  • M48 Thin Profile Filter Changer
  • 1x TSFES2 filter drawer for 2" filters

Product Details

  • Change filters within a few seconds without removing the camera or eyepiece. Try different filter combinations for the ideal photographic or visual result. The TS filter drawers are suitable even for compact telescopes with small focusers. With only 85 grams, the quick changer weighs significantly less than a filter wheel, and with only 15 mm length, you will reach focus with nearly all telescopes.

    The M48x0.75 mm connection threads offer full aperture. We suggest this changer for fast telescopes and bigger camera sensors.

    The advantages of the Filter Quick Changer

    • There is no limit to the number of different filters you can use. No laborious changeover is necessary, in opposite to a filter wheel.
    • With only 85 grams weight, the quick changer can be used even with telescopes which are not suited for heavy filter changers.
    • Significantly more compact than a filter wheel or a filter slider.
    • Only 15 mm short, that is not possible with a filter wheel - ideal for telescopes with little back-focus, like Newtonian telescopes, and optimal for combining with correctors and reducer systems for astrophotography.
    • The filters always have the perfect orientation to the optical axis. Neither tilting nor lateral displacement is possible.
    • Easy adaption of accessories through standard thread at telescope and eyepiece side.
    • The filters are carefully stored in the optional protective case and are always freely accessible in the event that dust has to be removed.
    • The ultra low profile results in best possible field illumination. The filter can be used very close to the camera sensor.

    Examples of use

    • Astro imaging: LRGB color imaging, narrowband color imaging, use of different contrast filters and nebula filters
    • Planet observing: Ideal for using color filters. The quick change between the filters allows you to directly compare the effect of different filters and thus choose the ideal filter for the particular application.
    • Deep sky observing: You can directly compare the impressions with UHC filters, O-III filters and other filters. This allows you to get the most detail out of each object!

    Practical advice from Teleskop Service:

    It's recommend one drawer for each filter. Interchanging of filters during by screwing while photographing or observing is rather nonfunctional. 

    If you use a 2" filter, you can make screwing in easier. The problem: The drawer is only slightly bigger than the filter, so it is almost unreachable with the fingers. The solution:

    • Use a 2" barrel (of an eyepiece or adapter).
    • Fix it to the filter by using a little bit of adhesive tape. The male M48 thread has to be free.
    • Now screw the filter carefully into the drawer, using the 2" barrel as extension knob.

    Parts don’t fit

    The filter drawer is fine but the threaded tube extends too far into the drawer box and presses against the drawer. the drawer cannot be removed without unscrewing the tube and is a major design flaw.
