DescriptionProperly designed Barlows do wonderful things. First, they amplify power while retaining the eyepiece's eye-relief. Second, they slow the telescope's f/#, which improves eyepiece sharpness. Third, the designer can introduce compensations for eyepiece aberrations.Tele Vue's 2" 2x BIG Barlow, 1 1/4" 2x and 3x Barlows were envisioned as magnification windows. Multi-coated high index glasses assure optimum aberration correction, exceptional contrast and virtually no light loss. Tele Vue Barlows achieve their design goals even when tested by the fastest scopes. They even improve our competitor's eyepieces and telescopes!For eyeglass wearers, the Big Barlow is perfect for doubling the power while retaining the eye-relief of 2" Tele Vue eyepieces such as the 55mm Plossl, 35mm and 27mm Panoptics (requires use of Panoptics Barlow Interface) and 20mm Nagler Type 2.Our design approach includes mechanical conveniences. The Barlows are parfocal with our eyepieces and the BIG Barlow includes a parfocal 2" - 1 1/4" adapter. The BIG Barlow is threaded for 48mm filters and has a captive lock-screw. Both 1 1/4" Barlows are threaded for 1 1/4" filters.Barlows do more than just increase magnification; they also retain eye relief (or in the case of long focal length eyepieces, actually INCREASE eye relief). A high quality Barlow must be properly designed and manufactured in order to avoid compromising a telescope's color correction and spherical aberration corr |
Memory
I wanted to write my story. It's that simple. I felt driven by this desire for a very long time. It was not until I turned twenty-eight I bought a computer and a typing tutorial and began the task of putting my words to paper. (Journals do not count.) This was much more difficult than I realized when the notion of a book hit my mind. Apart from learning to write and have a few grammar online courses that I took the reading reports. I have read, waiting be inspired to read a book that was similar to that he had to say, but I ended up disappointed. Do not get me wrong, I read some fantastic memories the way, including Angela's Ashes, Blackbird and Fisheries incidence, but I was wanting. Ultimately, it was the story of another person and I was no closer my own before.
About this time someone recommends a book entitled A Tale Margaret Atwood Handmaid. Before finishing this book, (a piece of compelling fiction by the way) I started writing my own book, the first feeble attempt. Fiction was freed to write my story. The novels were so bold, take risks and have stories requiring the reader to sit up straight and pay attention. While reports were flooded with the passage of time, developing one case after another in a linear fashion. I could almost hear the ticking of the clock in the background as I read to reach the goal. The only exception was Angela's Ashes by Frank McCourt. He performed a little magic that I could not find out the actual reading, so a magic that could not duplicate.
In writing my memoirs kept asking me, what is truth? I do not think I've found that the total response, but the book became a journey to discover the truth that was inside me, I had hidden truths myself. The events in the book all actually happened. I did not fiction at an event to show a truth, but the truth must be in the event. I needed a theme, something that would corral my memories and force them to be sorted and ready.
Throughout my book, the concept of leakage occurs in many ways more evident in the prologue and in the epilogue. Why do we run from the pain? What are different ways in which people are fleeing? Is fleeing always produce the desired result? Sometimes we run into something and sometimes we're running from something. All these questions were asked and answered never, because who wants the answer when the question is enough?
I did not know in advance what stories would surface, did not know how I was going to end it or what would emerge culminating experience in the dusty pages of the past, I just knew that it would. I was surprised at every turn. I was delighted with the humor that emerged from the pain, humor I did not know existed until they started digging. I laughed, cried spontaneously and unexpectedly at the smallest provocation. I was hoping that the reader will also be amazed and laugh or mourn when least expected.
The book was written in present tense. I wanted to convey a sense of immediacy and timelessness. The passage of time contained in the present moment and the moments are developed in the here and now. He hoped that readers grow right along with the child making their own unique discoveries along the way and the child separately from the others by a pane of glass at last I know she was not alone.
