- ZWO ASI585MM Pro Review: An Affordable Mono Powerhouse June 19, 2025The ZWO ASI585MM Pro is ZWO’s most affordable cooled monochrome astronomy camera, and after two months of backyard imaging with it, I’ve come away pretty impressed. This little camera offers a lot of versatility—ideal for both planetary imaging and deep-sky astrophotography—thanks to its high frame rate and cooling capability. But like any gear, it has...

- I Ran An Image Processing Challenge, The Results Humbled Me May 23, 2025I recently ran an impromptu astrophotography image processing challenge, and the results were out of this world (sorry, I had to do it). The craziest thing about it is that the data wasn’t overly great (in terms of overall exposure time) or interesting. Just a seemingly random portion of the constellation Cygnus that includes the...

- Markarian's Chain in Virgo April 13, 2018My 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 […]Phil
- M51 Whirlpool Galaxy April 9, 2018A 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 […]Phil
