If you’re looking for a set of quality filters, check out the Baader 1.25” LRGB CCD Filter Set. It includes a luminance, red, green, and blue filter with ultra steep cutoffs and a high transmission rate of more than 95%. Each filter has also been treated with anti-reflection coatings that maintain the sharpness and contrast of the image. The set is also available for 2” eyepieces.

That infrared radiation -that comes from a LED-emitter- has a wavelength of 940 nm (nanometres), which is too high to be seen with the naked eye. This means that whatever is being observed won’t be disturbed by the HikMicro 940 Nm IR Illuminator. The infrared radiation has a range of 200 metres.

This infrared illuminator has a weight of 95 grams, which means you can hold it in your hand just fine or you can use a mount to attach it to a night vision scope. It has an operating time of 5,5 hours on a fully charged HM-3633DC battery, which can be purchased separately.

Feel free to contact one of our telescope experts for advice on selecting the filter assortment that is right for you.

One of the most crucial accessories of astro-imaging is filters. Eyepiece filters are an invaluable aid in lunar and planetary observing. They reduce glare and light scattering, increase contrast through selective filtration, increase definition and resolution, reduce irradiation, and lessen eye fatigue. Different filters will act differently, highlighting a rainbow of wavelengths to enhance a variety of features in the night sky.

Deep-space imaging in particular benefits from filters. Far away celestial objects, such as nebulae come to life in your photos with vivid colors. We recommend starting out with an h-alpha filter to filter out broadband light pollution while only allowing a very narrow bandwidth of light to pass through. These are a favorite filter among astrophotographers!

For example, the Baader 35 nm Midband H-Alpha CCD Filter fits 1.25” eyepieces and produces high-contrast images of H II regions. Featuring scratch and moisture resistant coatings, it’s the perfect choice for imaging faint nebulae from light polluted observing sites. This filter is also available for 2” eyepieces.

This HikMicro 940 Nm IR Illuminator can be used in conjunction with a night vision scope. Scopes with night vision functionality amplify residual light in order to depict a clear and understandable image, which would be much harder to see with the naked eye. If there is absolutely no residual light, if the moon and stars are obscured by clouds for instance, this IR illuminator can be incredibly useful. It emits infrared radiation in whatever direction you point the illuminator in, which can be seen with the night vision scope.
