De Bresser Spiegeltelescoop 130/650 met EQ3 montering is een lichtsterke Newton spiegeltelescoop (ook wel een reflector telescoop genoemd). De meer ervaren astronoom zal weten dat licht een belangrijke factor is dan vergroting. Deze mensen zullen de grote 130 mm spiegel op prijs stellen, die daarmee een significante hoeveelheid aan licht kan worden verzameld en gereflecteerd. U zult met gemak in staat zijn om zeer gelegen objecten in het zonnestelsel gedetailleerd te bekijken. De 130 mm opening en een brandpuntsafstand van 650 mm met een lichtsterke brandpuntsafstand van f/5.0 geven bij een maximale vergroting van 260x nog een mooi strak beeld. De EQ-3 monitoring is sterk en solide. Door gebruik te maken van de vermenigvuldigde barlowlens kan men grotere vergrotingen bereiken. Het brandpunt van de telescoop zal dan verdriedubbeld worden. Erg handig om onze maan en planeten te bekijken. Laten we op! De kijker wordt door het gebruik van een barlowlens minder lichtsterk. Daarom wordt een barlowlens alleen gebruikt voor zeer betrouwbare objecten zoals de maan en planeten.

Favorite Hebrew Reference Book
Format: Hardcover
This is the Hebrew grammar that I use the most often. While I also use Williams and Arnold and Choi, this grammar is more comprehensive, and its size certainly reflects this. It probably betrays my inclination towards the exactness of Greek to like this grammar so much. As my Hebrew professor often tells us, all these grammar categories are contrived to some extent, so at some point it isn't helpful anymore to go further in depth on the uses of the so-called "cases."
All in all, I usually find it easy to locate the grammatical point in which I am interested, though sometimes I have to resort to looking up every instance a Hebrew particle occurs throughout the book. For this looking up of various nuances of a particle, I sometimes find Williams more user friendly. Nevertheless, Waltke and O'Connor's volume has been my resource of choice.

deep
Format: Hardcover
If you are a serious student of Hebrew this is the only way to go. The book explains how the language is built from the ground up. If you are like me you have found learning Hebrew challenging (that's a joke). I have tried learning vocabulary, rote memorization, even coming up with silly English sentences to help me remember words (The goddess "Hera" is quick) (sad, I know). This tool is essential approaching the language from the building block side of things and I am now able to look at the prayer book and recognize forms and tenses I never understood before. It is for the serious student who REALLY wants to learn the language.

Can't do Without
Format: Hardcover
I have been a fan of Gesenius for a long time. While I knew there was updated information to consider, I thought his text was enough. But although his text is certainly still necessary, and necessarily covers issues that the book reviewed here does not, it is clear that one must turn to Waltke & O'Connor to reach a greater level of accuracy. Writing so long after Gesenius, they have presented new and accurate information based on the latest research, not only of Ancient Hebrew, but also based on cognate Semitic languages.
I have found the sections on Hebrew verbs the most enlightening and correcting, e.g., that the Pi'el stem is NOT intensive. Such intenseness must be detected from a combination of the lexical verb meaning, the stem, and the text/co-text. This book also presents other up-to-date information on the forming of nouns from verbs, etc.
As others have noted, the layout and presentation is great. It really can't be presented any easier, I don't think.
One must read Gesenius, for he presents very important information across the board, including much on phonology and linguistics not covered by Waltke & O'Connor. But to stick with Gesenius will leave one in error on some points. Waltke & O'Connor, simply put, make the corrections and make studying Biblical Hebrew exciting, and even much easier to learn.

Best Of The Best
Format: Hardcover
This is the best book I've ever yet read on Hebrew Syntax as was used in the Tanakh. You can't go wrong with this, even though at times, the English-language linguistical jargon may give you a headache, the authors were quick to point out that Hebrew cannot really be clearly defined with English Grammar terminology. But it's format is easy on the eyes.
You will often find yourself flipping back a page or two at a list or chart, for whatever they're explaining, but I don't understand how you could have a problem with that. I first saw this at the Portland City Library in PDX, Oregon, and vowed to myself I was going to buy it, no matter what the cost. It's worth it's weight in pure platinum..!

Hard to Beat
Format: Hardcover
Waltke's grammar is about as good as it gets with Hebrew Grammars. Considering the subject matter and its scope one has to expect a monolith like this 700pg jumbo sized monster. But this isn't just some pedantic and wordy school book, it is accessible (assuming that the reader has a basic understanding of Hebrew already), rich with Biblical examples, and comprehensive (at least as far as a grammar can be). This book has set a standard for Hebrew Grammars and is a must for the serious Hebrew student.
