The Canon Rebel T1i DSLR camera just arrived and I've been checking it out. The camera is capable of 12,800 ASA and even boasts double the pixel density from my Rebel XT! It now takes only 20 minutes to collect the same amount of unguided exposure it would normally take me 3 hours to collect, still using 15 second frames. Clearly, noise processing is different but my initial results seem very pleasing.
So, here is the Lagoon Nebula taken with the new Ritchey-Chretien telescope and camera.
Oh yeah, no amp glow either!! That's a relief.
