Using a Sigma 24mm F/1.4 for Astrophotography November 21, 2020
The Sigma 24mm F/1.4 lens is an interesting choice for astrophotography, particularly wide-angle Milky Way photography. With an f-ratio of F/1.4, this Sigma art series lens can pull in a lot of light under a dark night sky. Over the years I have used a number of great camera lenses for astrophotography from the Rokinon […]

The Radian Raptor 61 is a triplet apochromatic refractor telescope for astrophotography. It features a compact design with features custom-suited for wide-field, deep-sky astrophotography. Since the Raptor arrived in September, I have taken some of my best astrophotography images to date with it. In this review, I'll share all of the image examples I have […]

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 […]

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 […]
