Mars Opposition 2020 !!

In less than a month, the "Mars Mission" is about to commence -- Mars Opposition 2020!

At that time,  Mars will be visible with its best situation - the brightest magnitude, and its larger apparent size in the past 20 years and the long visible time. This time, 14 Oct 2020 will be the best moment. Should we wait for the next time or another day?

Smart people like you would not miss out this opportunity! The fun part of amateur astronomy is able to experience such rare astronomical phenomena in person, especially the "Mars Opposition". Uniqueness of Mars is that it takes every 26 months for close observation.  Mars will be in contact with Earth and Sun as a line-up and therefore, it stands a great chance for viewing larger and brighter Red Planet.   In short, Mars is visible all night in its best!

Get yourself and your telescope ready!  When Mars is traveling away, the far-away Mars will be like an acacia bean, red but truly tiny!

For even more fun, Astro Fi’s lens cap does double duty as a smartphone adapter. Position your smartphone inside the adapter and then secure it over the Astro Fi’s eyepiece to capture images and video of all your discoveries.

Do you know how it works? Let's see the frequently asked questions.

1️⃣ Is it connected to our home Wi-Fi to control the telescope?

No, it is not.  It doesn't limit your location - be it at home with home internet connection, or in a suburban area without any signal of internet.  The integrated WiFi module is directly connected to any smart devices with WiFi direct connection.  It does not use any mobile data at all.

2️⃣ Does it come with any physical controller or remote control?

As this is a WiFi-enabled model, therefore it is made to connect with your smart device - either Android or iOS, 9 inch tablet or a smartphone.  Besides, Celestron Hand Control (HC) is a separate sold unit, but compatible with AstroFi series telescope.

3️⃣ Is there any built in rechargeable battery for telescope operating?

There will be no built in battery.  It requires external AC battery, such as 8 pieces of AA battery. Battery pouch is supplied for AA batteries.  Meanwhile, users may find themselves other but compliant AC power source to run the scope.  Please note that AA batteries are not supplied, nor any AC-DC power adapter.

4️⃣ Do I need to pay for the software - Skyportal?

It's total FREE to download and use, from both iOS and Android play store.  If you wish to learn more about the SkyPortal mobile app, please feel free to click more about SkyPortal.

5️⃣ How do I begin the telescope setup?

Before night observation, there are few basic things need to be done: aligning finder scope, adjusting the mount tripod to desired height,  making sure sufficient power supply (AC batteries) and preparation of related accessories.  Then pair your device to your compatible Celestron WiFi telescope.  When your search for external WiFi connection (telescope) with your device, you will be prompted of something like "Celestron xxx"  or "SkyPortal xxx" for connecting action.  Once connected, open up the SkyPortal mobile app and follow the on-screen instructions to perform star alignment or other operation.


SkyAlign Technology

With SkyAlign, setting up and using a computerized telescope is faster and easier than ever before. Point the telescope at three bright objects in the sky, and the telescope tells you what the objects are. You don’t need to know the names of the stars—you can even pick the Moon or bright planets!

SkyAlign is the simplest method to align a computerized telescope, providing ease of use for beginners while retaining the accuracy demanded by experienced users.

Input the date, time, and your location (use your smart device to obtain this information automatically) and then point the telescope at any three bright objects. There is no need to point the telescope north or to level the optical tube as in previous alignment methods: the initial position of the telescope is irrelevant. 

What is Alignment?

You have to know where you are in order to determine where you’re going. That’s what aligning a computerized telescope is all about. The telescope software needs to know the exact orientation of the telescope in relation to the night sky in order to find the tens of thousands of celestial objects programmed in the hand control.

Taking the Guesswork Out of Alignment

Other methods for aligning a computerized telescope require the user to confirm what star the telescope is pointing at in order to align. If you don't know where Arcturus or Sirius is, how can you confirm that information? The best you can do is guess. With SkyAlign, you truly don’t need to know anything about the night sky in order to enjoy it—and it's only available from Celestron.
