Are explore scientific telescopes any good?
This telescope is an excellent choice for anyone interested in capturing high-quality deep-sky DSLR astrophotography images. Over the course of 4 years, I photographed more than 50 deep-sky objects with it. The Explore Scientific ED80 tops my list of best astrophotography telescopes for beginners.
What is APO triplet?
Apochromatic (APO) lenses are designed to bring three wavelengths of light (red, green, and blue) into focus in the same plane. In contrast, achromatic lenses are corrected to bring two wavelengths into focus in the same plane.
What is a triplet refractor telescope?
Triplet Refracting Telescopes, or Triplets, as they are commonly referred to, are telescopes with 3 lenses. When compared to doublets, these are more expensive because they tend to be much better at color correction and will give the user a much cleaner view.
Where are explore scientific telescopes made?
Headquartered in Springdale, Arkansas, the company designs and manufactures telescopes, spotting scopes, binoculars, microscopes and other scientific devices. Products are manufactured in China by JOC and imported.
What is the difference between achromatic and apochromatic?
Achromatic lenses are corrected to bring two wavelengths into focus in the same plane – typically red (~0.590 µm) and blue (~0.495 µm). Apochromatic lenses are designed to bring three colors into focus in the same plane – typically red (~0.620 µm), green (~0.530 µm), and blue (~0.465 µm).
What is a petzval telescope?
Petzval Telescopes are the highest end of refracting telescopes in terms of clarity. Because they use a 4 lens optical system they are exceptionally well corrected, they have very fast focal ratios, and they are the easiest to use of all astrographs in the world of astronomy.
What is the difference between a doublet and a triplet refractor?
Triplets do not only have better color correction, but also have better correction for spherical aberration. So even if you use a filter, even a narrow-band filter, you will find that triplets give you sharper stars than doublets, provided that they have similar aperture, F-ratio, and glass material.
What is the difference between doublet and triplet opals?
Doublets consist of two layers adhered together with glue: The thickness of the opal in a doublet can vary, however it is generally thicker than the opal found in a triplet. The edges of the slice of opal are generally rounded off (if there is enough opal) to give the stone a cabochon (domed top).
Who makes Bresser telescopes?
The Bresser Corporation is a Germany-based manufacturer of binoculars, telescopes and microscopes.
What can you do with the Explore Scientific ed102 triplet lens?
The triplet lens design means that the ED102 produces a flat field of view for astrophotography This telescope is an excellent choice for anyone interested in capturing high-quality deep-sky DSLR astrophotography images. Before upgrading to the ED102, my primary astrophotography telescope was an Explore Scientific ED80.
What kind of Mount does Explore Scientific ed102 use?
My Explore Scientific ED 102 Carbon Fiber refractor. Modest German equatorial astrophotography mounts such as the Orion Sirius EQ-G or Celestron AVX will have no problem handling this lightweight tube, with all of your photography gear included. I mounted the Explore Scientific ED102 to a Sky-Watcher HEQ5 equatorial telescope mount for many years.
Is the Explore Scientific ed102 fcd-100 Hex focus?
The Explore Scientific ED APO 102mm f/7 Deluxe FCD-100 Hex-Focus is a short focus refractor. It is sold as a tube-only configuration packaged with tube rings, two focuser-extension adaptors and a star diagonal.
How to fix the Explore Scientific ed 102 CF?
A simple fix is to use a rubber band at the base of the dew shield to prevent it from slipping. Despite this minor annoyance, the overall build quality of this instrument is impressive. There are two easy ways to attach a guide scope to the Explore Scientific ED 102 CF.
