Canon EOS Ra Review January 7, 2020
In late December 2019, Canon USA reached out to me to test their new astrophotography camera, the Canon EOS Ra. The "a" in the name of this camera stands for astrophotography. That is because, unlike the regular Canon EOS R, this camera is 4X more sensitive to the h-alpha wavelength of the visible spectrum (656.3 […]

Building a Deep Sky Astrophotography Kit December 21, 2019
I am often asked for my opinion on the best route to take when it comes to building a deep-sky astrophotography kit for the first time. A popular option for many night sky enthusiasts is to start with a DSLR camera and telescope, and I can understand why. Building an astrophotography setup that revolves around […]

Markarian's Chain in Virgo April 13, 2018
My own Hubble View! These galaxies lie between 10 to 50 million light years away. How many galaxies do you see?A pretty tricky part of the sky to image, really. You're utilizing almost your entire field of view with an 80mm scope, so dealing with all that comes with wide-field. This is the best iteration […]

M51 Whirlpool Galaxy April 9, 2018
A nice clear night last night until around 12:30 when clouds rolled in. Managed to get this image of the lovely M51 Whirlpool galaxy. It lies around 23 million light years away and it is interacting with a smaller galaxy (yellow~ish bulge to the left). Three supernova (star explosions) have been detected in this galaxy […]

M81 and M82 March 15, 2018
The spring brings out some great galaxies. This is the first iteration of a long-term project I'll be working on with respect to these two galaxies.M81 is on the right, lies around 11.7 million light years away and harbors around 250 billion stars. M82, on the left, is also called the "Cigar Galaxy" lies at […]
