    NGC 3293 Gem Cluster and Neighbors in Narrowband Foraxx Palette with RGB Stars

    Was notified a couple of days ago that this will be APOD for May 1 ! Now I'm convinced the first 2 maybe weren't flukes 😂 NGC 3293 is an Open Cluster consisting of more than 100 stars brighter than magnitude 14 and within some impressive surrounding Ha nebulosity. This cluster which is around...

    Best of 2022

    These are my best astrophotography images for 2022. As to why and where is mainly decided randomly and more importantly where the target lies in the southern skies (the higher the better to minimize light pollution effects). Edit: Would like to add that I have just been notified of my second...

    Orion (M42) and the Running Man (SH2-279) Nebula in LRGB

    Orion Nebula (M42) and the Running Man Nebula (Sh2-279) in a 2-panel mosaic shot in LRGB. Was still able to showcase the interstellar gas and dust clouds surrounding M42 and Sh2-279 without blowing out the core (trapezium) too much of M42. M42 is only 1,500 light-years away and about 30 to 40...