When the book was that it had been six long years. My story was written. But it was not and never will be. Memories can not be truly known, written or documented, but only implied, as seen through the blurred lens of time. But I told him a story and I could go on telling stories till the land of my past and my experiences and all of them peppered with the same amount of truth and fiction. And maybe somehow Somehow my story is known through all the words have been written and all the words are written.
Maybe not.

3x Barlow = waste of time?
K20 I'm using a lens to look at the moon - it's perfect - I can see the moon nice and clear. It is not as magnified as I would like - so to change my lens SR4. - WHOA too big! - But still a good photo, but not enough field of vision. So - then changed my 3x Barlow lens and an image I can not at all, only comes as a huge mass of white fuzzy blur! Am I doing something wrong here? Should I use this lens Barlow with another type of lens? I need some advice on how to use it effectively. (I'm using a small PowerSeeker60 Celestron: P - if that helps) Thanks in advance! =) Jonathan (Armour Astronomer in the ingredients!)
Some are not Barlows parfocal, which means it may have to adjust the focus after insert the Barlow. In addition, make sure there are other accessories and between Barlow and the eyepiece, as a diagonal. The correct order should be: focus, diagonal, Barlow, eye.

Celestron 52268 C90 Mak Spotting scope (Black)
List Price: |
DescriptionThe Maksutov optical design is recognized for being a portable design that is easy to use and has a variety of applications, making it an excellent choice for both terrestrial and astronomical usage. This C90 Mak has excellent optics with razor sharp images over a wide field, along with built-in T-adapter threads for adapting SLR cameras. It comes with a 32mm eyepiece, 45° erect image diagonal, and 8x21 erect image finderscope. Celestron’s 52268 90mm Maksutov Spotting Scope delivers excellent high power optics in a compact, affordable package. The 52268 package includes a backpack style soft carrying case, an 8x21 erect image finder scope, a 1.25 inch size correct image 45* prism diagonal, and a fully coated 32mm plossl eyepiece for a magnification of 39X. The Maksutov-Cassegrain design of the C90 uses a combination of mirrors and lenses; this “folded” optical system has a focal length of 1250mm in a body only twelve inches long. The Maksutov design delivers high power views without a trace of the chromatic aberration, also called blue fringing, that can distort high power views in competing refractor style spotting scopes. At 40X magnification where some low cost spotting scopes start to seem fuzzy, the C90 is just getting started. The C90 uses the same 1.25 inch eyepieces used in astronomical telescopes. The standard equipment 32mm plossl eyepiece yields a magnification of 39X, but many other eyepieces can be used to vary the magnification. The Celestron model 52268 seems very well built, with excellent multi-coatings visible on the front lens. The real beauty of this 90mm Maksutov spotting scope, however, is in the view it offers. When I use an optional 12.5mm eyepiece to look at Jupiter at 100X I can clearly see Jupiter’s major cloud bands as well as its four moons. When I look at the Moon and stars I can easily push the magnification to 200X with an optional 6mm eyepiece. When I look at birds in the backyard, I’m treated to delightful views full of vibrant color and crisp detail. With a close focus distance of only 15 feet, the detail and texture I see is simply amazing. High magnification viewing requires a solid tripod, of course. Celestron’s Heavy Duty Altazimuth Tripod comes with slow motion controls to allow the scope to be pointed precisely, and I can clamp the dovetail base on my CG5 mount for astronomical use. The other drawback to high magnification viewing is a narrow field of view; high magnification makes it hard to follow moving targets like birds in flight. Overall the Celestron C90 Maksutov Spotting Scope does a fine job as a companion to good pair of binoculars. The C90 also doubles as a portable astronomy scope; it won’t show the flag on the Moon but it will show thousands of craters on the Moon as well as showing the moons of Jupiter and the rings of Saturn. --Jeff Phillips Pros: Compact and portable Excellent high power optics Upgradeable with 1.25” eyepieces Adaptable for astronomy and photography Cons: Not waterproof Features

