I’ll first talk about the mechanics of it. It arrived in a heavy duty bolt case that has "MZT8-24" stamped on it. The finish is nice, the eyecup (always up, you can’t fold it down) is soft rubber, and there is a rubber grip on the

I was struck with aperture fever and I sold that scope in order to purchase a mirror blank and material to make my own telescope. But I kept the good eyepieces. A few months later and my 12 inch reflector saw

I purchased the Vixen LV 50mm in a department store in downtown Osaka, Japan for 12,000 Japanese yen, about US$105.00. I was looking for an affordable low-power eyepiece that would give me a large exit pupil for a Maksutov Cassegrain telescope.

My interest was roused by an ad for the "I3 Piece" image intensifier eyepiece by Collins Electro-Optics. It claims an increase in the light grasp of a telescope by about two magnitudes, or the equivalent of a non-intensified telescope 21/2 times larger. Then there was that positive review of the I3 Piece in the February 1999 Sky & Telescope. I also visited the Collins Electro-Optics web site for more information. The answer to a dilemma appeared to be at hand - more light grasp without more telescope to lug around.

This lens is from the classic Televue Nagler series. It is in the 2 inch format and has a focal length of 17mm. It has an 82 degree apparent field of view that gives incredibly wide views. The lens has a

The TMB92SS with the 31mm Nagler; at 16x and with a 5 degree field, provides one of the most remarkable rich field views obtainable in portable telescopes available today.

Since Cloudy Nights asks that we give a little background on ourselves, I will say a few words here about it. Aside from sporadic childhood observing, I’ve been a serious observer for the last 8 years, being mainly a hunter of deep-sky denizens from dark sites. However I thoroughly enjoy both lunar & planetary observing too, which I perform mostly in my backyard, since the seeing there tends to be quite a bit better than the dark sites I frequent. I currently own 4 telescopes which are a 14.5” f/4.3 Zambuto equipped Starmaster (reviewed elsewhere on this site), a 10” f/5.4 home-made dob with a mirror from Mike Spooner, an 92mm AP f/6.6 Stowaway, and an older version of the WO 80mm f/6 Megrez, not to mention a plethora of eyepieces. I have no affiliation with any astronomy OEM or retailer, although with the amount of money I’ve been throwing at them as of late (to my wife’s consternation), perhaps I should reconsider that position!

I recently acquired a Tele Vue TV102 refractor, and decided I needed some high power eyepieces. I had a Tele Vue Nagler 3-6mm zoom, but was unhappy with what I felt was too narrow a field of view and lack of eye relief. I was considering the 5mm Nagler or Radian, when I saw an ad for the new version of the 5x Powermate. I already had a 2.5x Powermate that I used with my 24mm and 19mm Panoptics with my 8” SCT, and was very happy with it, so I sold the zoom, bought the Powermate, and pocketed the change – temporarily, it turned out.

The following field testing was done comparing the new TAL UWA-24mm ultra-wide eyepiece to the Apogee WideScan II 30mm, and a Meade SWA-24.5. Some comparisons were also made to other eyepieces but were not the subject of this test. Weight of the UWA-24 is the same as 30mm Wide Scan or 40mm MK

TAL 24mm UWA is a high-quality eyepiece for low-power wide-angle scanning of the sky with emphasis on large open clusters such as Beehive, Pleiades, Hiades, Alpha Perseus.

With my recent expedition to NEAF 2009, and the kind offer from fellow CNer “Gary” (Member # 10111) to borrow his 40mm, I found in my possession two very nice (and affordable) 40mm’s to test.

Almost two years ago I got rid of all my 2" telescope eyepieces, and other parts. At the time I had given up on wide field viewing. Although I had started out 40 years ago with refractors, I was now fully converted to reflectors of the Cassegrain type and had settled for the relatively narrow field of view (FOV) they afford. I had recently gone through 3 refractors, one Meade and two Syntas and thought that I would not be able to find one meeting my requirements. Somehow, over the years, I had developed a real dislike of chromatic aberration or false color and both of the Syntas had it. When the last of these refractors left, so did my requirements for 2" eyepieces.

The eyepiece is made from CNC maschined black anadized aluminium body. The lenses are fixed in the upper 1/3 part of the housing surrounded by the movable eyeguard, with which you can search your best eyerelief, changable from 10 mm to 20 mm. The 44.4 mm is the distance from eyelens to focus. With this movable eyeguard you have the possibílity to find the most comfortable eyerelief for yourself. Works similar to the movable eyeguard on the XL 40 mm.

For many of us, a Rodenstock or a Nagler 31 is a little outside our ballpark. Faced with the reality of limited funds, we find there are many remaining choices, but two of the undisputed best commonly available eyepieces in this FL are the Pentax XL 40 and the TV 35 Panoptic. Both are wonderful wide field eyepieces, and both are heavy hitters on the pocketbook.

On daytime targets, the eyepiece seemed to work well with my 120mm f/5 achromatic refractor. The eye relief is given as 28mm and that seemed about right to me. The view didn't

Very well made with chrome lower barrel and black upper piece that has rubber grip ring. Threaded for 2" filters. No eyecup. Lense is set in 5mm approx. Lens edges appear to be darkened. A handsome, high quality looking eyepiece.
