My camera is back!

Here’s a shot I took with it today. The RAW image is definitely very pinkish-red, but as I was told, it’s not a rough job to correct for the additional red sensitivity. I think, because the red is so hot, I’m losing a little dynamic range in the normal regime as well, but as you can see here, it’s not a severe problem. Now if the weather will give me a break, I’ll give the camera a real workout on some emission nebulae!
