AG12 Telescope
The AG Range of precision crafted telescopes
AG12 Telescope
From: £6,474.60 excl. VAT
Our AG12 is by far the most popular model in the AG range of Newtonian Astrographs.
Why is the AG12 so popular? Several reasons, all of them important to customers . . . It’s weight ensures its not too heavy to be used as a portable instrument, it travels incredibly well. No need for an observatory, you can easily position it on your mounting in a minute or so without any assistance. The performance will amaze you, we really mean this, it will amaze you. We have images taken with AG12’s which are often compared (not quite equalled but a very, very respectable offering) with professional telescopes of several metres aperture. Don’t believe us? Email us for some spectacular image links showing comparisons, you will believe us then.
We know why the AG12 is so good and, the amateurs, professionals who now own one, will tell you also. It’s the attention to detail and, the superb optics and their coatings, you won’t beat them, anywhere. AG12 Astroimager Mike Sidonio explains a few things here which might shed a little more light on the subject.
Rather than us explain the merits of an AG12, we will let the images speak for the telescope. Take a look at some of Mike Sidonio’s images in our gallery and Peter Shah’s too, who just had to upgrade as soon as the AG12 was off the production line from his AG8. He knew what the AG8 was capable of and he then realised that the AG12 would be a stunning upgrade, his images are witness to that decision.
Below are all the options available for the AG12. If you feel you would prefer speaking with one of our technical staff on the application and choice of these options prior to ordering, please email us at john@orionoptics.co.uk
