Astrophotography is a genre with a lot of specialized equipment designed for very specific purposes, but a lot of photographers still use normal consumer cameras to create their images. What sort of images can you create with a camera specialized for the task? Check out this great video to see what is possible.
Coming to you from Astro Backyard, this fantastic video takes a look at the Canon EOS Ra astrophotography camera. The EOS Ra was the first astrophotography-specific camera from the company in seven years (with the 60Da and 20Da coming before it), and even more importantly, it is their first ever with a full frame sensor. Canon added an optical infrared cut filter in front of the sensor that improves the transmission of light at the Hydrogren-alpha wavelength (656.28 nm) by four times, vastly improving its astrophotography performance. Furthermore, it has the capability to magnify at up to 30x using both the EVF and the rear LCD, making the sometimes tricky task of focusing on stars much easier. And of course, being an R mount camera, it can take advantage of the spectacular RF lens lineup, making it a very intriguing option for lots of astrophotographers. Check out the video above for the full rundown.
"What Kind of Images Can You Make With a Specialized Full Frame Astrophotography Camera?"
Astrophotography images, I suppose would be a good answer.
Astro DSLRs are not worth the investment. That money would be much better spent on "real" astro cameras and associated peripherals that will yield much better results.
Modifying older cameras for astro is economically sound however.
I have to agree. Find a nice used 6D and send it to any number of modifiers and you'll have a nice astro-camera. And if done properly, they can still be used for terrestrial photos. All you have to do is set up a custom white balance.
Here's a guy I know that does some of the best work with a DSLR I've seen:
