Askar Flattener 1.0x 103APO (86169)
252.01 $
Tax included
A field flattener is an optical lens designed to correct the slight curvature of the image field produced by a telescope’s primary optics. This natural curvature causes stars near the edges of the field of view to appear less sharp. By correcting this effect, the flattener ensures that stars remain sharp and well-defined across the entire image, from center to edge.

471.95 $
Tax included
Astronomik XT filters for wide-angle optics are designed to deliver sharp, well-defined stars right into the corners of the image, even with extreme wide-angle lenses. With standard Astronomik filters, image quality at very short focal lengths can be limited. Although these filters use a glass substrate only one millimetre thick, certain wide-angle lenses can still introduce aberrations, causing stars near the edges of the frame to stretch into short lines.

Hotech 2" SCA field flattener (22937)
Hotech 2" SCA field flattener (22937)
280.11 $
Tax included
Refractor telescopes often produce optical errors toward the edge of the image field. This leads to field curvature, where stars near the edges appear blurred, distorted, or out of focus. Such curvature reduces image quality and is especially undesirable in astrophotography, where visual aesthetics and pinpoint stars matter. The Hotech Field Flattener offers a simple and effective solution to this common issue. Achieving sharp stars right to the corners of the image is possible with the Hotech Field Flattener—and it is remarkably easy to use.

Artificial lighting from cities and towns brightens the night sky and reduces contrast, making faint celestial objects harder to observe. While streetlights improve visibility on the ground, they create skyglow that obscures delicate deep-sky structures. Emission nebulae differ from star clusters, galaxies and reflection nebulae because they radiate light at very specific wavelengths. Instead of producing a broad spectrum, they emit distinct spectral lines.

Artificial lighting in urban and suburban areas brightens the night sky and reduces contrast, making faint deep-sky objects more difficult to observe. Skyglow caused by streetlights and industrial lighting often overwhelms delicate nebular structures. Unlike galaxies, globular clusters or reflection nebulae, emission nebulae radiate light at specific wavelengths. Because the human eye has limited sensitivity in the red spectrum, only the O-III and H-Beta lines are easily visible visually. Cameras, however, can record all these wavelengths, including the deeper red emissions.
