![]() An hour of M8 with Veronica, G11, motor focuser. I could use some more detail of the outlying areas (there are some nice dust globs out there), but when I tried to go after them, the background brightened up too much. Another hour or two might bring them out. I tried 2 minute exposures, but this nearly blew out the red channel. I haven't tried using the channels from different exposures separately, but that might be a good way to grab some more detail; use a 2 minute exposure for BG and a 1 minute for R. |
![]() M8, The Lagooon Nebula, Emission Nebula in Sagittarius This is from the first night after I performed the "filterectomy" on the Nikon D70. This is a stack of 12 30 second images shot from my light-polluted Newark backyard ("total imaging time" is 6 minutes). Compare to the stack of 2 5 minute images shot from (extremely) dark sky up at Shingletown. Wow, wow, wow. This is an RRGB image (I used the Red channel for both color and luminance data). |
![]() M8, The Lagooon Nebula, Emission Nebula in Sagittarius This is the same shot as the one to the left, except it's just showing the contents of the Red channel. This is wideband shot, not shot through a Hydrogen-alpha filter. Oh, Sagittarius is *really* low from my yard, too. Had to catch M8 in between The Palm Tree and the roof of the observatory. |
