  • Description

    The Celestron TrailSeeker 100 Spotting Scope offers huge optics with outstanding light-gathering capability and a whole lot more! You've seen the photographers who stand along the sidelines at a football game, right?  Ever noticed how BIG their lenses are?  They spend the money on large aperture optics because big lenses offer greater resolution in demanding light conditions, and everyone is hoping for the money shot.  

    The Celestron 100mm TrailSeeker is a money shot spotting scope!  With a diameter of almost  4 inches, you will notice brighter images in those tricky yet beautifully lit hours of dusk and dawn.  Objects that disappear into the shade of a tree or the gathering gloom of deep shadow with smaller optics will pop into view with the TrailSeeker 100.  Celestron's outstanding XLT coatings are applied in multiple layers to the optics to maximize light transmission and provide further increases in contrast, sharpness, and color rendition.

    Advanced features, such as an interchangeable zoom lens, rotatable tripod mount, and a dual focus mechanism are built into this well-designed spotting scope, and protection from dirt, dust, water and fogging are standard via the heavy-duty, rubber-armored, Nitrogen-purged body.

    Interchangeable zoom eyepiece

    The Celestron TrailSeeker 100 comes with a high quality 22x - 67x zoom eyepiece. This magnification range is classic for a large 100mm spotting scope. It gives you a relatively low power, wide angle view at 22 times as far as your eye can see, and zooms up to 67x to really bring your subject in close. The 22x-67x zoom eyepiece is not built into the spotting scope itself, but is interchangeable, allowing you to add additional eyepieces to your repertoire of observing accessories.

    The TrailSeeker 22-67 zoom eyepiece offers good eye relief at both ends of the magnification range—18mm at 22x and 15mm at 67x—enough to enjoy a comfortable observing experience, even if you wear eyeglasses.

    Dual focus mechanism and sliding lens shade

    To cut glare and increase contrast, the Celestron 100mm TrailSeeker comes with a built-in, sliding lens shade. Just pull it forward when you need it, and push it back out of the way when you don’t. You will appreciate this feature when the sun is at your left or right, causing contrast-killing light to skip across your optics, and if it rains, the lens shade will keep water droplets off the glass, or at least delay it a bit.

    The dual focus mechanism on all Celestron TrailSeeker’s gives you two choices when it comes to focusing your spotting scope. Sometimes all it takes is a twist of the larger coarse focus knob, especially at lower powers. But when you are pushing your magnification to the max, you will really appreciate the ability to critically focus the image via the fine focus knob.

    Rugged waterproof, nitrogen-filled housing

    A good spotting scope should be able to accompany you in all sorts of weather, and the Celestron TrailSeeker 100 model is more than up to the task. The ruggedized, rubber-armored housing is purged of all moisture and then filled with Nitrogen. This procedure keeps water on the outside, where it belongs. No need to worry about rain, heavy dew, or for that matter, coffee, from penetrating into the optical housing or sensitive mechanical parts of the spotting scope. And what’s more, your optics will not fog in overly humid environments or when there is a large temperature change; the Nitrogen inside the TrailSeeker makes sure of that.

    The 52335 TrailSeeker model has a straight body style. Whether you choose a straight or an angled body style is really personal preference. Some people prefer a straight body style because they feel it is easier to find your subject quickly.  It also works well if you are laying on the ground when using your spotting scope, but remember, when standing, your tripod will need to be tall enough to bring a straight-through TrailSeeker in line with the user's eyes to avoid a sore neck or back. The built-in rotatable tripod mount will allow you to position the focus mechanism right where you want it. If you prefer an angled spotting scope design, the TrailSeeker 52334 model is also available.
