Smartphone Astronomy – Reducing white light from the screen

August 21 2020

There is a lot of info on the web about how to do two big things with electronic devices for astronomy. The first is usually about “electronically assisted astronomy”. Local astronomer Jim Thompson was interviewed for the website AstronomyConnect.com and he defined EAA the following way:

…the application of any sort of technological aid for the enhancement of astronomical viewing falls under the EAA umbrella. Devices such as light intensifiers and video cameras both fit into this category. The purpose of the technological aid is either to increase the observable detail over what’s possible with a conventional eyepiece, or in some cases to make it possible for those with vision problems to see anything at all.

In short, it helps you or your equipment see better. Tightly tied to it is the idea of using the electronic devices to actually capture the images for astrophotography.

Stepping back — Smartphone astronomy

Some people like to use their smartphones with their astronomy setup, but not always in those first two big ways. More often than not, they are using smartphones or tablets as simple electronic star maps or reference libraries rather than carrying paper guidebooks. My interests start off with these much simpler needs and go up to and include simple astrophotography.… Read the rest

A quick way to understand the basic steps in smartphone astrophotography

I’ve posted a few times about my experience with smartphone astrophotography. A person who is active online in this area, Kevin Francis, shared with me a copy of an infographic he did based on his experiences.

You can find the infographic over at:

http://kevinrfrancis.com/2018/07/smartphone-astrophotography-6-steps/

Note that the infographic isn`t meant to give you all the details, but I like his framing:

  1. Choosing your equipment (i.e., pick a smartphone);
  2. Choose a camera app (there are only really two great ones, depends on which OS you`re running);
  3. Use a tripod or mount to make it steady;
  4. Decide if you`re using the phone by itself, marrying it to a lens, or shooting through a telescope;
  5. Capture the image (single shots, long or short exposures, multiple images for stacking, etc.);
  6. Process the images you took.

Is that level of detail going to get you going today? No, but it will tell you the basics you need to know so you can start thinking about what you want to do. Thanks to Kevin for sharing…

Articles I Like: How to Take Good Photos of the Moon

November 11 2017

I’m frequently on the lookout for tips and tricks for astrophotography, although my ambitions are a bit basic to start with — smartphone use at the telescope eyepiece for now, maybe graduating to DSLR and webcam stuff later. And some of the easiest of the early photos are for moon shots. So, of course, I clicked when I saw an article on HowToGeeek.com entitled How to Take Good Photos of the Moon (by Harry Guinness, September 13th, 2017).

He breaks the challenge down pretty succinctly: the brightness and the distance. On the technical side, he recommends a tripod (duh), plus a 200mm lens for full-frame and 130mm on a crop-sensor. The tip, and why I thought the article was useful, came with a rule I’ve never heard of — Looney 11.

Astrophotographers have a rule for taking photos of the moon (it’s more of a guideline really) called Looney 11. The idea is that if you set your aperture to f/11, the correct shutter speed will be the reciprocal of the ISO. In other words, if your aperture is set to f/11 and your ISO is set to 100, your shutter speed will be 1/100; if your ISO is 400, the shutter speed is 1/400.
