Astromania #ad - The masks grip the telescope tube gently but firmly with three metal posts which have non-scratching silicon sleeves to protect you valued telescope surface. They will never be brittle in the cold, unlike some other masks which are made from normal plastics. This prevents slippage, whilst allowing the mask to remaining perfectly central.
They have adjustment latitude of about 65-100mm, in aperture making them very versatile. Because of this 3-post mounting, the mask remains centered, whilst fitting a wider range of telescopes. Suitable for use on all types of telescope - reflectors, dobsonians, Mak-Cas and SCTs.
