For the folks at Explore Scientific, developing a telescope with comet discoverer and author David Levy was a dream come true. David Levy has spent a lifetime inspiring people of all ages to look at the stars through his comet discoveries, his writings, and his lectures. His dream to show people the beauty of the night sky has culminated in the formation of a non-profit organization devoted to outreach in astronomy, called the Sharing the Sky Foundation. But outreach on a global scale takes sustained effort and money.Explore Scientific shares David''s dream. So they embarked on a project to co-design a telescope with Levy that could help support Sharing the Sky through through the sale of the product, but they wanted much more than just another wide field telescope.

Most Rich Field Telescopes - while perfect for comets, nebulae, and galaxies - are not optimized for high magnification observations of planets. Explore Scientific''s Scott Roberts explains:

"Our challenge was to design a portable instrument that has enough aperture to observe the broad range of celestial objects with an optimized optical design to serve as a true RFT that can also work well for high magnification observations of planets. We also wanted the telescope to serve as a serious optical solution for astroimaging. In short, we wanted a telescope that could do almost anything; a telescope that would be perfect for beginners to advanced astronomers alike.

"To solve the problem, we chose a Maksutov-Newtonian optical design. The Maksutov corrector lens is a great solution that produce round star images that are well corrected from center to edge. Durable Enhanced Multilayer Deposition (EMD) Coatings with a multicoated Maksutov corrector lens and enhanced coatings on the primary and secondary mirrors deliver bright, high transmission images across the visual spectrum. Aside from the fact that this is a fantastic visual instrument, the Comet Hunter, with its fast f/4.8 focal ratio, light-weight zero-expansion carbon fiber tube, and two-speed focuser, is a true astrograph, perfect for use with popular CCD astroimaging cameras."

Called the David H. Levy Comet Hunter Telescope, this instrument is a rich field telescope (RFT) capable of showing faint objects over a wide field of view (generally two degrees or more). Comet hunters like Levy use RFTs to visually sweep the sky for comets, but this type of telescope is also preferred for observing all types of faint deep sky objects such as nebulae and galaxies. The Explore Scientific Comet Hunter Telescope suggests the use of an optional Explore 2" 30mm eyepiece with a wide 70 degree apparent field. This eyepiece, combined with the short focal length of the telescope, produces an amazing 2.86 degree true field of view with a 6.2mm exit pupil. Sometimes called visual equalization magnification, using the right low power eyepiece will produce an exit pupil that nearly matches the fully dilated eye. This allows you to see to the faintest observable limit of the telescope''s aperture, which is critical for searching for faint objects such as distant comets. Explore Scientific recommends the 30mm eyepiece because the exit pupil it produces comes close to the average fully dilated human eye.

We understand that the aquisition of a precision instrument represents an important investment to its owner. That is why every Explore Scientific Dave Levy Comet Hunter Telescope is supplied with heavy-duty, custom-cut, foam lined instrument case. The case uses four butterfly latches so that the lid can be complete removed for easy access to the items inside. The bottom of the case has rubber feet to lift the case off the ground to keep the case clean and dry.

As an added bonus and incentive to reach for the stars, each Explore Scientific Comet Hunter Special Edition Telescope will come with a certificate signed by David Levy! Put a true astrograph telescope in your hands tonight.

  • Customer Review
    First, let me say that I do my homework where a new scope purchase is concerned. I've been an amateur astronomer for close to 15 years and have been taking astro-photos for three.

    THE GOOD:
    This scope is a better astronomer than I am. It has let me know where my skill limits are and challenged me to improve. My previous scope is an F-4 newt undermounted on an older Eq mount. I decided to upgrade my kit as a whole and shopped for several months before settling on this scope and an Orion Atlas EQ-G.
    As I indicated, I very much like the scope. I thought that a fast scope of any kind would exhibit field curvature or coma and so was originally shopping for an >F-6 refractor. I'm glad I gave this one a chance. I don't have an unlimited budget, but this was indeed money well spent. If you are serious about AP, this is a good upper mid-range scope and should be considered.
    Coma is not a problem, I have to look hard to spot it, and can only do so at the very limits of the field. All aberrations are slight and are well outside of the APS-C frame of my Canon 1000D. I was at the limit of my previous scope. I believe this one will allow me to progress "less difficultly" up the already steep learning curve of AP.
    In my opinion, the finish is a thing of beauty. The scope is well protected in a hard case with fitted foam interior and can be stowed with rings and dew-shield attached. The rings are a nice touch too, doubling as a carry handle when mounting the scope (no moment of fear). The optics are well thought out. The finder is very nice indeed and feels well built, its adjustable illuminator is easy to use, just watch that you don't accidentally turn it on while stowing it. The focuser is smooth and easy to use. It supports my Canon well. The scope cools down quickly and is ready before I am. I've taken some nice shots since I bought it. The scope frames M81-M82 nicely at prime focus.

    THE BAD:
    The secondary collimation screws are difficult to use, and one of the primary collimation knobs feels "a bit wrong". I'm loath to disassemble such a beauty and will be calling on ES to fulfill their warranty in this department. The scope is prone to dewing (as are all scopes with a front element). Some form of active dew control will prove necessary if you observe in a humid climate.

    THE UGLY:
    This is the second scope I received. While the first arrived very quickly, the secondary holder had come loose during shipping. As a result, the primary and secondary were both a tragic sight. This was (without disassembly to check) seemingly due to a loose center screw on the holder itself. Ordering from Astronomics was worry free in that regard though. They bent over backwards to see that I had my scope in my hands as soon as possible afterward. I do commend Michael and the rest of the group at Astronomics on their customer service. The second scope was packed much more thoroughly than the first. Possibly an indication of a change in practice?

    MY RECOMMENDATION:
    There are some very nice scopes available these days for similar amounts. Do your homework and find the one that suits you. Remember to leave budgetary room for a good solid mount (the Atlas carries this scope and all my imaging kit easily and is an excellent choice.) If you feel the ES152 agrees with what you are trying to accomplish... Well you could do a whole lot worse. I'd do it again, problems included.

    Clear Skies,
    R
