Bahtinov masks take the guesswork out of focusing and even get over the seeing conditions as it is a mathematical type approach to the task.The best focus for your telescope quickly and easily.
Suitable for use on all types of telescope - reflectors, rafractors, Dobsonians, Mak-Cas and SCTs. They are made from precision laser cut enforced plexiglass, which is stiff and long lasting. They will never be brittle in the cold, unlike some other masks which are made from normal plastics.
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. This prevents slippage, whilst allowing the mask to remaining perfectly central. Because of this 3-post mounting, the mask remains centered, whilst fitting a wider range of telescopes.
They are made from 2mm thick laser cut plexiglass and the securing screws are capped with soft plastic so that they do not damage your telescope.These high quality Bahtinov masks are adjustable to fit a wide range of optical tubes, unlike masks which are only able to fit one telescope. They have adjustment latitude of about 65-100mm, depending on model, in aperture making them very versatile.
Please be assured that these focusing masks will work excellently for both reflectors and refractors with whatever focal length. All you need to do is to measure your telescope tube size and choose the right size of the mask (contact us if you are not sure where to measure).

Corrected field curvature for the best observing: Premium flat field eyepieces offer corrected field curvature, normally one of the flaws in optical imaging. This correction lets you use the entire field of view. You will observe an image with superior sharpness - not just in the centre, but right out to the outer edge. These eyepieces let you observe natural objects just as they appear in reality.
Multi-coating and crystal-clear images: The large eye lenses will impress you at your very first glance at these eyepieces. The crystal-clear images you then see when looking through the eyepiece will then impress you even more. The high quality of the 5-6 lens elements and the high light transmission give you an image of high colour purity and excellent contrast.
Twist-up eyecups: The eyepieces have solid and infinitely adjustable eyecups, making it easy for you to choose your most comfortable viewing distance - ideal for long intensive observing sessions. The various models have focal lengths of 8mm, 19mm and 27mm and are also ideal for spectacle wearers.
Wide field of view - between 58° and 65°: What does an extended astronomical object look like through the eyepiece, as compared to a standard Kellner or Ploessl? Imagine you are observing the Lagoon Nebula with an 8" f5 Newtonian telescope: While in the standard eyepieces the object extends well beyond the field of view, any of these wide angle eyepieces (around 19mm) will show you the entire object. This is because these eyepieces offer 20-30% larger fields of view than a standard eyepiece.
Look great and last a lifetime with their anodized housings: These premium flat field eyepieces also look classy - the entire housing is anodized aluminium. This makes the material particularly resistant and durable. A rubber coating also provides you with a handy grip.
