Jupiter’s Great Red Spot May Soon Disappear…
Or maybe not…either way – Jupiter imaging season is upon us. Jupiter’s Great Red Spot May Soon Disappear… Scientists aren’t quite sure what will happen to the shrinking mega-storm. Aside from its size, the planet Jupiter is perhaps best known for the roiling vermilion tempest that swirls south of its equator. The storm, which is big enough…

The benefits of adding more subs to your stack
A good guide about the advantages of image stacking for DSLR astrophotography The benefits of adding more subs to your stack Adding multiple exposures to create a single image is one of the key elements of doing astrophotography. It enables us to get rid of bad pixels, satellite trails, noise while increasing signal to…
