Further in to Smartphone Astrophotography





     In my previous post, I discussed the fundamental aspects of Smartphone Astrophotography. In this article, I would like to share some personal tips and tricks that I have learned from my experience to make things easier.

Before we dive into the tips, let's have a quick recap of the basics. If you are not familiar with them, you can check out my previous article titled "Astrophotography using Smartphones," where I covered topics such as using the Professional mode and various settings to use in different scenarios.

Now that we know how to use our phone to capture the night sky let's talk about how to locate the objects we need to capture and when to capture them. To do this, you can use a Star tracking app from the Play Store or the App Store. These apps track your location and show you all the stars, planets, galaxies, and even satellites above you in real-time. If your phone has a gyroscope sensor, you can point it to the sky and see all those objects in the direction it's pointing. Even if it doesn't, you can still get a good idea of their location by observing the direction and the sky map. My personal favorite is an app called "Star Walk 2" because of its user-friendly interface and a wide range of features. Some of its features are behind a paywall, but they are not expensive, and they are one-time payments. Moreover, you can track the location of objects into the future, making it easier for you to plan ahead. The app also features an astronomy calendar, a notification system that informs you of future events, an Augmented Reality mode, and much more.

Another useful tool is a light pollution map, which indicates the areas where there is excessive artificial lighting and where there is not. The less light pollution, the better, as it can obscure the stars. So relocate to a location with minimal light pollution and elevated to capture a wide area of the sky without obstructions from trees and buildings.

When it comes to editing, there are no techniques specific to astrophotography. You can edit it like any other photo, just play around with the settings. You will need to adjust color curves to draw in the desired colors or realistic colors as some astrophotos end up looking muted and to draw out hidden details. Personally, I recommend Adobe Lightroom, but it's not the only.

Now, let's discuss some common mistakes to avoid. Turn off notifications on your phone, and set your phone to mute, as the vibration can cause the phone to move during the exposure time. Be sure to turn off the flash. If you want something in the foreground to be lit, use a separate light source indirectly, but only for a short time, like a second, and don't use astrong light to avoid overexposing.

These tips and tricks are based on my personal experience of experimenting with different apps and settings and learning from my mistakes. The more experience you gain, the more you understand and become better at it. So, keep playing around with different settings, and soon you'll be making guides like this.

Linear Time and Its Paradoxes

Time is one of the most fundamental aspects of our experience, but also one of the most mysterious and controversial. How do we understand time? Is it a fixed and objective reality, or a subjective and relative construct? Is time travel possible, and if so, what are the implications for causality and free will? In this article, we will explore the concept of linear time and its paradoxes, and explain why it is unlikely to be true. What is Linear Time? Linear time is the idea that time has a beginning and an end, and that it flows in one direction from past to future. This view of time is influenced by the Christian worldview, which posits that time was created by God at the moment of Genesis, and that it will end at the Last Judgement. Linear time implies that there is a clear distinction between past, present and future, and that events are ordered by their temporal sequence. Linear time is also compatible with some scientific theories, such as the Big Bang model of cosmology, which s...

Warp Drive: A Scientific Possibility or a Science Fiction Fantasy?

Warp drive is a term that refers to a hypothetical propulsion system that would allow a spacecraft to travel faster than light. The concept of warp drive has been popularized by many science fiction works, especially the Star Trek series, but is it possible in reality? What is warp drive and how does it work? Warp drive is based on the idea of distorting or warping the space-time continuum around a spacecraft, creating a bubble of space that moves faster than light relative to the rest of space. The spacecraft itself would not move faster than light within the bubble, but would appear to do so from an external observer's perspective. The idea of warp drive is inspired by Einstein's theory of general relativity, which describes how gravity affects space and time. According to this theory, massive objects like stars and planets can bend or curve space-time around them, creating gravitational fields. Similarly, a warp drive would manipulate space-time by using some form of exotic ...

CRISPR-Cas9: A Revolutionary Tool for Gene Editing

CRISPR-Cas9 is a powerful technology that allows scientists to make precise changes in the DNA of living cells. It has been hailed as a breakthrough that could transform medicine, agriculture, biotechnology and many other fields. In this article, we will explore what CRISPR-Cas9 is, how it works, and what are some of its current and potential applications. What is CRISPR-Cas9? CRISPR-Cas9 stands for Clustered Regularly Interspaced Short Palindromic Repeats and CRISPR-associated protein 9. It is a system that was originally discovered in bacteria as a defense mechanism against viruses. Bacteria store fragments of viral DNA in their genomes, called CRISPRs, and use them as guides to recognize and cut invading viral DNA with the help of an enzyme called Cas9. Scientists have adapted this system to edit any DNA sequence of interest by designing synthetic CRISPRs that match the target DNA and delivering them along with Cas9 into cells. How does CRISPR-Cas9 work? CRISPR-Cas9 works by creatin...
