The Ultra High Contrast (UHC) broadband filter is designed to enhance the visibility of a wide range of deep sky objects by reducing the transmission of wavelengths associated with light pollution. It specifically targets and suppresses light from artificial sources such as mercury and sodium vapor lamps, as well as the general sky glow effect. At the same time, the filter remains highly transparent to the main emission lines of nebulae, including OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm), and SII (672nm).

The Ultra High Contrast (UHC) broadband filter is designed to enhance the visibility of various deep sky objects by selectively reducing the transmission of wavelengths associated with light pollution. It effectively blocks unwanted light from artificial sources such as mercury and sodium vapor lamps, as well as the general sky glow, while remaining highly transparent to the main emission lines of nebulae, including OIII (496nm and 500nm), H-beta (486nm), NII (654nm and 658nm), H-alpha (656nm), and SII (672nm).

The Optolong L-Para 2" filter is a dual narrowband light pollution filter designed to significantly enhance astrophotography, especially in environments affected by urban or suburban light pollution. It is optimized for both standard and fast optical systems, including setups with focal ratios as low as F2, making it compatible with a wide range of telescopes and imaging trains. The filter isolates the key emission lines of nebulae-OIII at 500.7 nm and H-alpha at 656.3 nm-each with a narrow 10 nm bandwidth.

The Optolong L-eXtreme filter is a dual 7nm bandpass filter designed for astrophotography with one-shot color cameras such as DSLRs, as well as with monochrome CCD cameras. It is particularly well-suited for fast optical systems and offers an affordable solution for amateur astronomers who want to capture rich images of emission nebulae, even under bright, light-polluted skies.

The OIII Filter: This narrowband OIII 3nm filter is specifically crafted for observing nebulae. It allows a 3nm bandwidth of light centered on a wavelength of 500nm, corresponding to OIII emission lines, while effectively blocking out all other light.

The H-alpha filter, renowned for its narrowband capabilities, specifically targets light in the red wavelength at 656nm. By allowing only the narrow range of hydrogen-alpha light to pass through while blocking unwanted wavelengths, this filter unveils hidden details within hydrogen nebulae.

The H-alpha filter is designed to pass light at the 656nm wavelength, making it an excellent choice for narrowband astrophotography. It is ideal for capturing high-contrast images and revealing intricate details within nebulae, even in locations affected by significant light pollution. The filter allows a narrow 7nm bandwidth centered on 656nm, effectively blocking unwanted wavelengths produced by artificial lighting such as mercury vapor and sodium vapor lamps, as well as natural skyglow caused by neutral oxygen emission in the atmosphere.

The H-alpha filter selectively transmits light at a wavelength of 656nm, making it the premier choice for narrowband H-alpha astrophotography.

SII Filter: Designed specifically for nebula photography, the narrowband S-II 7nm filter selectively transmits light at a wavelength of 672nm, featuring a bandpass of 3nm.

Narrowband filters enhance contrast by selectively permitting specific light wavelengths, such as those corresponding to hydrogen (H-alpha at 656nm), oxygen (OIII at 501nm), sulfur (SII at 672nm), and more, to pass through while blocking others.

Narrowband filters enhance contrast by permitting only specific light wavelengths corresponding to certain spectral lines, such as hydrogen (H-alpha at 656nm), oxygen (OIII at 501nm), sulfur (SII at 672nm), among others.

An off-axis guider is a practical tool for astrophotographers, making it easier to guide your telescope during long-exposure imaging sessions. Instead of attaching a bulky and heavy guide scope, you can use this compact and lightweight device, which is especially helpful for smaller telescopes or mounts with limited load capacity. The off-axis guider slots directly into a 2-inch focuser and features a standard T2 thread on the camera side, making camera attachment straightforward-just add a compatible T-ring for your DSLR and you’re ready to go.

The PegasusAstro FlatMaster is an electroluminescent flat field panel designed to provide a uniform and consistent light source for astrophotography and photometric imaging. It is ideal for capturing high-quality flat field frames, which are essential for correcting uneven field illumination and dust shadows in astronomical images. The FlatMaster stands out for its adjustable brightness, allowing users to fine-tune the illumination for different filters and setups.
