A few test shots with the new modified T3i

These are all single exposures. I’ll shoot calibration frames and do stacked images the next time I go out. I didn’t have much time for this shoot so I wanted to get a few different targets to get an idea of what this camera can do. You can really see how the reds show up. That’s what the modified sensor is supposed to capture.

My Astrophotography Equipment

Because several has asked, here is my current equipment.

Camera Bodies

I currently own a Canon 6D and a modified Canon T3i. The 6D is my main camera for most things I shoot. It is full-frame and is the most affordable full-frame DSLR that I am aware of. For astrophotography I mostly use it for wide-field shots. Here is an example with the 6D.

The T3i for shooting deep-sky objects as it has a modified sensor that makes it more sensitive to hydrogen-alpha light. Objects like the Orion Nebula really pop with this camera. It also does a really good job with daytime shots, but it is a crop-sensor camera. I primarily use this camera with some kind of tracking when I want to shoot long exposures of nebulae, galaxies, and star clusters. Here is an example taken with the T3i.

Summer is almost over. Thank goodness!!

Summertime is a weird time for astronomers. We love the objects in the sky, especially the Milky Way and wide variety of Messier objects we can find in or near it. But the downside is the weather. Lots of rain, and even when it doesn’t rain it gets very muggy and dew becomes a big problem. We only get a few dry days during the summer when viewing conditions are optimal, so we try to take advantage of those precious nights. Here are a few shots I was able to get this past summer.
