Now with GPS based declination calculation!
By importing the images and perform the photo stacking steps without bringing a laptop.
The application will stack up all JPGs in the selected folder and save the resultant as the file name "result.jpg" or the name you choose in the same folder.
It requires large memory size for the apps to process 12-mega pixels images stacking.
Testing images is done by maximum images size from an EOS6D shooting with a microsd and processed by a Sony xperia Z handset. Time for stacking 600 photos approx. > 3000 seconds and may need 10% of the battery for the processing.
I make this apps for my trips as I would like to shoot some star trails photos but not to bring up a laptop as the camera was already a heavy stuff which take cost when traveling in plane. And I just think if there are guys would like to shoot for star trails considering to bring less equipments and share the star trails immediately after shooting just like me, so I share this apps.

Ansel Adams dedicates the beginning of his first book "Taos Pueblo" to visualization. He introduced the idea of "previsualization", which involved the photographer imagining what he wanted his final print to look like before he even took the shot. Of course there are many great photos which were taken impromptu. However, for landscape photographers, being able to previsualize the scene before going there will greatly reduce the chance of being caught unprepared and will greatly increase the chance of getting better shots.
Photographers use various tools to help them pre-visualizing the scene. Nowadays, many of those tools are phone apps. PlanIt! is all-in-one solution that is designed to leverage the map and simulated viewfinder technologies (VR, AR etc.) to provide the necessary tools for photographers to pre-visualize the scene in combination with the Sun, Moon, Stars and Milky Way. Some questions that you might ask yourself before going out for a photographing trip are:
* Where is the Sun or the Moon at the time and the location and to see the animation of the Sun/Moon/Stars/Milky Way movements as in real?
* When and which azimuth is the Sunset or Sunrise today or on any date at any location around the world?
* Where should I go to get a nice view of the scene and possible compositions?
* Do I get a clear view of subject from a certain location where is no mountain blocking the view?
* What lens should I bring in order to capture the whole width or the height of the scene?
* If the scene is too wide, how many shots do I need to take to create a panorama and how many angle should each shot cover and how many angle should I rotate the camera between each shot?
* How do I compose the scene considering the subject’s elevation and the sun or moon location?
* Is tonight a good time for star trail photography? How long can I exposure without being affected the rising moon? Where should I aim at the sky to get the Polaris at the center?
* What are the dates and times to have Milky Way at certain position on the sky?
If you are interested in the answers of any questions above, the PlanIt! is the right app for you. In a simple app, we included Tools feature for you which allow you to find out GPS coordinates, elevation, distance, elevation gain, direct view, focal length, depth of field (DoF), hyperfocal distance and panorama, and all of those are represented to you visually on the map and sometimes in a simulated viewfinder. In addition, the Ephemeris features include the sunrise, sunset, moonrise, moonset time and location, twilights, special hours of the day, position of the Sun and the Moon, Sun/Moon Finder, more than 100 stars (such as Polaris) azimuth and elevation angle, star trail planning and exposure time calculation, time-lapse and hyperlapse calculation, milky way searching, exposure/ND calculator, light meter, bub timer etc. Again, all of them are either represented on the map or in the viewfinder. You can even use existing pictures in the viewfinder to explore with new photographing ideas.

A number of details increase or decrease the requirement for precision. Factors that require higher precision include: longer exposure duration, increased distance between the guide star and the edge of the imaging field, and declinations that approach the pole. Factors that tolerate more error include: shorter duration exposure, centering of the guide star and a smaller imaging field, and declinations that approach the equator.
Drift polar alignment via a guide camera and guide scope allows a precise measurement of the rate of movement of a guide star. By using tools to measure the drift rate during ALTITUDE and AZIMUTH adjustment phases of the drift procedure, a value of error can be calculated. Some drift alignment tools report this error in pixels or arc seconds.
After entering the values in the Imaging setup parameters menu, then entering the values of Declination and Exposure Duration on the main screen, the maximum allowable error is displayed. During drift alignment, the speed star movement should be recorded and entered as Measured Drift to determine current conditions.
Note: You can tap the parameter's description on the main screen to see a more detailed explanation for the corresponding value.
This tool allows an astrophotographer to better understand the limits of their setup, so that they can determine if a configuration is feasible.

What is the Universe?
All existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.
Facts about our solar system:
1. Our solar system is made up of the sun and everything that travels around it. This includes eight planets and their natural satellites such as Earth's moon; dwarf planets such as Pluto and Ceres; asteroids; comets and meteoroids
2. The sun is the center of our solar system. It contains almost all of the mass in our solar system and exerts a tremendous gravitational pull on planets and other bodies.
3. Our solar system formed about 4.6 billion years ago.
4. The four planets closest to the Sun - Mercury, Venus, Earth, and Mars - are called the terrestrial planets because they have solid, rocky surfaces.
5. Two of the outer planets beyond the orbit of Mars - Jupiter and Saturn - are known as gas giants; the more distant Uranus and Neptune are called ice giants.
6. Most of the known dwarf planets exist in an icy zone beyond Neptune called the Kuiper Belt, which is also the point of origin for many comets.
7. Many objects in our solar system have atmospheres, including planets, some dwarf planets and even a couple moons.
8. Our solar system is located in the Orion Arm of the Milky Way Galaxy. There are most likely billions of other solar systems in our galaxy. And there are billions of galaxies in the universe.
9. We measure distances in our solar system by Astronomical Units (AU). One AU is equal to the distance between the sun and the Earth, which is about 150 million km (93 million miles).
10. NASA's twin Voyager 1 and Voyager 2 spacecraft are the first spacecraft to explore the outer reaches of our solar system.
