Hutech
UVB filter set (essentially RGB) |
| Camera |
SBIG
ST-10XME with AO-7 guider |
| Mount |

AP-1200 |
| Exposure |
10
exposures x 3 minutes per exposure for each RGB color channel SBIG AO-7
guider was used at around 3-5 hz. correction rate |
| Processing |
All
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. |

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.

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
