More About the Celestron NexStar Evolution 9.25 Telescope

Celestron’s signature telescopes reach a new level with the NexStar Evolution! It is the first Schmidt-Cassegrain telescope with integrated WiFi so you can leave your hand control behind and slew to all the best celestial objects with a tap of your smartphone or tablet. Connect your device to NexStar Evolution’s built-in wireless network, and explore the universe with the Celestron mobile app for iOS and Android.

Use the planetarium interface to view the night sky in real time or display a list of celestial objects currently visible based on your time and location. The proprietary SkyAlign alignment procedure is built right into the Celestron mobile app, so you’re ready to observe within minutes.

NexStar Evolution – the Most User Friendly Telescope Ever!

Celestron engineers designed the NexStar Evolution based on years of customer feedback. It offers many thoughtful design features that combine to provide you the best possible experience out under the stars. Forget about batteries or an external power supply. For the first time ever on a consumer telescope, NexStar Evolution includes its own built-in lithium-ion battery so that you will be able to enjoy stargazing marathons of up to 10 hours on a single charge! You can even use NexStar Evolution’s USB charge port to top off the other devices in your life that need to stay powered on during an observing session.

Setting up your NexStar Evolution is quick and painless with large, ergonomic handles. The steel tripod features leg etchings to help you achieve a level, uniform height for your telescope. Manual clutches in both altitude and azimuth offer greater flexibility to manually point the telescope when powered off. Store up to 7 eyepieces in 2 accessory trays, one with an adjustable red LED illuminator.

Enjoy Superior Tracking While Astro-Imaging!

If you’re interested in astro-imaging, the Celestron 9.25” NexStar Evolution is an excellent, affordable way to get started. It’s the only fork-mounted telescope in its price range that offers worm gears, along with improved motors. NexStar Evolution’s tracking accuracy is so impressive, you can capture images of deep-sky objects like the Orion Nebula by simply attaching your DSLR camera. As you progress in the hobby of astronomical imaging, you can add the Celestron Pro HD Wedge to achieve longer exposures for more detailed astrophotos.

Of course, the 9-1/4” Schmidt-Cassegrain optical system offers bright, sharp views with StarBright XLT optical coatings—a great choice for visual observers and budding astroimagers alike.

The 9.25” NexStar Evolution includes the OTA, single fork arm mount and tripod, accessory tray, hand controller, 40 mm and 13 mm eyepieces, red dot finderscope, visual back, star diagonal, and a 4-plug AC adapter.

About the Apertura Red LED Flashlight…

Keep your eyes dark-adapted during any activity at night with this mini red flashlight from Apertura!  Amateur astronomers go to a lot of trouble to keep their skies as dark as possible, from turning off porch lights to driving out of the city in search of  pristinely dark skies.  It takes about a half-hour for your eyes to truly adapt to the dark, and once that happens you will be able to see more detail and much fainter objects.  Don’t ruin that dark adaptation by turning on a white flashlight to find an accessory or read a star chart!  When you use the Apertura Red Flashlight instead, your eyes will not react near as much as they do to white light, and they will stay dark-adapted.  Think of how much easier it is to see objects in the bedroom after the lights have been off for awhile.  Turning the light off let’s your eyes adapt to the dark so you can see better.  In the same way, not using white light (and getting away from sources of light as much as you can) lets your eyes adapt to the dark and lets you see more stars, galaxies, nebulae…more celestial objects, and that is the name of the game when it comes to astronomy, right?

By the way, if you use a computer or your smartphone, you can buy rubylith film at an art store to make red covers for the screens.  Also use smaller pieces to cover the interior lights of your car!  It may not be perfect, but it will help quite a bit in the fight against white light!

This red flashlight is short enough to fit easily in most astronomy accessory cases, your glove compartment, backpack, computer bag or purse.

About the Apertura Moon Filter…

The Moon is bright and this Moon Filter is just the thing for more comfortable (and rewarding!) viewing. It’s like putting sunglasses on your telescope eyepiece! To use, simply thread onto the barrel of any 1.25″ eyepiece or Barlow lens and then insert into the focuser or diagonal as usual. You will be amazed at how lunar features, such as craters big and small, maria, and mountains come into view when your eyes are not overpowered by the moon’s brightness. This Moon Filter works well for Venus as well!

The Apertura moon filter has been produced with high grade optical glass and is anti-reflection coated to prevent glaring and ghosting. For the price, you can’t beat this filter as it should be a staple in any astronomy filter collection.

About the Apertura Lens Cleaning Pen…

The Apertura Lens Pen is just the tool you need to do a quick cleaning job on all of your smaller optics! Use the retractable brush to gently remove dust and any other loose particles. That may be all the cleaning your small telescope, binoculars, camera lenses, or eyepieces need, but if there is still some smudges, use the other end of the Apertura Lens Pen to gently remove them. The special non-liquid cleaning element is designed to be gentle yet effective and will never dry out.

Whenever the Apertura Lens Pen is not in use, make sure to retract the cleaning brush and use the cap. This Lens Pen is so portable; you can keep It in your camera bag or astronomy accessory case so it will always be available when you need it. Remember, only clean your optics when you have to! A few specks of dust is normal and won’t usually interfere with your observations. If you do need to clean, always choose the tool with the least impact on the surface of the glass first. Taking care to only clean your optics when absolutely necessary will help keep the coatings intact and scratch-free.
