It is 5-Position 1.25" Filter Wheel For Telecope. and high-quality telescope filter wheel allows you to quickly and easily change.A huge time-saver for filtered planetary and lunar observation using different color filters, or for tri-color astrophotography pursuits. Included 5-Position 1.25" Filter Wheel lets you install all filters and then dial-in the 1.25" filter you want to use for a particular astrophotographic exposure. The filters can be changed very quickly at any time.

The robustly constructed filter wheel is supplied with a 1.25" eyepiece adaptor, 1.25" focuser nosepiece, T-2 camera adaptor and locking ring. The filter wheel can be attached to your focuser either by the supplied 1.25" nosepiece adaptor or via a T-thread. It is ideally suitable for visual observations with 1.25" eyepieces. and with the included T2 adapter it is also perfectly suitable for astrophotography with single lens reflex cameras and CCD cameras.

Keep in mind that use of the Multiple Filter Wheel requires 23mm of inward focus travel. This will not be a problem for most telescope designs, but could be a problem for Newtonian reflectors. The included T2 adapter comes with a locking ring, whereby high-precision distance regulation becomes possible.Its very sturdy aluminum housing makes it also suitable for heavy cameras.

Handy color planetary telescope eyepiece filters help enhance your view of the planets and Moon, unveiling specific features and enabling you to discern more detail

High-grade Schott optical glass is vat-dyed for even color coating, then anti-reflection coated for maximum light throughput

Anodized aluminum cells are double-threaded to permit filter stacking for multiple filter use

【Light-Pollution-Reduction UHC Filter】 This ultra-high contrast filter selectively allows emission lines from nebulae to pass through while blocking a large amount of light pollution due to the excessive use of artificial outdoor light

【Improved Contrast】 The filter darkens the sky background and improves the contrast of your images so you can clearly view planetary nebulae and most emission nebulae under a dark sky even when you live in a light-polluted area

【Celestial Observation & Astrophotography】 The filter helps deliver sharp images—an ideal telescope accessory for both night sky observers and astrophotographers

Three neutral Density (ND) Filters with different levels of light transmission (13%, 25%, and 50%) allow you to choose the perfect filter for your viewing conditions

Moon & Sky glow filter provides high contrast views of the lunar surface and enhances observation of deep sky objects from light Polluted Skies

Aluminum filter cells provide a rigid, durable housing for the filter glass and are threaded on top and bottom for stacking

A must-have to safely observe without damaging your eyes - optical filter fits snugly over your telescope's aperture to block 99.9% of incoming light.

This filter features an inside diameter of 75mm - it is designed to fit optical tubes with an outer diameter of 70mm to 92mm,the outer diameter of filter is 100mm.

The filter meets ISO 12312-2: 2015 and Amazon has verified the security. Baader Astro film in a sturdy aluminum cell.

The Variable Polarizing eyepiece filter acts like a dimmer switch for your telescope

Finer control of the image brightness compared to a standard fixed-transmission telescope eyepiece filter for optimal performance

Adjust the amount of light transmission from 1% to 40% by rotating the eyepiece filter housing

IR filter blocks ultraviolet (UV) and infrared (IR) light wavelengths for higher contrast CCD images

Advanced coatings applied to the precision polished optical glass minimize in-band reflections

The 1.25" anodized aluminum cell threads into the nosepiece of an astrophotography camera or filter wheel

Take your astrophotography to the next level with this filter. All filters in the set block ultraviolet (UV) and infrared (IR) wavelengths for higher contrast CCD images.

The ASTROMANIA LRGB Filter Set includes four filters, 2" luminance Filter, 2" Red Filter, 2" Green Filter 2" Blue Filter. This LRGB filter set allows you to use your monochrome CCD camera to put together high resolution colour images.

Combining separate images taken through these filters produces finer resolution and amazing color. Red, blue, and green filters plus the haze-eliminating Luminance filter give you stunning results.
