The Altair Astro 80mm ED Triplet APO refractor uses a 480mm focal length lens cell with Japanese FPL53 ED glass from Ohara.
A rigid aluminium tube with two tube rings allows stable mounting for astro photography, and the 3.5" rotating dual speed focuser can handle heavy loads, with a direct threaded connection to the optional dedicated Altair 1.0x M48 field flattener (option available in dropdown menu below).
Tube rings are provided with standard M6 hole patterns to fit most hardware mounting systems on the market, and are fully compatible with the Altair TMS Telescope Mounting System TM.
We recommend the Altair Astro 60mm Deluxe Finder Scope (see drop dpwn menu below) which is a perfect fit and can double as an autoguider for imaging by adding the Altair Miniguider adapter.
As a portable wide field refractor for astro imaging or visual use, this is an extremely capable telescope in all areas. Colour correction is excellent, and contrast is very high, enabling faint and subtle details to be observed visually or in images. The optical tube assembly is perfect for the iOptron iEQ30 or iEQ45 mount, Avalon M-UNo and Linear mounts .
The 3.5" focuser is compatible with the Lakeside Motor Focus systemfor perfect PC automated or manual focusing via the hand controller or USB port.
Hand crafted optics: These 80/480 EDT APO optics are hand finished at the final stages of production and repeatedly tested until signed off by the optician in charge. Each lens cell has a unique serial number, guaranteeing it's originality as a genuine limited edition Altair Astro optic. A laser interferogram image in 532nm green light with corresponding lens serial number, is available for an additional £85 at the time of ordering. We need to know in advance if you need a test report.
