as soon as you said 'histogram' your exposure determination was clear. I know that the Ha filter is a narrow bandwidth and it tends to lengthen exposures greatly, I was curious how you determined the 'correct' exposure, just forgot about histograms, I tend to image by instinct and what looks correct and interesting. we'll be doing deep CCD work from the HAA site in a few weeks, we're in the process of installing the isolation floor for the dome. As it is now, the pier and dome are tied all into the same 10 ton block and when we have a breeze, the dome shakes the pier slightly but that's not acceptable so a tube steel frame is being fabricated that will carry the dome but be connected at all to the pier block. When that's pau, we image!!
Aloha and thanks Rob
