPG, TIF, GIF, PSD, WMF, and BMP file formats and is compatible with Windows XP, Vista, 7, and 8; Mac OS X; and Linux. Camera drivers are compatible with Windows XP, Vista, 7, and 8; Mac OS X; and Linux. The software includes Windows APIs for native C/C++, C#, DirectShow, Twain, and LabVIEW that enable custom application development. The camera has a USB 2.0 data port (cable included).
The microscope has Brightfield (BF) illumination that allows the specimen to absorb light, resulting in a dark image on a light background. LED illumination provides bright, cool light for working with temperature-sensitive or live specimens. The 1.25 NA Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen. The double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. Graduated coaxial focus control allows measurements to be taken. The enamel-coated cast-steel body is durable and resistant to stains and corrosion.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

The AmScope T490-DK compound trinocular microscope has a sliding head, a pair of 10x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield and Darkfield halogen illumination, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The trinocular viewing head has a vertical camera mount and a compensation-free binocular viewing head with a pair of 10x widefield eyepieces and sliding head to adjust inter-pupillary distance, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to provide a more comprehensive view and enable sharing. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to re-focus the image. It has an interpupillary range of 55 to 75mm to accommodate individual eye differences, and bi-lateral dioptric adjustment accommodates individual eye-strength differences. The vertical trinocular port accepts a camera with a 23mm or C-Mount adapter (camera sold separately). The forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic optical-glass objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.
The microscope has lower (transmitted, diascopic) Brightfield/Darkfield (BF/DF) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. The dry darkfield condenser has a 0.7-0.8 NA. Halogen illumination provides bright light in a concentrated path and has a rheostat to control light intensity. The 1.25 NA Abbe condenser is mounted on a rack-and-pinion control system, can be adjusted to control the distance of the light from the stage, and has an iris diaphragm to optimize the amount of light illuminating the specimen. The double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. A stage stop prevents the stage from coming into contact with the slide and objectives. The stage is 5-1/2 x 5-1/2 inches (140 x 140mm) and has a traveling range of 2-15/16 x 1-3/4 inches (75 x 45mm). Graduated coaxial coarse and fine focus has a focusing range of 1-3/16″ (30mm) and fine-focus divisions of 0.002mm (0.0000787″) that enable measurements to be taken. Focus knob tension control prevents the stage from drifting out of focus. The solid-metal enamel-coated body is durable and resistant to stains and corrosion.
