    Outline
    All A&M refracting telescopes are manufactured using carbon graphite and aluminum tubes. Each optical tube assembly (OTA) is CNC machined to the highest tolerances and is computer optimizing for lightweight operation with structural rigidity.

    The front & rear rings and all small parts are fully CNC machined from aluminum, stainless steel or brass. Other features include three point collimation and computer optimized ray traced baffles. The finish of all parts is anodized or multi-coat painted.

    The 4" Dual-speed focuser.
    Optical Performance
    The A&M APOs are based on A&M/TMB lenses that consist of three air-spaced elements. The optics are fully multicoated with APO chromatic correction. Each telescope comes with an inferometric test report included in the price.

    Baffles.
    Internal baffles.

    Within the amateur community astronomical optics performance for both mirrors and lenses is generally expressed in Peak to Valley (PV) terms, this method is not representative of the quality of an optic and as such more accurate criteria need to be employed. To demonstrate the flaw of the PV method of measurement consider the exaggerated image of the profile of two theoretical mirrors at the same 1/8 PV. The mirror on the left will produce inferior images when compared to the mirror on the right.

    PtV.
    In the professional world of astronomy optics the Strehl ratio is in regular use. The Strehl ratio is a measure of optical performance rather than an expression of the physical surface or the shape of the optic’s wavefront as obtained with PV or Root Mean Square (RMS) methods.

    A&M 105mm
    A&M 105mm model with 4" William Optics focuser.

    Strehl performance is measured between 1 and 0, where 1 represents perfect optics. High quality telescopes will generally have Strehl ratios of 0.95 or above. Interferometric testing is required to ascertain the real quality and performance of a mirror or lens in terms of their Strehl ratio. A&M telescopes come with individual interferometric reports (where stated) to guarantee the quality and performance of the optics that you acquire.

    Focuser And Colour Options
    The A&M refractors are fitted with a 3" or 3.5" Feather Touch focusers. Optionally, models fitted with 4" William Optics focusers or MoonLite focusers are also available.

    The telescopes are available in a number of colours including: perl, silver, gold/orange, red and blue. Please state your preference with the order.
