Telescopes

So many telescopes, so little time. Every observer has their own set of priorities but these articles will help you decide if a scope you’ve been considering is right for you.

Levenhuk Strike 900 Pro Refractor Review

Levenhuk Strike 900 Pro

The Levenhuk Strike 900 Pro refractor and EQ2 mount.

The burgeoning astronomy enthusiast faces one of the most difficult decisions in the hobby – what to choose for a first telescope? The choice is difficult not only because of the vast range of available options but more so because of a lack of awareness of the viewer’s own preferences and tendencies. Ideally the first instrument will nourish a love of viewing the night sky that will enable the observer to get over any inconveniences or difficulties that might be encountered early in their journey.

I tried to keep these considerations in mind when assembling my impressions of the Levenhuk Strike 900 Pro – an equatorial mounted, long focus refractor kit clearly designed with beginners in mind. Before we start I do want to point out that this telescope was provided by Levenhuk on loan for the purposes of this review and I have spent the past four weeks putting it through its paces.

Is an 8″ Dobsonian the Best Telescope for a Beginner?

A boy and his Dob viewing the Moon.

Follow any discussion of a beginner asking about a first telescope and it won’t be long before an 8″ Dobsonian is suggested. It might be the most recommended scope for beginners, and not without good reason, though there are several factors that should be seriously considered before buying one.

A Dobsonian is a Newtonian reflector on a simple alt-az mount. Before John Dobson popularized his simple, inexpensive mounting method, German equatorial mounts were commonly used, which were by necessity large and heavy, and thus expensive. By comparison an 8″ or greater Dobsonian becomes relatively affordable and portable.

Orion StarMax 90mm Maksutov-Cassegrain Review

orion-starmax90mm

During the Summer of 2013 I started learning the constellations and viewing the night sky from my back yard with a pair of 8×40 binoculars. While these show many more stars than can be seen by eye and are great for viewing wide fields, I quickly became interested in closer views of the Moon, planets, and brighter deep sky objects, and began looking for a small telescope.

I wasn’t sure how much use a telescope would see and I didn’t want to dedicate space to a large one so I was drawn to Maksutov-Cassegrain telescopes, which are among the most compact designs, have a reputation for excellent optical performance, and are well suited to viewing the kinds of subjects I was interested in observing.

I found that the Orion StarMax 90mm (that’s the Orion link, here it is at Amazon) and Celestron C90 (B&H, Amazon) both had many good reviews and seemed to offer great value. They are both made by Synta Optical and use a very similar Optical Tube Assembly (OTA). The main reason I preferred the StarMax was that the included accessories seemed more useful for looking at the sky than those that come with the C90, which is configured as a terrestrial spotting scope.

So in late September of 2013, I purchased the Orion StarMax 90mm Mak as my first telescope. What follows are my impressions from using the telescope over the past year and a half.

Using the AWB OneSky as a Travelscope

My OneSky travelscope in action. This photo was taken before adding the shroud described below.

The surest way to improve any telescope’s performance is to get it out under a darker sky. Living in suburban Massachusetts I’d have to drive significant distances to get to skies much darker than the one available from my red zone backyard. The darkest skies I regularly encounter are on family trips to rural areas.

Of course trying to fit a telescope into a car already packed with the whole family and all the associated cargo can be a challenge. Thus begins the search for a more portable telescope or travelscope. To my thinking a travelscope can be any telescope setup that prioritizes volume and/or weight over other concerns such as aperture or mount stability. Every one has their own circumstances and priorities and so travelscopes can look quite different from observer to observer.

As I mentioned in the general review of the AWB OneSky Telescope, my intent when buying the OneSky was to use it primarily as a travelscope. The OneSky appealed to me for its packed aperture to volume ratio and ease of setup.

Celestron FirstScope Review

The FirstScope and included 20mm and 10mm eyepeices.

Small, inexpensive telescopes have an appeal all their own. Ideally they are simple to use and though they don’t collect the most light or have the highest quality optics or most robust construction, under a clear night sky they can reveal a host of wonders. In practice few of these cheap telescopes actually live up to these aspirations and many of them are so flawed in optics or mechanics as to be more frustrating than fun.

The Celestron FirstScope (you can also find it at Amazon) is a small, 76mm, reflector that has interested me for some time. It is incredibly inexpensive; the regular price is under $50 and I’ve seen it on sale for under $35 from time to time. So what makes the FirstScope any different from countless other cheap telescopes?

A well designed, compact 5″ telescope and mount for $200? It may sound too good to be true but despite a few caveats this 130mm f/5 reflector is a capable telescope at an outstanding price.

Astronomers Without Borders (AWB) is an organization that offers astronomy outreach programs all over the world. The OneSky telescope is made for Celestron in China and sold in the US by AWB to help fund these programs. My intent in purchasing the OneSky was for use as a travelscope but for now I want to focus on its suitability as a general use telescope.
