Light Pollution Filters for Astrophotography

|Equipment|21 Comments

One of the most common questions I receive each day is which light pollution filter I recommend for astrophotography in the city. There have never been so many choices available, with each one offering their own advantages and disadvantages. Couple that with the fact that these astrophotography filters can be expensive, and you've got some tough decisions to make. Over the years, I have had the opportunity to use a number of filters designed to improve astrophotography performance. This includes both deep-sky camera and telescope configurations, and with wide-angle camera lenses. In the fol…

iOptron CEM60 Equatorial Mount | First Look

|Equipment|13 Comments

The iOptron CEM60 is a center-balanced equatorial telescope mount that provides an excellent platform for astrophotography. This astrophotography mount has created quite a buzz both in terms of design and performance.  With the mount itself weighing in at just 27 lbs, this mount can handle a substantial payload deep sky imaging gear of up to 60 lbs. This opens the doors to countless astrophotography telescope configurations. I've been given an opportunity to review the iOptron CEM60 this month, and hope to share my experiences in astrophotography along the way. This a step up from the…

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|14 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.

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…
