Here is some more work from my 135mm telephoto lens. This is a 35mm camera lens mounted on my Artemis 285 camera with an Astrodon 6nm Ha filter in the chain. The lens is focused with a belt and stepper motor arrangement.
There are many interesting Sharpless Ha regions, and this one near IC1396 fills the frame nicely.
I had planned for a much longer exposure on this object, but the weather has other ideas.
Captured in ArtemisCapture, calibrated in ImagetoolsCa, combined in maxim, thuggery in photoshop. Total integration time 2 hours
