Many H-Alpha imaging setups encounter issues like Newton Rings or interference fringes due to flat optical surfaces within the imaging train. However, by positioning the camera at an angle to the optical axis, these interference patterns can be effectively eliminated.

A coma corrector serves as a corrective lens designed specifically for Newtonian telescopes. These telescopes often induce distortion at the periphery of the field of view, causing stars to appear comet-like, a phenomenon known as 'coma'.

The SynGuider revolutionizes equatorial mount guiding by eliminating the need for a PC or laptop, streamlining astro-photography sessions and ensuring perfectly round stars during long exposures. Supplied with a guiding handset & cable, serial cable, and battery pack, it operates independently, requiring only 4 x D-Size 1.5v batteries or an alternative power supply meeting DC6v-12v specifications (lower voltage recommended).

The flattener, also known as a field flattener, is an essential lens designed to rectify the slight curvature induced by the primary optics, ensuring an even field. This curvature often results in diminished sharpness of stars at the edges of the field of view. By employing the flattener, astrophotographers can capture images where stars retain their sharpness throughout the exposure, providing enhanced visual appeal. 

Crafted for dedicated Astro-Imagers, this premium accessory delivers exceptional performance by effectively reducing the telescope's focal length by a factor of 0.85x while significantly enhancing field-edge correction. Pair it seamlessly with M48 Canon or Nikon T-ring adaptors for optimal compatibility.

The flattener serves as a corrective lens that rectifies the slight curvature induced by the primary optics, ensuring an even field. This curvature often leads to diminished sharpness of stars at the periphery of the field of view. 

The flattener, also known as a field flattener, functions as a lens to eliminate field curvature induced by primary optics. This curvature often results in stars appearing less sharp at the edges of the field of view.

This ED apochromat, compact yet of exceptional quality, delivers impeccably sharp stars for precise tracking, thanks to the ED type S-FPL53 lens element. Focusing is facilitated by a helical fine-pitch thread focuser.

While the original Lodestar utilized the ICX429 Exview chip from Sony, renowned for its exceptional sensitivity, Sony has now upgraded it to the ICX829. This latest 'Exview 2' chip boasts significantly improved Quantum Efficiency (QE) and reduced read noise, effectively doubling the Lodestar's sensitivity and adding nearly a full magnitude to the minimum guide star brightness.

Renowned for their compact designs and exceptional quality, Starlight Xpress continues its legacy with the Trius series. These cooled cameras redefine deep sky photography, boasting improved noise performance while maintaining rapid download speeds of approximately two million pixels per second.

Renowned for compact, innovative designs and exceptional quality, Starlight Xpress continues its tradition with the new Trius series. These cooled cameras redefine deep sky photography, surpassing their predecessors in noise performance while maintaining rapid download speeds of around two million pixels per second.

The guide camera features a 4.9 x 3.7mm (1/3'') CCD chip and is equipped with a 1.25'' sleeve, compatible with CS-mount lenses. Its weight is under 100 grams, ensuring lightweight portability.

The flattener serves as a corrective lens, evening out the field which may be slightly curved by the primary optics. This curvature often results in stars appearing less sharp at the edge of the field of view.

Powermates excel where Barlows reach their limit, offering freedom from aberrations, enhanced magnification capabilities, and a compact form factor.

The optical chain is only as strong as its weakest link. Tele Vue's groundbreaking 82-degree Nagler and 100+ degree Ethos eyepieces set industry standards for the largest, flattest, and best-corrected visual fields. Pairing the Nagler/Ethos revolution with the Dobsonian revolution and Paracorr creates an ideal combination for breathtaking wide and sharp "spacewalk" observing.

Introducing the Signature Series, the next evolution of astronomy cameras, engineered to industrial standards for durability and affordability. Perfectly tailored for lunar, planetary, and solar astrophotography, these cameras boast cutting-edge CMOS technology. Exceptionally light-sensitive and delivering unparalleled image quality, they excel in low-light conditions.

Capture stunning planetary and deep-sky images effortlessly with the Touptek 300KMA camera - your gateway to unparalleled astrophotography. Say goodbye to the frustrations of noisy webcam chips and embrace a new era of clarity and precision in your celestial photography endeavors.

Embark on a journey to master planetary photography with the Touptek 1200KPB, a revolutionary camera designed to elevate your astrophotography experience. Building upon the success of its predecessor, this advanced planetary camera boasts enhanced sensitivity, improved electronics, and a host of features tailored to unleash your creative potential.

Newtonian telescopes are renowned for their superb imaging capabilities, but they can sometimes introduce image distortion, particularly at the edges of the field of view, resulting in star shapes resembling tiny comets—a phenomenon known as coma.

The flattener is a vital component that ensures uniformity in astrophotography by addressing the slight curvature introduced by primary optics. This curvature often results in stars appearing less sharp at the edges of the field of view. Enter the flattener, also known as a field flattener, which effectively corrects this phenomenon, allowing astrophotographers to capture images where stars remain consistently sharp from edge to edge.

The flattener is a crucial optical component designed to rectify field curvature induced by primary optics. This curvature often results in diminished sharpness of stars at the periphery of the field of view. By evening out the field, the flattener—also known as a field flattener—ensures that astrophotographers can capture images with consistently sharp stars right to the edges of their exposures.

The flattener, also known as a field flattener, is a vital lens that rectifies the slight curvature in the field caused by primary optics. This curvature often leads to reduced sharpness of stars at the periphery of the field of view. By evening out this field curvature, the flattener ensures that stars remain consistently sharp throughout the entire exposure.

Designed as a finder, this optic offers an expansive field of view exceeding 5°, providing ample coverage for comprehensive observations. Utilizing eyepieces without crosshairs transforms it into a super wide-angle telescope, ideal for capturing comets, the Milky Way band adorned with star clusters, and diffuse nebulae.
