Have you ever walked around your neighborhood at night and noticed the amount of wasted, and oftentimes unnecessary, artificial light? I think we have all noticed the poorly designed outdoor lighting in our neighborhoods that contributes to light pollution. According to the International Dark-sky Association (IDA), light pollution is increasing at two times the rate…
Have you ever looked at a brightly lit building or street light in your neighborhood and thought it was excessive? You know, light shining in all directions or perhaps in your bedroom window, rather than only lighting up the intended area. That is light pollution. Light pollution is misdirected excess/obtrusive outdoor artificial light in a…
If you shoot your astrophotography images with a color camera in the city, there is a good chance that light pollution filters can make your life a little easier. How? By ignoring specific wavelengths of light in the visible spectrum associated with artificial light sources such as a street lamp. The best way to test…
If you’ve been following AstroBackyard on YouTube, you’ll know that I regularly shoot DSLR astrophotography images under the heavily light-polluted skies at home. My night sky is classified as Bortle Class 8 in terms of sky quality, a white zone on the light pollution map. This certainly makes things more difficult in terms of collecting data…
One of the most common questions I receive each day is which light pollution filter I recommend for astrophotography in the city. There have never been so many choices available, with each one offering their own advantages and disadvantages. Couple that with the fact that these astrophotography filters can be expensive, and you’ve got some…
Twilight refers to the period of time when the sun is below the horizon where scattered sunlight illuminates the atmosphere.

You’ll be able to see the exact camera settings I use, and any additional accessories needed…
Backyard Astrophotography Summer would not be complete without spending a night enjoying the dazzling beauty that is the constellation Sagittarius. The “teapot” asterism just clears my fence to the south of my backyard in central St. Catharines. From my latitude, August is my last chance to image the many star clusters and nebulae that populate…
The Texas Star Party is held annually at Prude Ranch in the Davis Mountains during the new moon in May. The 3,500-acre ranch sits at 5,000 feet elevation and is located six miles northwest of Fort Davis, and only 12 miles (19 km) from the McDonald Observatory. It started in 1979 as a weekend event…
You have completed the research and purchased your first telescope and now you’re wondering how to use this new piece of astronomy equipment. You’re ready to look at the moon and planets up close for the first time, and can’t wait to show your friends and family the Rings of Saturn. As a beginner, you…
In this beginner-friendly image processing tutorial, we will use Adobe Photoshop to take an astrophotography image from its raw state to a finished master file for sharing. The post-processing stage of astrophotography is an exciting experience because it is when you finally get to enjoy the deep-sky object you have captured, up-close. This is a…
As an amateur astrophotographer or astronomer, there is a good chance you first started exploring the night sky in your backyard. The backyard is where I spend the most time under the stars, and my first experiences exploring the night sky with a telescope happened there. Your backyard may not be the ideal place for…
