Altair Wave Series 80mm F6 Super ED Triplet APO (80/480)
|
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 over-engineered 3" 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 associated products 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 mount. The 3" focuser is compatible with the Altair-Rigel USB nStep motor focuser for perfect PC automated or manual focusing via the hand controller or USB port.

FREE Protective case with foam padding (note the case is designed to protect the telescope during shipping and is therefore offered as "free". We cannot provide replacement cases if marked or damaged, however the telescope itself is of course fully insured against any damage in transit).
Accessories: We recommend the optional Altair Astro 60mm finder scope (shown in the image) or Altair MiniGuider 60 for autoguiding with this telescope. If you want to start observing and try imaging later, you can order the finder first, and the autoguider adapter later on to convert your finder into a Miniguider. (See associated products below). Please note that this telescope does not come with a finder shoe bracket as in the picture, however there are two holes on the focuser are compatible with most finder scopes.
A separate optional dedicated Planostar 1.0x field flattener for the 80/480 EDT is available for imaging. This screws directly into the focuser, and terminates in an M48 thread, which is compatible with various M48 DSLR and CCD camera adapters. (Please see the associated products tab for more info).
Availability: Please note these telescopes are made in small quantities and are extremely popular. We hope to have our next production available at some time in May 2013.
