The Stunning Double Cluster in Perseus

|Star Clusters|3 Comments

The Double Cluster in Perseus The Double Cluster in Perseus (NGC 869 and NGC 884) are two open clusters in the constellation Perseus. Also named Caldwell 14 or simply "The Double Cluster", both star clusters are very similar to each other in size, magnitude, and age. This pair of open clusters lie about 7,000 light-years away from Earth. They are an easy binocular target, and an impressive sight through a small telescope. The magnitude 3.7-3.8 star clusters are bright enough to be spotted with the naked eye under the right conditions. Each of the clusters contains more than 300 blue/whi…

DSLR camera for astrophotography

Results Using a $200 DSLR for Astrophotography

|Camera|4 Comments

In a recent video, I shared my results using a $200 DSLR for astrophotography. In a hobby known for being very expensive, I think it is very interesting that such results can be obtained using an old, inexpensive camera. In this post, I'll prove to you that incredible astrophotography results are possible with an old, used, entry-level DSLR camera. And no, it doesn't need to be modified to achieve impressive results. (I've got plenty of unmodified DSLR astrophotos to prove it). You can pick up a used Canon EOS Rebel T3i (600D) DSLR for under $200 on eBay, and it will likely include a kit…

The Canon EOS Ra camera is Canon's first full-frame mirrorless camera dedicated to astrophotography. It is suitable for deep-sky imaging with a telescope, and night sky photography with a camera lens. Based off of the extremely popular EOS R, the EOS Ra boasts unique features such as 30x magnification (viewfinder and Live View) for precise focusing, and roughly 4x more transmission sensitivity to the hydrogen-alpha (Hα) wavelength. Name: Canon EOS Ra Based on: Canon EOS R Release Date: November 2019 Type: Mirrorless System Resolution: 30.3 MP Sensor size: Full-Frame…

Rokinon 135mm F/2 lens review

The Rokinon 135mm F/2 was Built for Astrophotography

|Camera Lenses|15 Comments

In this post, I'll explain why I think the Rokinon 135mm F/2 is the perfect addition to an arsenal of astrophotography lenses.  Deep sky astrophotography is often associated with a camera and telescope, but the truth is there are a lot of great camera lenses for astrophotography out there. In the past, I've covered a number of different lenses, from the Rokinon 14mm F/2.8 to the Canon EF 300mm F/4L. As you know, camera lenses come in varying focal lengths, apertures, and optical quality. Astrophotography is one of the ultimate tests of lens quality, as long exposure photography of d…

Canon EF 300mm F/4L

Using A Canon 300mm Lens for Astrophotography

|Nebulae|11 Comments

If you watched my video about Comet 46P Wirtanen, you may have noticed that my imaging gear included a Canon EF 300mm F/4L USM Lens. This may have seemed a little odd to those that are used to seeing me use a telescope for astrophotography, but a camera lens like this can be a great way to capture deep sky images. Over the years, a lot of people have asked me why they should invest in a new telescope when they already own a high-quality telephoto camera lens with a comparable focal length. After all, a prime lens like the Canon EF 300mm F/4L isn't cheap, and its got some seriously impressiv…
