I MUST use glasses for viewing in order to get the most detail possible, so eye relief is hugely important for me

Have you been looking for a quality wide field eyepiece for under $100?

Since I recently bought a 14" Dob, it had become obvious that I started a quest to search for a good wide-field eyepiece around 30mm

Even though I could not find any reviews of it on the web, in the end I just couldn’t resist the crazy low price of the Moonfish 15mm. I ordered the eyepiece direct from the company’s website

I needed to fill the gap between a 22mm Panoptic and 13mm Nagler, and I was interested to see whether a 16mm TMB would be suitable for observing deep sky objects. I also anticipated using this SuperMono with a 2x Skywatcher APO Barlow lens to view Jupiter on nights of less than perfect

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

The original non-eyecupped version of the 14mm Ultra Wide Angle eyepiece looked massive and impressive (body size: 63.5mm x 130mm, precise weight: 0.67kg) while sitting atop the little Brandon 94mm, f/6.8 apochromatic refractor telescope. The Meade eyepiece, with its closely approximated 82 degree afov (apparent field of view), offered considerably more openness and vastness with an image "feel" than was provided by a 12mm Nagler T2 (body size: 56mm x 114mm, approx. weight: 0.40kg, and closely approximated 80 degree afov), or a 7mm Nikon WA (body size: 42mm x 99mm, approx. weight:0.16kg, and closely approximated 70 degree afov), used in direct comparisons. Please note, this 7mm Nikon eyepiece is the same one formerly referred to as an 8.7mm 72 degree wide-angle. It is the Fieldscope 60x Wide model and is ready made for astronomical use by APM Markus Ludes, a supplier in Germany. The general evaluations were done in a rural town (pop. 6000) neighborhood under excellent transparent night skies with quarter phase moonlight. The seeing was average and fine for the tasks at hand.

The legendary batting instrument, the Brandon 94mm f-6.9 APO, was brought out under transparent (but stable) skies on November 13, 2000 at 9pm CT for the game. Ambient temperature was about 43 deg F. There was an on again, off again breeze enough to cause eye tearing in most any players eyes. It was the first real opportunity to run the bases with the above eyepieces, albeit briefly, but with sufficient levels of scrutiny to judge them fairly. The chosen methods of comparison were hardly the only or best possible ones available for refining results over eyepiece distinctions. Then again, the setting was such to accomplish something with several of them at once, a team! ...without going into overtime (approx. game time was 45

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!

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.

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.

Ever since I bought my NexStar 11 GPS two years ago, I've been searching for ways to get the widest non-vignetted field of view possible from my scope. (Note: When I bought my NS11 I purchased an EyeOpener 2" visual back in anticipation of someday buying large 2" eyepieces. More about that later on).

This is a review of the 14mm Pentax SMC XL eyepiece I won for a review contest on Cloudynights. I remember how happy I was (and still am! thanks Cloudynights!) when I won the contest, so it would only be fair to write a short review on this great eyepiece. Keep in mind that while I have seen a lot of views through different eyepieces (and telescopes), none were in the price range of the Pentax XL. I live in Zagreb, Croatia, and have met many croatian amateur astronomers and astronomy society members, but $200+ eyepieces seem just too expensive for us. There may be some similar eyepieces out there but I've not met their owners (yet). I've only had a brief chance to compare it to my friend's 13.8mm Meade SWA. Not long after the Pentax arrived, I got a new telescope. An Intes MN-71, 7" mak-newt on HEQ-5 mount replaced

June 2000. Los Angeles, CA USA. I've been giant binocular viewing for several years. I purchased my first telescope in the past six months. I now have a Tele Vue Pronto, a Tele Vue 101, and a back ordered Mak. I live in Los Angeles and view primarily from my home in the city. I try to attend the monthly Los Angeles Astronomical Society's dark sky parties at Mt. Pinos. I became interested in the Collins I3 Piece as a tool to use in Los Angeles' light pollution.

The popularity of wide-field eyepieces has surged in recent years, and, to a certain extent, so has their cost and complexity. Systems containing more than the usual handful of elements are required to achieve good correction of aberrations over wider fields especially in the shorter f/ratio telescopes we see today. It was with some trepidation that I heard of the new Wide Scan Type III eyepiece. I tried one and decided that, for its cost, it might have a place in my eyepiece box.

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.

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.

I ordered these from Hardin Optical’s Web site on a Sunday. I received a confirmation and a UPS shipping notification on Monday. The EP’s arrived on Wednesday. Painless and efficient. They were each packed in a plastic bag inside a quality box , and placed in a small box packed with Styrofoam peanuts. The EP’s came with bottom dust caps

People are always looking to improve their equipment choices. Sometimes it turns out that improving choices doesn’t necessarily mean costing more. I often watch to see what second hand eyepieces are for sale. I’ve bought many second hand eyepieces, including two used in this comparison. The Televue 20mm plossl comes up for sale a lot. That’s because it comes standard with Tv scopes and most people have already filled that 20mm niche by the time they get around to buying a Tv scope. So they keep the scope and sell the eyepiece. I bought one second hand and after using it in several of my scopes, including my f8 6" refractor and my f11 5" SCT, I started comparing the view to several of my other eyepieces in the same magnification range. I set out to compare eyepieces from 16mm to 20mm, all mid-priced or low priced inexpensive eyepieces. By inexpensive, I mean not in the cost range of the Naglers, Radians, Ultrawides or even the less costly Superwides.

When I purchased my NexStar 5 a while back, I needed some eyepieces to fill some gaps in my collection. Specifically, I wanted something that would be medium and high power on my new N5. Knowing this would require eyepieces of the shorter focal-length variety, I knew I was in for a challenge. I always hated the short focal-length Plossl and Orthoscopics, their eye-relief was just to small and therefore uncomfortable to use. I knew right away that I wanted eyepieces that had at least 15mm of eye-relief. I always hated having my eye practically touching the eye lens. On a tight budget, I was led to the venerable Vixen Lanthanum series of eyepieces
