This stray light protection, often affectionately referred to as a “sock,” prevents unwanted light from entering a truss-tube Dobsonian telescope.

IDAS Night Glow & LPS Filters improve the contrast of astronomical emission nebulae against skies affected by both artificial and natural sky glow, while maintaining accurate color balance for broadband objects such as galaxies. Like other IDAS interference filters, the bandpass design accommodates the steep light angles produced by fast optical systems.

This narrowband line filter is designed for astrophotography, specifically to enhance the visibility of emission nebulae by isolating key oxygen emission lines. By suppressing unwanted background light, it increases contrast and reveals fine structural details in nebulae. The filter is optimized for imaging rather than visual observing and is best suited for deep-sky photography under light-polluted or dark-sky conditions.

This H-alpha filter transmits light at a wavelength of 656 nm, making it an excellent choice for narrowband astrophotography. It delivers high-contrast images and reveals fine nebular details, even when imaging from locations affected by strong light pollution.

The SII narrowband filter is designed for nebula astrophotography and transmits light centered at a wavelength of 672 nm. With a narrow bandpass, it enhances contrast and isolates sulfur emission, making it well suited for imaging emission nebulae, planetary nebulae, and supernova remnants. For astrophotographers seeking the classic Hubble Space Telescope–style appearance, such as the iconic “Pillars of Creation” in the Eagle Nebula (Messier 16), the SII filter is a natural addition after H-alpha and OIII filters. Like H-alpha, SII operates in the deep red region of the spectrum near 672 nm.

PoleMaster is a high-precision, easy-to-use electronic polar alignment scope designed to make accurate polar alignment fast and straightforward. Achieving precise alignment can otherwise take a long time, and even a small bump to the mount can force you to start over. While mounts such as iOptron’s center-balanced equatorial models allow quicker alignment through built-in polar scopes, they still require awkward positioning and physical effort during setup. The most direct method of polar alignment is to locate the true north point and match it with the rotation center of the right ascension axis.

This compact star tracker is designed as a powerful yet ultra-portable solution for DSLR cameras, weighing just 720 grams while smoothly tracking camera and lens combinations of up to 4 kg. Its impressive performance is made possible by modern strain wave gear technology, an area in which iOptron pioneered industry-standard applications for astronomical mounts. That experience is now built into this remarkably small device.

The MiniPier has a compact and sturdy design, measuring 15 cm in height with a diameter of 25 mm and a total weight of 0.5 kg (1.1 lb), making it easy to transport while providing solid support.

This precision-adjustable equatorial base is designed for use with SkyHunter, SkyGuider Pro, and SkyTracker Pro mounts, providing accurate polar alignment for astrophotography and tracking applications. A built-in bubble level helps ensure proper setup, while the Vixen-style dovetail saddle allows secure mounting of compatible equipment. The base offers a wide altitude adjustment range from 0° to 90°, making it suitable for use at any latitude.
