M27 - Dumbbell Nebula
|Telescope||Celestron C-14 - 14" at prime focus|
|Filters||Hutech UVB filter set (essentially RGB)|
|Camera||SBIG ST-10XME with AO-7 guider|
exposures x 3 minutes per exposure for each RGB color channel
SBIG AO-7 guider was used at around 3-5 hz. correction rate
images calibrated for dark current and flat field.
MaxIm DL used for color combination. AstroArt used for RL devonvolution on red and green channels. Log scaled to bring out background details.
Image scale of 0.72"/pixel.
|Other notes||From a series of first light photos using the new SBIG ST-10XME with USB interface. Got to love that fast image acquisition time|
Another version of the above data set. In this image, the blue channel was replace by an OIII filtered image and the color balance was altered somewhat. The OIII data is quite clean and higher resolution than the data used for the first shot.
|Telescope||Aries 16" RC|
|Camera||Finger Lakes Instruments Dream Machine. Pixel scale 0.77"/pixel.|
|Mount||AstroPhysics AP-1200. No guiding done|
30 Seconds per exposure. About 75 images stacked in MaxIm DL
RL deconvolution in AstroArt
|Other notes||Sky transparency was horrible! About mag 2. However, the positive was that the sky was quite still. Even at this high pixel scale, stars were quite small. This is also testament to the excellent quality of the Aries 16" RC scope.|
Another shot (taken with FLI DM). Curves adjusted to bring out faint details in nebulosity
