Hi everyone,
Since it was cloudy this morning I processed my third image of last observing weekend, IC2948 the Bat nebula. This time I used 6x640s @ 800 ISO with the Celestron 80ED @ f/6.3 and of course the modified D70, although this gets close to CCD, especially since the jpg adds a lot of noise compared to the tif version, especially in the brighter parts! Ambient temperature was 13 degrees, and the dark frames used for dark frame synthesizing work much better now. See

Thanks Terry again for providing the web space!
Cheers,
