  • The TS-Optics M48 Filter Changer - strengthened Design


    Filter Changer with a M48 x 0.75 Connection for Astrophotography and Observing

    Change filters within only a few seconds without having to remove or turn the camera. With only 100 grams (~3.53-ounces) weight and a diameter of 80 mm, this filter quick changer is more compact and lightweight than any filter wheel. The filter changer is an exiting alternative, any filter combination is possible, even the combination of 1.25-inch and 2-inch filters. As a result, the TSFSLM48 filter changer becomes to one of the most versatile accessories on the market.

    The advantages of the TSFSLM48 filter changer at a glance:

    ♦ Due to a strengthened housing and longer M48 threads (male and female), the changer is suitable even for heavy cameras.♦ With only 100 grams and 85 mm diameter, the focuser is almost not burdened, thus filter changing becomes possible even for smaller telescopes.♦ You can use any filters and filter combinations and even change between mounted 1.25" and 2" filters, suitable drawers can be found in the accessory section.♦ Due to only 18 mm length, the changer can easily be combined with most cameras and correctors.

    Application areas of the TS-Optics filter changer:

    ♦ Deep-sky astrophotography: L-RGB images, false color images, contrast enhancement with nebula filters and monochrome or color astro cameras and DSLR♦ Planetary observing and planetary images: quick changing of color filters for enhancing the contrast effect. In photography, the images can be combined well.♦ Deep-sky observing: The impressions without filter, with UHC filter, Oiii filter and other filters can be compared directly. Thus you can always get the maximum of detail out of the object!

    Practical advice from Teleskop-Service:

    ♦ Especially for astrophotography, measurements depend on a fraction of a millimeter. With their M48 tuning rings and extension tubes, you can adapt the filter changer exactly to your "image train".♦ TS recommends one drawer for each filter. Interchanging of filters by screwing into they same drawer during imaging or observing is rather impractical.
