The Iris us usually shot as a wide-field object to capture the extended dark nebulae. But with my filter wheel out of commission on my larger camera I decided to shoot it close up with an 8300 chip at 2563mm. Small pixels aren't the best way to shoot dim stuff but I was able to take advantage of some very nice seeing with some small pixels!
