Re: [APML] Up-Scale eyepieces

Hi Glenn -

I picked up a 22mm Type 4 Nagler late last year. The few times I've used it, I've been in awe. It is a wonderful eyepiece.... I guess it should be for $460..... :-o The 31mm Nagler is also suppose to be a killer piece of glass.

I also have the 3, 6 and 18mm Radians for lunar and planetary work. There have been reports of some lateral color with these eyepieces, I have noticed this but it does not bother as much as others. The 20mm of eye relief in a 3mm ocular is a refreshing experience for someone that wears glasses at the eyepiece. I think there is a line of Tak eyepieces that are also 20mm of ER throughout the series but I can't remember the name of them.

Subject: [APML] Up-Scale eyepieces

Though this is a list on astrophotography, we have to frame up our pictures and glimpse the telescopic sky scene before putting in the inevitable CCD autoguider! I suspect that these moments of looking at the stars while out trying to photograph the stars are among the most pleasurable of all for us in this hobby. In this regard, what eyepieces serve the best?

In particular, on this question, one can spend quite a lot on quality occulars. At the recommendation of Jon Kolb I purchased a Takahashi 5 mm focal length occular with LED-illuminated reticle for guiding purposes. This was expensive!! But it's worth it: the occular has excellent resulution to the edge of the field, good eye relief and fine mechanical quality throughout, especially in the engraving of the reticle.

Nagler-type eyepieces are judged to be good quality, so I hear, and those that have attempted to copy Nagler eyepieces have sometimes fallen on their faces, so I hear from the grapevine.

Do any of you have eyepieces that you are especially fond of?
