  • Altair Astro Starbase Tripod Review

    Dec 07 2014 03:27 AM by

    From the moment I saw it, to putting it together and using it over 3 months - I have been extremely happy with the Starbase. It costs a bit more than a T-Pod 130 but its specifications are also far greater. The build quality is as good as it gets, the design is engineered well and executed perfectly.

    Overall, I really like the Orion XT10g. I give it 4.5 out of five stars. It takes the large apertures, lower cost and simple base of the classic Dobsonian design and upgrades it to allow modern motorized GoTo targeting for a complete newbie. The tracking is very good, and becomes excellent once PAE is performed for a specific section of the sky under observation.

  • Binocular review for 20X80 Konus Giants

    Dec 06 2014 02:28 AM by

    Konus really knocked it out of the park with these. I have looked through other large binoculars costing 2-3X as much, with these as good or actually better!

  • Hutech IDAS LPS-P2 vs Chroma LoGlow

    Dec 01 2014 09:53 AM by

    As a testament to the fact that I purchase too many filters, I was given a Chroma LoGlow filter to test. So I've compared it the the Hutech IDAS LPS-P2 filter which many (including me) consider the gold standard light pollution filter.

  • Celestron Ultima 80

    Dec 16 2014 05:54 PM by

    I had the opportunity to observe the sky with this spotting scope during my holidays last Summer. My Father in law happened to own the Celestron Ultima 80 for nature watching and shooting sport and had left the scope at his holiday house near the seaside where I spent my holidays with my family. The sky there is pretty good so you can see 5.0-5.5 magnitude stars with the unaided eye at the zenith.

  • 10 Micron GM1000HPS --- My Experience

    Dec 15 2014 12:54 PM by

    My first setup was working OK for me. I had a Celestron 11 inch HD scope a Hyperstar, Atik camera and a Celestron CGEM mount. I was getting images that I thought were wonderful and was overall very happy. The one major pain point I had was set up time and accuracy of the mount using was not always a fast fun experience. I found the CGEM mount overall worked well but there were some things that frustrated me which I will not go into here. I also wanted to do more advanced imagery… namely Satellites and Comets and I wanted it to be as easy as possible of course.

    Side-by-side comparison of the Takahashi FS-128 & TEC 140 apochromats, including observing solar system and deep sky targets.

  • WO XWA 9mm Eyepiece Review

    Nov 29 2014 10:21 AM by

    I really like the WO XWA 9mm. It really has me rethinking trying to buy more eyepieces from this line because even though a 9mm is a heavily used focal length, I think a 20mm would be perfect for my old Celestron C8 SCT. It is just a really crisp and fun eyepiece to use, and if the other focal lengths are as good as this one, this is going to be a real winner for William Optics.

  • The William Optics FLT 151 Triplet APO Refractor

    Nov 29 2014 09:48 AM by

    Overall, The William Optics FLT 151 OTA is an impressive telescope with exemplary craftsmanship and excellent optical performance. I would highly recommend this telescope to anyone wanting a fine 6” refractor.

  • Three Deep Sky Video Cameras for Under $100

    Nov 27 2014 11:44 AM by

    Video astronomy has been around for more than 20 years. And most will associate it with lunar, solar and planetary imaging/viewing. However, with the advances in video surveillance cameras and astronomy specific adaptations of these cameras in the late 90's and early 2000's, video cameras have been increasingly directed at a wide range of deep sky objects. While it is possible to spend hundreds of dollars to nearly two thousand dollars on some of the latest video astronomy cameras, I have been amazed at the depth and breath of deep sky objects which are accessible with cameras available for less than $100.

    William Optics WO-Star71 71mm f/4.9 Apo Imaging Refractor It is very well designed, solidly built and produces sharp images. What more could you want?

    Of all the mounts I have purchased over the years this one is quickly becoming my favorite.

  • Sky-Watcher Flextube Dobsonian: SkyLiner 400p GoTo

    Nov 26 2014 12:57 PM by

    Overall, I love this telescope, it has a few niggles but in terms of the purpose it was built for, and the purpose I wanted it for, it serves excellently. However, its size and its bulkiness are a serious problem, on reflection, if I was to go back and buy again, I would go for the 14" version, the 16" is that little bit too large for it to be practical. Over all though, I am very fond of this scope, and you'd be hard pushed to find something better for the price.

  • The Atmospheric Dispersion Corrector

    Nov 26 2014 11:33 AM by

    We cannot influence the seeing conditions, but the refraction can certainly be kept under control; this is not well known in he amateur astronomy society.

    With this article we wish to change this.

  • Review of the LHIRES LIte Spectroscopy by Shely...

    Nov 26 2014 11:12 AM by

    The LHIRES Lite is a great hit at daytime public presentations; everyone likes color, and the detail in the spectrum impresses people. It’s a winner. I also use it as part of an in-class show about the Sun that has been very well received by schoolchildren. It can also present spectra of spectral calibration lamps, compact fluorescent bulbs, etc. These are not so visually impressive as the solar spectrum, but still show nice detail and are good for teaching purposes.

  • Phone/Tablet Apps and the Practical Astronomer

    How can an astronomer harness the great power of these new devices, without wasting enormous amounts of time figuring out what is really useful?
