In this video I take a look at the Optolong L-Pro light pollution suppression filter for city backyard astrophotography with your telescope and DSLR or cooled cmos camera. I also do a quick process in Pixinsight of the data taken with the L-Pro filter and show you the end result which is quite stunning considering the short amount of time I spent imaging M31 and it was taken in bortle 7/8 sky.

What is this filter though and how does it work? Why do you need it?
If you’re part of the growing number of astrophotographers that are imaging from their own astro backyard, then you’ll be dealing with city street lights and neighbour outdoor lights in addition to cloudy nights! So for those few clear nights we get, we want to make the most of it and the Optolong L-Pro filter can really help.
It’s designed to work with one shot colour cameras, which includes DSLR and cooled cmos.
If we look at the spectrum chart we can see how the L-pro filter works and the specific wavelengths it tunes in and out. It’s quite a detailed spectrum chart and Optolong has done some good work in making this filter a reality. I always appreciate companies developing new technologies for the astrophotography community – to help make our images even better. With light pollution spreading and growing by more than 2% a year globally filters like the L-pro filter are very much welcomed additions to my astro gear and maybe yours as well.
I got a fabulous result using the L-pro filter on my Esprit 100 triplet refractor and with a QHy168C cooled cmos camera. Check out my video below for more on this…
My story began more than 40 years ago looking up at the Moon with a small collapsible telescope my Father had. Encouraged by my parents, who bought me my very own telescope, a 4.5″ reflector, I began to explore the night sky from my family home backyard. Today I do astrophotography from my home in Kitchener, Ontario and also with remote telescopes located in New Mexico and Australia. Some of my images have won awards and have been featured online and in magazines.
