AutoGuider | Meade Pictor 201-XT Gusty winds that night. About four of the brighter stars have a couple of tiny trails at about 11 0'clock that I presume is a result of the wind gusts blowing the telescope about a bit. Autoguider maintained lock like a champ throughout however. M8 is a relatively easy object. There was absolutely no light pollution at the chosen site. Was happy to see some of the dark globules within the nebula. |
Autoguider exposure time | 1 second |

Date of Photo | 2130 Hours local, 30 June 97 |
Location | Dark site within the White Mountains at the 9200 foot elevation level. |

Additional image processing | Rescanned and reprocessed on 24 July 99. Used software I wrote to bring dim details up out of the noise. It uses an inverse exponential function. Image below is what I had posted earlier. Both images are from the same original slide. I had always been disappointed that the slide had more detail than I was able to coerce out of the image processing systems. Most of what I see in the slide with a slide viewer is now visible in the image above. |
