Another revisit of an old target, with better gear and better conditions. This is the Pelican Nebula in the constellation Cygnus. Shot in narrowband over one night, and presented in the “Hubble palette”. Two takes – one wider field, and one close-up with the stars removed. In both cases the image is rotated and mirrored…

Imaging deep sky objects from a suburban driveway forces one to find ways to deal with light pollution. Light pollution is the enemy of astronomers – but in reality, there are ways around it. Some of the most beautiful objects in the cosmos are called emission nebula. They are clouds of gas, often where new…

Yeah, it’s been a couple of months since we’ve done a live star party online, or posted any new pictures. That’s just summertime in Central Florida for you – it’s been too cloudy to do any imaging or observing. The skies should start clearing up more in a couple of months, and we have every…

This is the Christmas Tree Cluster (turn the picture upside down and you might see it!) But the real focus here is the Cone Nebula at the bottom of the image, and the Fox Fur Nebula in the upper-right. Lots of red Hydrogen gas here being ionized by the young stars it formed. Also visible…

The Monkey Head Nebula is located about 6400 light-years away, in the constellation Orion. It’s a gorgeous cloud of gas surrounding a cluster of young stars. I processed this data a couple of different ways; one using the “Hubble palette” and another using my own color scheme. The colors represent different kinds of ionized gases:…

Located about 1,300 light-years away, the Iris Nebula is a reflection nebula – unlike most of the nebulas on this site, it’s not made of ionized gases emitting light of their own. It’s just starlight reflecting off clouds of dust. Reflection nebula are harder to image in light-polluted skies, since the narrowband filters we use…
