Celestron 22403 Inspire 100AZ Refractor Smartphone Adapter Built-In Refracting Telescope - Blue

Product Information

With a large 100mm (4”) objective lens, this telescope has enough light gathering ability to bring out impressive detail in celestial objects. You can expect sharp, bright views of Jupiter’s four Galilean moons, its cloud bands and Great Red Spot, the rings of Saturn, the trapezium in the Orion Nebula, and beautiful Ple ia des Open Star Cluster. Celestron’s XLT optical coatings improve light transmission, enhancing the views even more. The telescope also includes a 90-degree erect image diagonal, so you can use it during the day to view birds, wildlife, landscapes, and more.

Outside the solar system, what you can see with the Inspire 100AZ broadly depends on your sky conditions. Under a light-polluted sky, you are basically limited to seeing the cores of the brightest galaxies, open star clusters, and some of the brightest nebulae. With good skies, however, you can see a lot more. Keep in mind that we’re not asking for perfection-what we’re talking about is being able to at least somewhat make out the Milky Way. Under skies like these, open star clusters explode into colourful gobs of stars straddled by dark dust lanes. Nebulae like Orion look spectacular, and with a good filter, you can view the supernova remnant in Cygnus known as the Veil, which stretches across an area of sky 10 times the width of the full Moon. Globular star clusters might look vaguely grainy, but they are beyond the resolving power of a 100mm telescope—albeit barely. Your telescope has a 1.25 inch focuser tube and diagonal - this means that any 1.25" eyepiece (EP) will fit. EPs start at about 20 pounds and go up to over 400 pounds each so you have a very wide choice. There are a lot of good eyepieces at the cheaper end though which will work very well. Prices depend on optical quality and also on design. Extras Red-dot finder, erect image star diagonal, 10mm and 20mm eyepieces, red light LED torch, printed instruction manual

For the most part you can add your smartphone with its case on, but if you have an extra large case you may need to take it off for it to fit the adapter. Additional Accessories

The Popular Science by Celestron StarSense Explorer DX 100AZ uses the same optical tube and includes the same accessories as the Inspire 100AZ, but with an improved alt-azimuth mount that has slow-motion adjustments – further aided by Celestron’s StarSense Explorer technology to make aiming the telescope even easier. If you are considering the Celestron Inspire 100az, then its good to know the features that make a great Refractor. Here are the main three: Aperture: After an initial alignment with the main telescope, the red dot finder proved useful and, again, is an ideal addition for beginners taking their first steps into stargazing – especially if they’re learning how to find objects by star hopping with a star chart and the supplied red flashlight. Includes 1 free year of the “SLOOH Astronomer” subscription. Remotely reserve, control, and image through professional grade telescopes, access to livestream SLOOH shows, and many other featuresWhen it comes to running footwear, you can keep your GTX-lined gear, I’m better off without it – in more ways than one The Celestron Inspire 100AZ is part of the Inspire line of refractors, so named because they are meant to inspire children and so forth, as well as be extremely easy to use. Other than the poor-quality telescopes making up Celestron’s poor-quality bargain lines like the PowerSeeker and AstroMaster series of telescopes, the Inspire refractors are meant to be Celestron’s flagship line of all-manual instruments. They’re a bit unusual in that they neither try to offer purely an aperture-for-price value (as with most reflectors) nor a “professional” appearance like many cheap equatorial or fork-mounted refractors. Focus micrometer provides fast return to a particular focus point for specific targets like bird's nests, infinity focus, etc.

If you need greater eye relief, you will pay a little more. I would go for a 5mm EP which will give slightly higher magnification: http://www.365astronomy.com/5mm-The-Planetary-Eyepiece.html or http://www.365astronomy.com/5mm-BST-Explorer-ED-Eyepiece.html The latter (also marketed under different names including Starguider and Paradigm) is a very popular EP with members of this forum.

OVER 60 YEARS OF INNOVATIVE TECHNOLOGY

Saturn’s rings are easy to spot with the Inspire 100AZ, as is the Cassini Division within them and a few cloud bands on the planet itself, though they are not particularly colourful and appear as purely symmetrical strips. A few of Saturn’s moons can also be seen, with Titan being the brightest among them. Rhea, Tethys, and Dione are easy to spot; Enceladus and Iapetus are tougher.
