Explore Scientific Aluminum 102mm APO ED Refractor - OTA
(Backordered until August 2020)
If you are looking for an apochromatic (APO) triplet refractor that is professional-grade, portable and also durable, then the Explore Scientific ED102 Triplet APO is definitely worth considering. This 102mm APO refractor uses EMD-coated optics, and includes a heavy-duty, 2-speed focuser, a 99% dielectric coated 2” diagonal (with a 1.25” adapter), and two focal extenders.
The Explore Scientific ED 102mm F/7 APO is also highly versatile telescope, given its size and weight. (Check out the Carbon Fiber 102mm FCD1 APO here for an even greater (~30%) weight reduction). Not only will you be able to take advantage of high-quality optics for your astro imaging, (we recommend using a field flattener if you are thinking about getting serious!), you can also use it for astronomical and terrestrial observations, or even use it as a finder/guider scope on a larger rig. This sheer size of this scope (similar to many other 102mm refractors) makes this quite the multi-purpose instrument.
Why Buy The Explore Scientific ED 102mm APO Triplet Refractor?
- Small and Versatile - Bigger doesn’t always mean Better! 102mm refractors are portable in general, and so is this scope. It is 23.75” long (with the collapsed dew shield) and 9.6lbs, making this scope quite versatile. This ED 102mm APO Triplet can be used as your main bird, or even as a (really nice) finder/guider scope for your larger setup. You could even piggyback this telescope on a larger Newtonian or SCT. Don’t forget, you could also use this scope for great terrestrial (daytime) viewing!
- Virtually No Chromatic Aberration - This APO Triplet Refractor scope is great for both observing and astro imaging (especially with wide-field framing). You’ll really notice the omitted chromatic aberration with lunar and planetary visuals. Note: If you are starting to get serious with astrophotography, we recommend getting a field flattener to reduce unwanted curvature in your shots.
- Heavy-Duty Focuser - The included, Rack & Pinion focuser is strong and reliable. It is dual speed, 360-degree rotatable (to help frame your shot), and includes graduation marks (helpful if you are needing to return to the same focus). Note: You’ll notice that a lot of the weight of the scope will actually is come from the back, especially with a 2” eyepiece or a DSLR attached!
- Optics Are ED (Extra-Low Dispersion) and EMD Coated - This scope yields crystal-clear results with its Hoya FCD1 ED optics. Glass like this is particularly advantageous with lunar and planetary imaging.
- Zero-Hassle Camera Attachments - Attaching your imaging equipment and accessories is a breeze, no matter the size or weight. Easily place a modified DSLR or a smaller CCD astro-imaging camera on the back.
