-At this point we assume you have your mobile device talking to Seestar, and you’re looking at the Home Screen.
+Before we begin, note that the app seems to have been designed with a tablet in mind, so you might try one, if you can.((One major advantage of a tablet is the "joystick" isn't displayed in the center of the screen, exactly where you want to look. It's offset to the right.))

 ====== Scenery Mode ======

+Now, if you’re about to embark on your first session with the Seestar, do it during daylight when you can see what you’re doing.
+Start by selecting the Scenery Mode in the center of the Home Screen.

-Start by selecting the Scenery Mode on the Home Screen. If you're using a phone, it'll be hiding out of sight over there on the far right end of the Stargazing, Solar, Lunar, Planetary, Scenery row (under the weather forecast). The app seems to have been designed with a tablet in mind, so you might try it, if you hav one.((One major advantage of a tablet is the "joystick isn't displayed in the center of the screen, exactly where you want to look. It's offset to the right.))
+On the right side of the screen you see three dots at the top. Tap that and you'll see a little control panel pop-up with a white slider dot named MF, which stands for Manual Focus. Drag the slider to the right and the manual focus panel will appear on the left side of the screen.{{:screenshot_2024-12-26_at_6.25.02 am.png?nolink&200 |}} It will stay there from now on, even if you leave the scenery mode.
+Below the MF slider is a button labeled Tutorial, tap that and you'll see a nice explanation of what all the buttons on the right do.
-In the center of the Scenery screen, if you tap it, is a little white circle that turns into what amounts to a “joystick” that you control by sliding your finger on the screen. It has a Slow and Fast mode both of which are, frankly, frustrating because they aren’t very precise.  {{:joystick.png?nolink&100 |}}And when you return the “joystick” to the center, the scope keeps going and overruns what you wanted to look at. It is especially bad in the Fast mode. But with a little practice you’ll get the hang of it.

But with a little practice you’ll get the hang of it.
-Slide the joystick up on the screen and the Seestar arm with the scope in it (known as the OTA or Optical Tube Assembly) will start to elevate in altitude up toward horizontal. Move the joystick left and right and you’ll see the Seestar slew in azimuth. Now practice by trying to center distant targets and fiddle with the focus so you learn how it works.
+Slide the joystick up on the screen and the Seestar arm with the scope in it (known as the OTA or Optical Tube Assembly) will elevate in altitude. Move the joystick left and right and you’ll see the Seestar slew in azimuth((Now you know why it's called an alt/az telescope)). Practice by centering distant targets and fiddle with the focus so you learn how that works. Terrestrial objects are closer than galaxies and nebulae (duh) so you'll always have to refocus in Scenery Mode because the scope automatically goes to the default focus number (the number between the focus arrows) set at the factory. ((You can change that in the Settings if you discover it's not quite right when shooting celestial objects.))
-If you happen to be in a location where distant objects move slowly such as ducks on a lake or boats on the ocean the Seestar will track them if you tap the square with a dot in it and then draw a line across the object you want to track. The Seestar will put a box around it, move it to the center of the screen, and then keep it there. It’s not the most reliable and is easily confused by objects in the foreground and background or low contrast. But when it works, it’s fun to use to make a movie or timelapse.

 ===== Sun =====
-Now, tap the solar icon on the Solar System Screen, and insert the solar filter as directed. Once you install the solar filter, click the Go Gazing button and level the scope if necessary, the scope will find the Sun. Patience, it takes a while—you may even see the Sun flash across the screen as it hunts for it.((Avoid large metal objects such as a car because it will confuse the Seestar's compass.))

-If the Seestar doesn't located the Sun, use the crack between the OTA and the base as an aiming sight and point the scope using the joystick just a little to the left of the Sun. To avoid looking at the Sun, just watch the shadow on the ground or hold your hand behind the scope. When the crack appears as a light line in the shadow, point the scope a little left. Now tell it to GoTo the Sun again. If //that// doesn't work, try maneuvering the scope your self to find the Sun. You'll know you're close because the edge of the screen will get brighter. If it gets darker you're going the wrong way.

 If you point the scope directly at the Sun without the filter it will turn your Seestar into an expensive paperweight.
-That applies to taking the filter off, too. In your mind you’re going to shut down or go to some other target, but the scope will still be pointed directly at the sun. So be sure to slew the scope away from the Sun before you take the filter off.</WRAP>

-Both the Sun and Moon Modes have 2x and 4x enlargement (not zoom) buttons, so you can have some fun looking at Sunspots and craters. The buttons will select a small portion of the image and display it full screen like this 2X view. DSLR folks refer to it as digital zoom so you’re forgiven if you think there is some actual zoom involved. But nothing in the optical path changes in the Seestar (or DSLRs). You’re looking at the same data, just displayed larger.

-Imaging in Planetary Mode is a little different because the planets appear tiny thanks to the short focal length (250mm) of the Seestar, and because they’re very bright spots in the black night sky.

-If you tap the image of any planet, the Sun, or the Moon you’ll get a nice description and some details. Scroll down and you’ll see a handy chart that shows what time the planet is visible from your location and it’s current altitude and azimuth so you'll know if it’s going to be behind that tree or not before you waste time asking Seestar to find it. The white dot graphically shows you what the current time is and the line shows what the planet’s altitude will be when it’s above the horizon. Drag the dot and it will show altitude, but reported Alt and Az values don’t change, which would be more useful.

Tap the oddly named Gazing button (maybe Observe or Imaging would be better?), you’ll be shown the planets location on the sky map, the scope will slew to its location, and it will go through its plate solving routine to put the planet in the center of the screen.
+The Seestar won’t slew to a solar system object unless you press the Go Gazing button at the bottom of the screen.
-Left to its own devices, the Seestar will expose for the dark background and completely blow out (over expose) the planet, obliterating the dark bands and light zones on Jupiter, the rings of Saturn, and frost on the pole of Mars. Fiddle with the exposure and gain (the circle with the + and - in it) and you'll be able to turn down the brightness and see some details.

 If you zoom out using the minus button while it’s slewing you’ll see a blue rectangle (where your scope is pointed) moving toward the red rectangle (your target).

 In essence, Seestar's DSO Mode (er, Stargazing Mode) takes care of the technical aspects of capturing astroimages((To be pedantic, what the Seestar does is not astrophotography, it's astroimaging. No photographic process using silver halide is involved. But this isn’t a battle worth fighting because common usage always wins. That’s why we call the event each evening //sunset// not //earthrise// even though we’ve known for 800 years the Sun isn’t rotating around the Earth.)), allowing you to focus on enjoying and sharing the lovely images of deep-sky objects you and Seestar produce.
+=====Sky Atlas=====
+The Seestar Sky Atlas is a comprehensive star map feature integrated into the Seestar mobile app for both Android and iOS devices. It includes an extensive database of celestial objects and provides a "tonight's best" list of recommended targets to observe.

+==== Key Features ====
+The red target frame can be moved to a target and blue pointing frame will GoTo
+Searchable collection of deep-sky objects such as emission and reflection nebulae, supernova remnants, and globular clusters
+Features
+  * GoTo with plate-solving accuracy
+  * Recommends optimal targets for viewing each night
+  * Live sky compass allows you to point mobile device at a target and the GoTo
+  * Framing mode lets you select an area up to 2x and rotate the frame for optimum composition of a mosaic
+While Sky Atlas is great for controlling the telescope, some users have found ways to use third-party software like SkySafari for additional object database access.
