51630 StarPointer Finderscope by Celestron

The Celestron Star Pointer Finderscope is the way to go if you want the easiest way possible to locate an object and center it in your eyepiece.

A red dot finder, unlike an optical finder, has 1x magnification, displays a super wide field of view, and keeps the sky right side up and left-to-right correct, matching what you see with your unaided eyes. An LED creates a red dot, superimposed on a viewing screen, so you simply point the Star Pointer to the area or object you wish to observe, look through your eyepiece, and if properly aligned, the area in and around place you pointed the red dot will be centered in the field of view.

If you like the idea of having some magnification, try installing both a red dot and optical finder on your telescope. Schmidt-Cassegrain and EdgeHD telescopes have multiple mounting bracket holes so you can get the best of both worlds. Just make sure to align both of them correctly, and you ll get the best use out of each of your finders.

• The Star Pointer Finderscope adds "point & look" functionality to any telescope!
• This red dot finder keeps the sky right-side up, matching what you see with your unaided eyes.
• The adjustable red dot is bright enough to see day or night.
• Attaches to just about any telescope thanks to the small footprint, even works great with astronomical binoculars and spotting scopes.
• Includes mounting base and a long-lasting CR2032 3V battery.

How to Align the Star Pointer Finderscope

The first time you use your finder, you need to align it. This one-time setup procedure should be done during the day. Take the telescope outside and find an easily recognizable object, such as a streetlight, car license plate, or tall tree. The object should be as far away as possible, but at least a quarter mile away. Move the telescope left and right or up and down so that it is roughly pointing at the object. Look through the telescope using your low power eyepiece and move the telescope until the object you chose lies in the center of the view. Once the object is centered in your eyepiece, turn on the red dot. With your head positioned about a foot behind the finder, look through the round lens of the finder and locate the red dot. Without moving the telescope, use the two adjustment knobs located on the side and underneath the finder. One controls the left-right motion of the dot. The other controls the up-down motion of the dot. Adjust both of these until the red dot appears over the same object you are observing in the eyepiece.

Your finder is now aligned and should not require realignment unless it is bumped or dropped. You can even take the finder off the telescope and reattach it while preserving alignment.

81037 Smartphone Adapter DX Kit, 1.25" by Celestron

The Smartphone Adapter DX Kit is a great first step into the world of astroimaging or digiscoping. You get everything you need to capture sharp, detailed images and video: the smartphone adapter and a Bluetooth shutter release remote. Snap an Instagram-worthy image of the Moon, share your latest wildlife sightings with a binocular or spotting scope, or preserve lab specimens from your microscope—this versatile adapter handles it all with ease.

The Smartphone Adapter fits any eyepiece from 29mm to 45mm in diameter, including telescopes equipped with 1.25" eyepieces, spotting scopes, monoculars, and binoculars.

The Smartphone Adapter DX Kit accommodates a wide range of smartphones. The phone platform adjusts and can fit any device—usually with the case still on. The secure platform stands up to the weight thanks to the adapter's strong threaded knobs to secure the adapter in place.

No matter which optic you choose, installing and using the adapter is hassle-free. First, place your phone in the adapter. It's held securely in position with the help of a tightening knob that locks your phone in place. Next, align the phone's camera with the center of the eyepiece. Once you've determined the perfect position, tighten the adjustment knob for a secure fit.

Note: Some large and/or bulky phone cases (including folio style cases) may need to be removed for the phone to fit in the adapter.

Once the phone is mounted over the eyepiece, you can capture still images or video, plus access all the rest of your phone's features. You can even text your photos to a friend or post them on social media while your phone is still mounted in the adapter.

To determine if your optic is compatible with the Smartphone Adapter, simply measure the outside diameter of your eyepiece. If it falls within the 29mm to 45mm range, you may use it with this adapter. The adapter does not work with riflescopes.

Bluetooth Shutter Release Remote

To capture the best image, Celestron has also provided a Bluetooth shutter release remote that allows you to trigger the camera's shutter on any Android or iOS smartphone. The remote reduces the blurriness in your images caused by the phone or telescope being disturbed. Instructions on how to pair your Bluetooth remote to your phone can be found in our quick setup guide.

• A complete digiscoping solution: Smartphone adapter connects your smartphone to an eyepiece while the Bluetooth shutter release button helps you get a steady shot every time.
• Works with telescopes (with most 1.25" eyepieces), spotting scopes, binoculars, monoculars, and microscopes.
• Connect the remote shutter release to your phone via Bluetooth to take photos or start/stop video recording without unwanted vibration.
• Both devices work with virtually all smartphone models, including the latest devices from Apple, Samsung, and Google.
• Simple to use smartphone adapter! Place your phone in the adapter, center your phone's camera over the eyepiece, and use the knobs to secure the adapter in place.
• Durable, metal bodied adapter stands up to rigorous use in the field and harsh weather conditions.

94256 USB Cooling Fan for Dobsonian Telescopes by Celestron

The Celestron USB Cooling Fan is the ideal cooling solution for your StarSense Exploerer 10" and 12" Dobsonian telescope. For those who can't wait to observe, this handy accessory cools the primary mirror to the ambient outdoor temperature faster. The result is crisper, better-focused views sooner – and more time for you to observe.

This cooling fan mounts directly onto the rear cell of the StarSense Explorer 10" and 12" Dobsonian and works with any USB power source (portable power banks, AC wall adapters, and more). Once the primary mirror has cooled down and you are ready to observe, you can disconnect the fan's USB power source. Connect the cable to the integrated storage clip to stay organized.

Powering the Cooling Fan

Any USB power source can charge the cooling fan. Unlike other fans on the market, this USB Cooling Fan for Dobsonian Telescopes does not require an external, bulky 12V power source or disposable batteries. This fan uses less voltage (5V vs. 12V) than competing models. Still, our rigorous internal testing shows that the Celestron Cooling Fan provides better airflow and faster overall cooling compared to competitors.

Compatible Telescopes

The USB Cooling Fan for Dobsonian Telescopes is compatible with the StarSense Explorer 10" and 12" Dobsonian telescope and many other third-party Dobsonians and Newtonian Reflectors that have a compatible fan mount (four M4 x 0.7 threaded holes in a square pattern with holes spaced 71.5mm apart).
