The Altair 150EDF is our largest ED doublet refractor so far, and "big brother" to the mould-breaking Altair 125EDF, another Altair sponsored design now available worldwide.
This is the affordable "dream scope" for many amateur astronomers, and with 6" of aperture it will give simply amazing images through the eyepiece or camera. Whether you are interested in solar imaging, lunar or planetary imaging and observation, or astrophotography with a big aperture for real detail on nebulae and galaxies, this telescope will do it all and then some at a price which is unheard of, for this specification.
The focal ratio of F8 and the FPL53 ED Glass element allows excellent colour correction for high resolution imaging, and visual use. This scope can be considered as "APO" and has carefully controlled spacing between objective elements for excellent performance.
Colour aberration is almost non-existent (not visible at all in focus) and the doublet lens acclimatises quicker to ambient temperatures, reaching optimum performance fast.
Not only are the optics top quality - so is the CNC machined optical tube, Rack and Pinion focuser, tube rings and sliding dew-shield with super-durable powder coated finish.
Each Altair 150EDF refractor comes with an interferometry test report in green light. The test report is logged against the lens serial number, and as usual, always the pick of the best optics when assembling any lens.
Weight is 8kg and length is about 1.2m assembled, allowing another 40cm for the dewshield extended. We recommend the iOptron CEM120 or SkyWatcher EQ8 for imaging and/or visual use, however the EQ6 mount will handle the scope for visual use, and/or solar system imaging.
Please note these telescopes are made to order because optics assembly and testing takes some care and attention - therefore there may be a waiting list. Please get in touch for more information about your order and options for field flattener, reducer, or mounting hardware.
