Radian Raptor 61 Review

|Telescopes|25 Comments

The Radian Raptor 61 is a triplet apochromatic refractor telescope for astrophotography. It features a compact design with features custom-suited for wide-field, deep-sky astrophotography. Since the Raptor arrived in September, I have taken some of my best astrophotography images to date with it. In this review, I'll share all of the image examples I have collected since the prototype arrived at my door.  This compact telescope was designed for astrophotography with a camera attached, not visual observations through an eyepiece. If you're interested in taking pictures of deep-sky ob…

The AstroBackyard Backyard of the Week highlights astrophotography setups from around the world. A "backyard" can be a balcony, driveway, garden, or wherever else you set up astrophotography equipment at home. By taking a behind-the-scenes look at the equipment amateur astrophotographers use to take deep-sky images, you can get a better understanding of the process. This week’s backyard astrophotography equipment profile comes to us from Helena Cochrane in Scotland. Location: Scotland, United Kingdom I have watched Helena progress from a DSLR and a manual Dobsonian telescope to a…

Types of Telescopes

There are many different types of telescopes available for those interested in exploring the night sky. Telescopes come in a variety of designs, some of which have been around since the 1600s.  The first type of telescope ever designed was a refractor, designed by an eyeglass maker in the Netherlands in 1608. Soon after, Galileo improved on this refracting telescope design and applied its uses to astronomy. The three main types of telescopes are refracting telescopes, reflecting telescopes, and catadioptric telescopes. There are many variations and hybrid designs for each type.…

The AstroBackyard Backyard of the Week highlights astrophotography setups from around the world. We break down each piece of the system so you can understand exactly what goes into a successful imaging kit.  This week’s backyard astrophotography equipment profile comes to us from Christopher Mills from Michigan, USA. Chris uses a Samyang 135mm F/2 (Rokinon 135mm) lens to capture his deep-sky images. This is a spectacular camera lens for astrophotography, offering the perfect mix of focal length and aperture for many deep-sky projects.  His setup is extremely portable a…

Astrophotography: The Jellyfish Nebula

|

The Jellyfish Nebula (IC 443) is a supernova remnant located in the constellation Gemini. This nebula is approximately 5000 light-years from Earth and is estimated to be roughly 70 light-years in size.  In the wide-field telescopic view below, you'll notice two bright stars, Tejat, and Propus (Tejat Prior). The locate the Jellyfish Nebula with your telescope, use these two bright stars as a guide. This image was captured from my light-polluted backyard using a dedicated astronomy camera, and a small refractor telescope. The image includes 2.6 hours of total integrated exposure t…
