TS Flexible dew cap can be used universally for Schmidt-Cassegrain telescopes, newtons or even for travelling telescopes, even refractors.
With a flexible impact, weather and aging resistant design, there is a fit for almost any telescope tube. Wide Velcro straps and (foam) rubberized mounting surfaces promise a stable non-slip fit, and the inner felt covering not only keeps out moisture but also light sources that cause reflections from the sides, not only extending viewing time but also increasing the contrast of the image seen/photographed.
Because the dewcap can be placed around the telescope tube when transported, so it does not take up unnecessary space, they are also a good alternative for hiking with removable fixed dewcap tubes.
