How to attach a Canon DSLR to the Celestron NexStar 4SE using the T-Adapter-C90 (93635-A) and a Canon EOS T-Ring — a simple and reliable setup for beginner astrophotography.
The Celestron NexStar 4SE is one of the most popular beginner telescopes for planetary, lunar, solar, and bright nebula photography, making it an excellent first step into real astrophotography. This post shows the exact setup I used to attach my Canon EOS 40D DSLR to the NexStar 4SE using the T-Adapter-C90 (93635-A) and a Canon EOS T-ring. If you’re just beginning telescope astrophotography, this is the first and most important connection you need to learn.
How the DSLR attaches to the NexStar 4SE
The process is simple: the telescope's visual back accepts the T-Adapter-C90, and the Canon EOS T-ring attaches to the adapter. Once the T-ring is locked onto your DSLR, the entire camera becomes the “eyepiece,” letting you capture the Moon, planets, and bright star fields directly through the optical system.

This is the complete physical connection: Telescope → T-Adapter → Canon T-Ring → DSLR. No eyepiece is used during prime-focus astrophotography.
Equipment used
- Celestron NexStar 4SE Maksutov-Cassegrain telescope
- T-Adapter-C90 (Celestron 93635-A)
- T-ring for Canon EOS
- Canon EOS 40D DSLR camera
Why This Setup Works Well
This configuration enables prime focus astrophotography, where the telescope’s optics act as the camera’s lens. By attaching the Canon EOS 40D directly to the Celestron NexStar 4SE using the T-Adapter and T-Ring, you get a stable, optically efficient setup ideal for bright astronomical targets.
This setup is perfect for photographing objects such as:
- The Moon (excellent detail and sharp contrast)
- Jupiter and Saturn (rings, cloud bands, moons)
- Venus and Mars
- The Sun — ONLY with a proper solar filter
- Bright star fields and clusters
- Bright nebulae (such as the Orion Nebula)
More advanced astrophotographers can later use the NexStar 4SE for certain deep-sky projects with skill and practice, so this telescope can grow with you as you learn. But for beginners, its strongest and most exciting results come from planetary and lunar photography, where the 4SE delivers sharp, detailed images right from the start.

Time-lapse Sunset in Manuel Antonio, Costa Rica
Here is two time lapses I've made in Manuel Antonio, Costa Rica (hotel Costa Verde).
Time-lapse sunset and time-lapse sky stars - Orion Constellation (with sky clouds). Taken in January 2011.
Hope You Enjoy them :)

Total Lunar Eclipse December 21, 2010 Winter Solstice
Total Lunar Eclipse December 21, 2010
New York, NY Celestron 4SE telescope. All exposures were taken with Canon 40D. Backyard astronomy and digital astrophotography. Weather in New Your during the eclipse time was fantastic, but a little bit cold.
The eclipse of December 21 2010 Tuesday morning was the first total lunar eclipse to occur on the day of the Northern Winter Solstice - the shortest day and longest night of the year (Southern Summer Solstice) since 1638 (first time in 372 years), and only the second in the Common Era. That will not happen again until 2094.
The eclipse was the first total lunar eclipse in almost three years, since the February 2008 total lunar eclipse. It is the second of two lunar eclipses in 2010.
Partial eclipse begins 1:33am EST
Total eclipse begins 2:41am EST
Middle of eclipse 3:17am EST
Total eclipse ends 3:53am EST
Partial eclipse ends 5:01am EST

Blue Moon November 21 2010 Celestron 4se Canon 40D
This Blue Moon from November 21, 2010 was photographed in Brooklyn using a Canon 40D and Celestron NexStar 4SE telescope, showing how different white balance settings reveal natural lunar colors.

A blue moon can refer to the third full moon in a season with four full moons. The earliest recorded English usage of the term "blue moon" was in a 1528. In 2010 Blue Moon was November 21.
Equipment Used
- Canon EOS 40D DSLR
- Celestron NexStar 4SE Telescope
Color-Enhanced Blue Moon
1. Neutralize the colors (the median of the values of R, G and B is the same).
2. Create two duplicated layers.
3. First layer set as luminosity
4. Saturate the second layer.
5. Make invisible main background layer.
6. Play games with best parameters
So those colors are real, and the only difference is that they've been exaggerated a bit :)

Hyginus is a small lunar caldera located at the east end of the Sinus
Medii. Its rim is split by a long, linear rille that branches to the
northwest and to the east-southeast for a total length of 220
kilometers
Between two seas: Mare Tranquillitatis (Latin for Sea of Tranquility) and Mare Serenitatis (the "Sea of Serenity"). Apollo 15 landing at site Hadley–Apennine region.
Tycho is a relatively young crater (about 108 million years). This age suggests that the impactor may have been a member of the Baptistina family of asteroids. A larger asteroid from the same family may have been the impactor responsible for creating Chicxulub Crater on Earth 65 million years ago, and causing the extinction of the dinosaurs.
Copernicus is a lunar crater named after the astronomer Nicolaus Copernicus. The crater is located in eastern Oceanus Procellarum. It is estimated to be about 800 million years old. The circular rim has a 30 km wide. The crater rays spread as far as 800 kilometers across the surrounding mare.
