This is Canon's latest astrophotography camera, and it has some seriously impressive specs (like a full-frame 30.3 MP astro-modified sensor). For a complete rundown of the Canon EOS Ra, you can read my full review from January of this […]

Selective Color Boosting (Photoshop Tutorial) May 1, 2020
In this astrophotography image processing tutorial, I will explain an easy way to selectively boost the colors in your image. I like to call the technique "selective color boosting". Increasing the saturation of your deep-sky object can bring out the true beauty of your subject, and better showcase the contrasting elements of the nebula or […]

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 […]

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 […]
