Astrophotography with a 12nm ha filter

|Camera|8 Comments

With the aid of an Astronomik 12nm Ha filter, I can capture deep-sky images more often than ever before. With both the Canon EOS clip-in version for my DSLR and the 2" CCD round mounted version for the my dedicated astronomy camera, I collect photons in every moon phase. Despite the bright 80% illuminated moon this past Saturday night, I was able to capture some incredible deep sky photos of 2 deep sky emission nebula targets from my backyard in the city. Using my 102mm refractor telescopes, I collected isolated wavelengths of light on the Wizard Nebula in the constellation Cepheus, and Bub…

William Optics Zenithstar 61 APO Review

|Telescopes|16 Comments

The William Optics Zenithstar 61 is a doublet apochromatic refractor telescope that excels in deep-sky DSLR astrophotography.  The Z61 is the most portable telescope ever made by William Optics, a company with a reputation for building beautiful astrophotography refractors. In this review, I'll tell you why I think the William Optics Zenithstar 61 is a top contender when it comes to affordable astrophotography telescopes.  I'll cover the features and specs of the scope, and share some examples of deep-sky images taken using this refractor. You can order the William Optics Z61…

Andromeda Galaxy

Photographing the Andromeda Galaxy

|Galaxies|20 Comments

With summer coming to a close, I had one last chance for some deep sky astrophotography under dark skies. Choosing an astrophotography target at a dark sky site requires some serious thought. The key is to focus on an object that will benefit from broadband color data without the need for harsh light pollution filters. After much deliberation, I decided to spend this rare occasion with my sights set on the Andromeda Galaxy. Cataloged as Messier 31, Andromeda is a massive spiral galaxy that demands attention. This month, it's well placed in the night sky for your next astrophotography projec…

Narrowband images with a color camera

Narrowband Images with a Color Camera

|Narrowband|21 Comments

Narrowband imaging with a color camera is not only possible, but I have found it to be an excellent way of adding detail and structure to my astrophotography images. If you currently own a one-shot-color camera or DSLR, I highly recommend trying some narrowband filters with it such as Ha (Hydrogen-alpha). Ideally, you'll use a monochrome astronomy camera for narrowband (and LRGB) images, yet owners of color cameras can still tap into the benefits of narrowband filters before taking the big leap to mono. An example scenario is someone with a one-shot-color cooled astronomy camera such as…

iOptron SkyGuider Pro Review

iOptron SkyGuider Pro Review

|Equipment|31 Comments

The iOptron SkyGuider Pro is a portable EQ mount that offers a reliable solution for astrophotography on the go. The SkyGuider Pro makes shooting long exposure nightscapes without star-trailing possible. On a stationary tripod mount, star trailing begins to show in exposures longer than 25 seconds. Depending on your camera's focal length, the stars could begin to trail even sooner. To combat this, amateur astrophotographers counteract the rotation of the Earth using a tracking equatorial mount. The problem is, these EQ mounts can be heavy and obtrusive, making them spend more time indoor…
