The filter film
The Thousand Oaks SolarLite filter film has a high optical quality and is easily to change if damaged. Usually, it is more robust than a glass filter that can break.

The mounting
The scure fixation of the solar filter on the front end of tube or dew shield will be done with 4 jacketed threaded columns made from polyamide with precisely adjustable clamping. The standard sizes will normally be attached outside on the dewcap, but you can also attach it inside with a minimum of vignetting.

The standard sizes 1 and 2 are cutted to enable the using with binoculars (you need 2 pieces). The objective distance than had to be minimum 65 mm or 78 mm.

The solar filter will be mounted without any seal on the front side plan to the tube or dew shield. Contrary to possible concerns with this construction you won´t have any scattered light. The contrast only will be weakened if intentionally a gap of minimum 4 mm will be done!
