Quality hardware

The key to any high-quality camera is the ability to convert light collected by the sensor into digital information while ensuring that as little noise as possible is added. The digital image needs to truly reflect the light collected. The Atik 383L+ achieves this, by having:

• Very low read-noise, 7 electrons, on par with many Sony sensors, enabling faint details to be detected.
• Great linearity, with a regression correlation coefficient of R = 0.9998 over the range of 1,000 to 64,000, making the camera suitable for sensitive photometric measurements.
• The bias frame histogram from the camera shows the ideal Gaussian shape, indicating that maximum detail can be extracted on processing.

The Atik 383L+ is a dream combination of low-noise electronics and a scientific-grade sensor that we are able to offer at a fantastic price. Whether you are an established imager or are just starting, the Atik 383L+ is a great choice.

Highlights:

• Ideal for visual observation and astrophotography.
• Designed for the amateur astronomer or photographer who wants to view and photograph the moon, planets, and deep sky objects.
• Features FPL53 "super" extra-low dispersion (ED) glass in a fully multicoated apochromatic lens system that corrects for both spherical and chromatic aberrations, astigmatism, and off-axis comas.
• This correction creates a wide flat field of view without distortion and removes the blue-tinted halo effect for true high-contrast color transmission.
• Can accept both 2" and 1.25" eyepieces and accessories for visual use.
• Threads on the drawtube allow direct connection of T-rings and other camera mounts.

A ring spacer placed around the objective lens refines star images beautifully in astrophotography.

In the previous SD81S model, a set of three tiny tin foils are placed around the objective lens as a spacer between the doublet lens. The end of the tin foils protruding over the objective lens obstruct the incoming light. As a result, the protruding tin foils make the light of diffraction of stars chipped radially. Exchanging the tin foils for the spacer ring makes the diffraction of the stars' light equal. It allows you to create more refined and beautiful star images in your astrophotography.

The SD lens suppresses residual chromatic aberration far below the threshold of visibility.

A lens of refracting telescopes has chromatic aberration which is caused by different wavelength of visible light (colors) focusing at different distances. The Vixen SD lenses, made of FPL53 super extra-low dispersion glass, allow for correcting the chromatic aberration over a wide spectrum of light. The SD81SII delivers outstandingly sharp images with high contrast for both visual and photographic applications. Moderately bright F7.7 images will satisfy the most demanding visual astronomer or astrophotographer.

A short optical tube in length is handy for not only visual observation but also astrophotography.

The ED81SII optical tube has a moderate short length to enable you to carry and set it up readily. Also, a lightweight optical tube allows you to balance it with fewer counterweights. The ED81S comes equipped with a metal carry handle and the Vixen standard dovetail slide bar M for quick attaching and detaching. The provided Flip mirror diagonal switches incoming light to allow for using two eyepieces of different magnifications alternately. Also, you can install a camera on the straight side and view an image through an eyepiece on the right-angled side of the flip mirror diagonal.

Full-frame imaging with a DSLR camera.

Using an SD reducer HD kit or an SD Flattener SD kit, which are available optionally, the SD80SII provides an image circle of 44mm, adequate for taking photos with a DSLR camera. (Photo) M8, M20 nebulae taken with Vixen SD81SII with SD reducer HD kit (compound focus 496mm) and Pentax K-1 at ISO1600, 49 minutes exposure.

Optional accessories to expand your pleasure of taking astrophotography.

SD Reducer HD Kit: This kit includes a flattener lens to be combined with a reducer lens for a flat and wide imaging field when you use them with the SD81SII, SD103SII, or SD115SII optical tube. The reducer lens reduces a focal length by 0.7X. Direct Wide Photo Adapter 60DX: It is available for Canon EOS or Nikon DSLR cameras. It is possible to change the orientation of a camera for a framing of the photographic field.

Wide Photo Adapter 60DX

High precision camera adapters for prime focus astrophotography are optionally available for Canon EOS and Nikon. The Wide Photo Adapter 60DX is designed to be an integrated camera mount reducing vignetting to the maximum. They are highly effective with full-frame DSLR cameras, and can be used with SD series refractors (in combination with the SD Reducer HD Kit or SD Flattener HD Kit).
