Tele Vue Nagler 17mm Type IV – The 82° apparent field of view Nagler series started the wide-field eyepiece revolution. But it wasn’t just the ultra-wide apparent field of view that captured the attention of astronomers the world over – itt was the fact that the 82° apparent field was sharp from the centre to the edge – even in fast f/ratio telescopes.
Looking through Nager eyepieces has been dubbed a “spacewalk” experience. Over the years the Nagler has evolved to include 3 series – the Type 4, Type 5 and Type 6.
The Nagler 17mm Type 4 provides long eye-relief. They are the perfect choice is you prefer to wear glasses while observing. Larger eyelenses and a comfortable eyepoint are the trademarks of the Type 4 Naglers.
