Optolong UV/IR Cut 1.25" Filter Mounted (O... $57.95
Optolong UV/IR Cut filter is designed for ultraviolet and infrared wavelength blocking to improve sharpness of the image as most of the optics are designed for the visible spectrum, because it’s very difficult to create a lens with the same focal point for the visible and IR spectrum. Description It is used on a digital camera and the video, which do not have an IR protection filter toward an image sensor or were remodelled. This is important because unfiltered CCD and CMOS sensors are extremely susceptible to UV and IR rays just outside the visible spectrum that can have a...

Astronomik
Astronomik 1.25"/2" L-3 Luminance UV/IR Bl... from $119.95
The Luminance channel is probably the most important for a great final image! You want as much signal as possible so the filter should have the highest transmission possible with a wide spectral bandpass. This combination provides the greatest sensitivity and gives you the highest photon counts on your pixels. While the high transmission level is a great aspect of the new Astronomik Luminance filters, not all optical instruments or additional optical elements like correctors, field-flatteners or reducers, have perfect colour correction so it can be the width of the spectral band pass of the Luminance filter that can cause...

Baader Planetarium Contrast Booster Filter... from $119.99
Discover your telescope anew – with the Baader Contrast Booster: Planeoptically Polished and Phantom Group Coated Description A unique filter for many different astronomical tasks – incomparable in acuity to combinations of generic colour filters, made of raw polished glass – where surface inaccuracy adds up in the optical wave front to an unbearable degree. Especially designed to improve the beginners telescopes – to provide a professional replacement for the simple "dark green" Moon & Solar-Filters made of "raw polished" glass. Note: For Solar Observation use only in combination with Baader AstroSolar Safety Film! The Transmission Line Of Baader Contrast...

Optolong Planetary filters Kit (UV/IR Cut,... from $349.99
Optolong Planetary filters kit including UV/IR Cut, R, G, B and IR685 filter, 5pcs filters in total. These five filters are boundled by "Solar System Seal". Main Use UPhotography of planets and deepsky imaging, both are fine to use the combination of monocrom camera and filters. But slightly different, planets photography will not use what deepsky image use like Ha, SII, OIII filter. Planetary photography using filters often are IR, UV,filters, etc. The main aim is to capture the specific spectrum, such as rich carbon dioxide. One of the most commoon filter we use is IR filter- infrared filter. In...
