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 105-150mm, 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).

The new Astromania Off Axis Guider is the lowest profile off axis guider that we know. Despite this no compromise has been made with the function and operating comfort of this versatile Off Axis Guider. mechanical flexure between main and guiding telescope can possibly ruin the tracking accuracy if you use an off axis guider. | 1) Can be used with correctors & DSLR: The only Off Axis Guider that can be used between a coma corrector (or field flattener) and a DSLR camera without leaving the tolerance for the distance between camera and corrector. 2) Can be used with cooled CCD cameras: The off axis guider provides enough space for filter wheels or filter drawers when using cooled CCD cameras. | Place the OAG behind the corrector: The Astromania OAG is used between the corrector and the camera. Using an off axis guider in front of the corrector is not useful. The guide star would be distorted, the distances on both optical paths are too different and you might even get focusing problems with the main camera. Behind the corrector you can avoid these problems, but this only works due to he low profile of the Astromania OAG! | Large Clear Aperture: Compared with many simpler guiders the Astromania OAG not only has a shorter overall length, but also a larger clear aperture. A "T2 keyhole" can be avoided, resulting in better illumination for large sensor cameras up to 45mm diagonal.The load for the mount is much reduced. There is no need for a guide scope and the setup will remain more compact. You work with the main telescope's resolution and focal length, not with the typically lower resolution of a guide scope. | The Off-Axis Guider comes complete with the adapter required for a 2" focuser. If no autoguider, but rather a reticle, is to be connected, then this Adapter or this Adapter is required. We also have T2-rings in our product range for optical path compensation. Depending on the length required, they are: 7.5mm, 10mm, 15mm and 40mm.
