zennox 900x60. question for ppl owning one of these telescopes?
i have one and am wondering on your views of this item?
bought mine second hand but unfortunatly was not given the spare lenses, just the ones attached already so have not as yet got any use of it until i buy some lenses.
seen some reviews on argos for similar items but unsure on this one?
Larry's right. Basically,it's crap. Good for about 30x and rubbish any higher.
You'll see the craters on the moon...best at the straight edge of a half Moon because the contrast from that telescope is rotten and the craters and mountains at the straight edge are at sunset/sunrise so there's lots of shadow and bright bits which increase the contrast.
You can see the effect on here

If you point it at Jupiter, currently very bright in the south-east as darkness falls, you'll see the four brightest satellites unless one ot two of them are round the back or whatever.
You'll see them a little bit better than this, but not by much

It's best not to buy telescopes from catalogue dealers, high-street department stores, or other cheap outlets.
Don't worry about not having the other lenses...none of them are much good anyway.
The lowest power one is the most useful on that telescope.
Tough eh? Sorry. True though.
Don't go all crying and stuff will you?
My first telescopes were made from spectacle lens blanks, with a lens from an old box camera for an eyepiece.
Even worserer,hehe, than the one you've got.
I've made 9 of them since then. Proper ones.
Use it for a sun projection telescope so you don't spoil a good one.
Not that there's much to see at the moment.
The Sun is currently very quiet..

Carl Zeiss Victory FL Binoculars (10x42)
List Price: |
DescriptionZeiss takes premium optics to the next level with the Zeiss Binoculars T*FL. With Zeiss proprietary T* multi-coatings, phase corrected Abbe-Koenig prisms, special flourite element objective lenses, and now with new LotuTec coating, the Zeiss T*FL Binoculars offer extremely high edge sharpness and unsurpassed resolution, contrast and color. Flouride objective lenses also eliminate any color fringing from the Zeiss T*FL binoculars, even in low light conditions. The housing consists of magnesium reinforced by glass-fiber material, yielding a very durable and lightweight housing. The Zeiss Binoculars T*FL are waterproof and nitrogen-purged, and feature retractable eyecups for comfortable viewing and rubber armoring for a pleasant firm grip The Victory FL Binoculars (10x42) from Carl Zeiss are all-purpose binoculars that offer a large field of view. The 42mm lens provides optimum light transmission and the 10x magnification is perfect for scouting and glassing. These durable binoculars are loaded with great features that make them an ideal choice for stalking or stand hunting. As with all Victory FL binoculars, the 10x42 are specially designed to maximize your experience in the field. These binoculars utilize Carl Zeiss' optical engineering fundamentals, such as the FL Concept and LotuTec lens coating. Carl Zeiss has developed these binoculars with advanced ergonomics and perfect balance to promote comfortable use, even during prolonged observation. These premium waterproof and nitrogen-filled binoculars also feature dielectric mirror coatings for superior image brightness and contrast, twist up eyecups for operating comfort, and an award-winning offset hinge design for exceptional compactness and handling. FL Concept for Sharper Images and Vivid Colors Victory FL binoculars employ the revolutionary Carl Zeiss FL Concept -- an optical system that uses fluoride glass to achieve the highest level of performance. The FL Concept provides brighter, sharper images with highly saturated, vivid colors. This treatment also delivers extended twilight and low-light performance, even in harsh weather. Unlike ordinary optical systems, the FL Concept minimizes chromatic aberrations and virtually eliminates stray light interference, fuzzy images, and low contrast to provide clearer viewing. LotuTec Lens Coating for Inclement Weather Taking its name from the traits of a lotus leaf, the LotuTec coating on the Victory FL binoculars' objective and ocular lenses repels water so efficiently that raindrops actually roll right off the glass. And the super-smooth lens surface can be wiped clean without smearing or damaging the optics. This revolutionary coating was even honored with the prestigious Gray's Best award, recognizing LotuTec as the only optical process that allows lenses to completely shed water, even in the heaviest downpours. Victory FL 10x42 Binoculars Specifications: Magnification: 10x Objective Diameter: 42 mm Exit Pupil: 4.2 mm Twilight Factor: 20.5 Field of View (ft/1000 yards): Ww 330 Close Focus: 6.56 feet Diopter Range: +/- 4.0 dpt Eye Relief: 16.0 mm Interpupillary Distance: 54 to 76 mm LotuTec: Yes Nitrogen Filling: Yes Waterproof: 400 mbar Functional Temperature Range: -22 to +145°F Height: 6.34 in Width: 5.04 in Weight: 26.98 oz Features

Celestron NexImage Solar System Imager
List Price: |
DescriptionThe Celestron NexImage Solar System Imager is a complete CCD solar system imager capable of producing high quality planetary images with greater light sensitivity and color fidelity than comparable CMOS imagers. -- The NexImage, along with the NexImage software package, can bring out tremendous detail and reveal a final image that will rival those taken with astronomical CCD cameras costing thousands of dollars more. -- **View and capture live video on your computer screen -- **Software automatically filters out video frames most affected by poor atmospheric "seeing" leaving only the sharpest, clearest frames to be stacked and aligned into one high quality image -- **Easy to follow quick start instructions and tutorial with sample video file that will have you producing quality images your first night out -- ** -- Camera control software allows you to manually change the gain, contrast, exposure time, frame rate and color saturation using your PC -- With the 1.25" adapter barrel, the NexImage is compatible with most any telescope. In addition, the 1.25" adapter is threaded for standard eyepiece filters and can be removed and replaced with optional focal reducer lens, adding greater versatility. -- Amazon.com Review Celestron's NexImage combines a sensitive CCD imaging device with powerful image processing software in one affordable package. Now anyone with a telescope can take pictures that are simply amazing. An image of Jupiter taken with the Celestron NexImage Solar System Imager Amateur astronomers have been taking great pictures of the moon and planets by using modified Webcams. The favored Webcams for astro-imaging have been the hard-to-find Philips ToUCam and Vesta models because of their high-performance CCD chips. Now Celestron's Neximage puts the same CCD technology in a package that's ready to use with any telescope that accepts 1.25-inch eyepieces. The NexImage includes an anodized metal nosepiece that fits in a 1.25-inch eyepiece holder. When I installed the Windows based software, I also updated my Windows Media Player files. Then I simply plugged the NexImage into my computers' USB port, and I was ready to start taking pictures. The NexImage CCD is sensitive enough that I can take "snapshots" of the Moon or Sunspots (always use a safe Solar filter, of course!) even without a motor-driven telescope. The real power of the NexImage package, however, comes from its included Registax software which automatically aligns and stacks hundreds of individual AVI video frames into one sharp, highly detailed picture. I used my 8-inch Celestron Schmidt-Cassegrain telescope (similar to the Nexstar 8 GPS ) and my 2x Ultima Barlow lens to capture some beautiful pictures of Jupiter and Saturn. The sensitive Sony CCD chip in the NexImage easily shows color and detail on Jupiter that just doesn't show up when I use CMOS-based Webcams. The fine performance of the NexImage package is limited somewhat by its included video capture software. The AmCap software doesn't give me the precise control of exposure times I'd like; I wasn't able to photograph the moon Callisto next to Jupiter, for instance, without overexposing the planet. Celestron doesn't mention the other little drawback in its ads. You'll have so much fun that your hard drive will start filling up with pictures and AVIs! --Jeff Phillips Pros: Sensitive CCD chip Fits any telescope that takes 1.25-inch eyepieces Powerful image processing software Cons: Takes practice to get the exposure time just right Software is Windows only You'll fill up your hard drive with pictures Features
