Artificial lighting in populated areas brightens the night sky and reduces contrast, making faint deep-sky objects difficult to detect. Skyglow from streetlights and other sources often masks delicate nebular structures. Emission nebulae differ from galaxies, globular clusters and reflection nebulae because they emit light at very specific wavelengths. While the human eye is primarily sensitive to the O-III and H-Beta lines, cameras can record all of these wavelengths, including the deep red emissions of hydrogen and ionised sulphur.

The DSC-0125 is a 1.25" 90° diagonal mirror featuring a 96% reflective aluminum coating.

The TeleVue BIG Paracorr Type 2 is a high-performance coma corrector designed specifically for Newtonian telescopes. In fast Newtonian systems, stars near the edge of the field can appear distorted and comet-shaped—an optical aberration known as coma. This corrector effectively eliminates that distortion, producing sharp, well-defined star images across the entire field of view. This model is engineered for large telescopes equipped with a 3" focuser and is particularly well suited for imaging applications.

The TeleVue Large Field Corrector is designed to deliver perfectly flat image fields for astrophotography with TeleVue NP apochromatic refractors. It is specifically optimized for the NP101, NP101is, and NP127is models. While these telescopes already provide excellent field correction for APS-sized sensors, larger sensor formats such as full-frame require additional correction to maintain sharpness across the entire image. This field corrector ensures precise image field flattening when using large-format camera sensors.

The TeleVue TRF-2008 0.8x Reducer/Flattener is designed to reduce the focal length and simultaneously flatten the image field of compatible refractor telescopes. By shortening the focal length, it widens the field of view and allows for shorter exposure times, making it easier to capture extended nebulae, large galaxies, and wide deep-sky regions. With this reducer, expansive objects such as the Andromeda Galaxy can fit comfortably within the image frame.

The TeleVue 0.8x Reducer/Flattener is designed to improve image sharpness across the entire field by correcting focus away from the center. It reduces the telescope’s focal length to 80% of its original value while simultaneously flattening the image field. This results in a wider field of view and better edge performance, making it ideal for astrophotography with sensors up to 35 mm full-frame format.

The TeleVue Paracorr Tunable Top is an adjustable accessory designed to optimize the performance of TeleVue Paracorr coma correctors. It allows precise positioning of the eyepiece relative to the corrector lens, ensuring maximum coma correction and maintaining sharp star images across the entire field of view.