Orion SpaceProbe 130 EQ Reflector
List Price: |
DescriptionShips to the U.S. including Alaska, Hawaii, and Puerto Rico. Orion SpaceProbe 130 EQ Reflector Telescope An affordable but very capable telescope130mm aperture and 900mm focal length for great all-around viewing performanceIncludes sturdy tripod and equatorial mount for hands-free celestial trackingIncludes two eyepieces, finder scope, focuser, collimation cap, and FREE Starry Night astronomy softOne-year limited warranty A lot of folks shopping for their first telescope tell us that they have always had a fascination with the stars. They've been wanting to get a telescope for a long time, they say. We understand very well the lure of the night sky. It has intrigued mankind for millennia with its beauty and mysteriousness. And still does. So it's only natural to want to know more about it, to get a closer look. If you share this fascination, and are ready finally to spring for that telescope, then consider the affordable but very capable Orion SpaceProbe 130mm EQ Reflector Telescope. Sporting the classic long-tube Newtonian design, the Orion SpaceProbe 130mm provides great all-around viewing performance. One minute you can be studying lunar crater formations at high power; the next, the ethereal glow of a nebular star factory. A few minutes later, the ringed visage of Saturn. All served in crisp detail by way of the SpaceProbe's light-gathering 130mm (5.1") primary mirror of 900mm focal length (f/6.9). The mirror lies at the base of the rolled-steel optical tube, which is outfitted with a smooth rack-and-pinion focuser. It accepts 1.25" telescope eyepieces, including the two fully coated Explorer II telescope eyepieces that come standard with the Orion SpaceProbe 130mm: a 25mm for low-power viewing at 36x and a 10mm for higher-power looks at 90x. Also standard is a 6x30 achromatic finder scope to help home in on celestial targets. The mount is our sturdy EQ-2 equatorial model, with adjustable aluminum legs and accessory tray. Slow-motion controls allow fine The Orion SpaceProbe 130 EQ Reflector is a Newtonian reflector telescope packaged with a sturdy equatorial mount, two Explorer II eyepieces, a 6x30 finder scope, and Orionâs Starry Night Special Edition software. Invented by Sir Isaac Newton, reflector telescopes provide more light gathering power per dollar than any other telescope design. With 130mm (5.1 inches) of aperture, the SpaceProbe 130 produces images that are twice as bright as 90mm telescopes and more than four times brighter than 60mm beginner scopes. The Orion SpaceProbe 130 EQ Reflector with its Explorer II eyepieces serves up bright, clear images of the Moon, the planets, and even deep space objects like star clusters and galaxies. The 25mm eyepiece magnifies the image by 36 times; when I look at the Pleiades or Seven Sisters cluster at 36X the SpaceProbe 130 shows me a bright open cluster with dozens of point-like stars filling the field of view. When I use the 10mm eyepiece (90X magnification) the lunar disk fills the field of view and the rings of Saturn are plainly resolved. And when I use an optional Ultima 2X Barlow with the 10mm eyepiece for 180X magnification I can see the cloud bands of Jupiter and pick out individual stars in bright globular clusters like M13. The EQ2 equatorial mount included with the Orion SpaceProbe 130 EQ Reflector comes partially assembled, but it shouldn’t take long to set up. The trick to using an equatorial mount is to point the polar axis at Polaris, the North Star. Once the mount is aligned and balanced, the telescope tracks stars and planets at high power with just a turn of one slow motion knob. You can even add an optional motor drive for hands free tracking. The Orion SpaceProbe 130 EQ Newtonian Reflector Telescope is a simply a great value. The Explorer II eyepieces deliver bright sharp images of the Moon, the planets and the stars, and the EQ2 mount can be motorized for hands free tracking. --Jeff Phillips Pros: More than 4 times brighter than 60mm scopes Includes two eyepieces and a 6x30 finder Solid equatorial mount and aluminum tripod Starry Night software and SkyTheatre DVD included Features
