♦ The BAADER filter foil is clamped plan between two aluminium rings
♦ For visual and photographic use
♦ Variable adjustable clamping on the tube
♦ Made for all telescope types including viewfinder and binoculars except Schiefspieglers

The Filter Film:

The BAADER filter foil has an excellent optical quality and is easily to change if damaged. Usually, it is more robust than a glass filter that can break.

Delivering will include the standard filter foil with a density of ND5 for visual and photographic use.

The scure fixation of the solar filter on the front end of tube or dew cap 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 dewcap. 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!
