- Canon Ra
- field of view
Had a great experience shopping here. Ron was an immense help and the Priorty shipping was quite a surprise. I received the item in pristine condition and it performs flawlessly. I will gladly do business here again.
I needed a wider field of view because I got a new full-frame camera (Canon Ra). This does the trick; images are brighter, flatter, and less vignetted than a 1.25" powermate or barlow. Just about every store had this back ordered, but good old OPT had it and shipped it immediately.
Worth every dollar Just like my title says a little expensive but very high-quality if you want the best
As Expected from Tele Vue
The 2.0x 2-inch Powermate increases scope focal length and power by a factor of 2. I have used it with the Celestron EdgeHD 1100 for planet viewing and with the ***** 8-inch reflector for globular cluster photography. The Canon T-Ring option is very handy and allows the Canon DSLR to directly attach for prime focal plane photography. The parfocal feature of this optic allows minimal refocusing of eyepieces with or without it in the beam path. Photographs of Jupiter show no obvious spectrum divergence (no red or blue fringes), and no vignetting which are common with the standard Barlow. The image is clear and free of distortion.This piece is excellent and I highly recommend it.
muy buen servicio, lo recomiendo.
