|Nebulae|2 Comments

The hot nights of early summer astrophotography start late and end early. The warm temperatures at night make their presence known in my DSLR images in the form of noise. My latest deep sky project involves capturing data on NGC 6888 in H-Alpha with a DSLR.  My highly portable astrophotography equipment allows me to move the entire rig around the yard based on my imaging target. This month, I have been getting a head start on summer Astro targets in Sagittarius such as the Omega Nebula. This means waiting until after midnight for my targets to rise high enough in the Southeast for a…

How a DSLR Ha Filter can Improve your Astrophotos

|H-Alpha|3 Comments

Some of the most incredible DSLR deep-sky images ever produced, likely combined regular RGB data (A typical color image) with images using a Ha filter.  A clip-in filter for your camera such as the Astronomik H-Alpha 12nm CCD filter makes it easy to start gathering Hydrogen-Alpha images with your existing DSLR. Narrowband filters are an astrophotographers best friend.   The Astronomik H-Alpha 12nm Clip Filter for Canon DSLR'S This narrowband filter lets the h-alpha light of emission nebulae pass through to the camera sensor, and blocks almost all of the other light spec…
