Deepsky astrophotography with and without a narrowband filter

City lights, neighbours outside lights, limited number of clear nights and astrophotography from your backyard, all mean having to battle not only light pollution but time and opportunity to engage in our hobby. So if there’s technology that can make things a little easier than why not give it a try! Narrowband and light pollution […]

A new city light pollution filter! Triad Quadband Ultra Filter.

The Triad Quadband Ultra Filter from OPT is both amazing and fun to use. For many amateur astronomers and astrophotographers, light pollution makes things difficult and in some cases impossible when it comes to imaging the night sky. All is not lost though. For those astrophotographers using a one-shot-colour (OSC) DSLR or cooled cmos camera […]

M31 90min LRGB test using ASI1600mm-cooled CMOS camera

M31 90min LRGB test image with ASI1600mm-cooled

I performed some more test imaging with the ASI1600mm-cooled camera. This time I centered the telescope and camera on M31, the great Andromeda galaxy. I have imaged M31 before a few years ago using different equipment. This galaxy is a popular target at this time in the northern hemisphere when it rises high in the […]

Elephants Trunk Nebula in narrowband H-alpha

Ic 1396 Elephants Trunk Nebula in Hydrogen Alpha narrowband astrophotography. Shawn Nielsen 2014

Another image taken in July 2014. This time I was collecting narrowband Ha (H-alpha) data on the Elephants Trunk Nebula within the larger emission nebula region of IC 1396. I feel the most extraordinary thing about this image is that it was taken from within a regional area consisting of 3 cities (population of 500,000), […]
