Televue 7mm Nagler T1 new
      #5849719 - 05/09/13 10:32 AM

Soon I will be receiving a Televue 7mm Type-1 Nagler eyepiece. The only other Nagler I ever owned was a 11mm Type-1 which is "long gone" from my current eyepieces. What are your experiences with the Nagler 7mm T1 with short focal length scopes? Thanks.

Jim

Used it (7T1 smoothside & 11T1 only came in smoothside). Love both of them in my 10XTi AND the 102XLT. Haven't tried it on my ST80 (f5), but it works well in my XTi, even without the paracorr, fantastic on Saturn and Jupiter, and DSO's just pop out. Love it! I don't ever see me selling any of my T1s (I have all the T1 smoothsides and love them all, even the 13mmm with its kidneybeaning).

Jim,

It works superbly in a 480mm focal length Tele Vue Ranger.

It also Barlows well in that scope. I have taken it up to 171x, with this configuration, without a breakdown in resolution.

Best way to put it is once you have one, you'll never let it go.......

I bought both 4.8T1 and 7T1 Naglers some 20 years ago but I did not use them much due to my severe addiction to binoviewers, but then a couple of months ago I purchased identical smoothside pairs for both, now I can use both for high power work with my 155 F/9 refractor.
I also have 9T1 in pairs.

The N 7 T1 is a classic. Superb eyepiece. Perhaps the finest of the original T1's. This eyepiece in the smooth-top version, without eye guard, tends to completely disappear, leaving you with a large sharp picture-window floating in space. Enjoy!

You are right. That is the "best way to put it."

Never tried the 7mm but I can never part with my 11mm type 1.

I've used my Nagler 7T1 pretty extensively with my f/6 - f/7.75 refractors, with FLs ranging from 480-790mm, and think of that particular eyepiece as a keeper. It's sharp to the edge and has a nice wide AFOV. IMO its only real drawback is it's relatively short eye relief, but I'm comparing that to my long ER Vixen LVWs and type 4 Naglers. Compared to a Plossl with similar FL, the ER is actually quite comfortable.

Thanks for the replies. My computer crashed & the hard drive ruin. I had to purchase a new one which took me 12 days off of CloudyNights---but I'm back!
Yes the Nagler 7mm T1 is awesome on my scope at 202x. I have used it only once & that was on the Moon,Mizar & Alcor & M-81. On that night the skies were getting a haze from cirrus clouds so I quit after 1/2 hour. The Moon was still unreal at 202x with a 82-degree fov.
