My TV 17mm Nagler T4 for your 3-6mm Nagler Zoom.
Is anyone interested in such a trade? My 17mm Nagler T4 is in excellent condition, with flawless optics. It has the usual tiny set screw marks around the barrel, and a few miniscule scratches in the black anodizing. Both end caps are included, of course. The original box is long gone, though. I treat this thing like a Faberge egg!
The 17mm T4 is all it's cracked up to be. In both my 8" f/5 Spooner/Glasstronomic Newtonian, and my 6" f/8 Achromat/Chromacor the wide field combined with decent power is breathtaking. I want to trade because planetary observing has become my passion, and 17mm is more suited to deep sky, when used with my <1200mm FL main instruments.
Please check out my feedback, and let me know if you'd like to trade.
