August 2003 Observing Run

All images were recorded using ST10 MXE CCD camera, SBIG CFW-8 Filter wheel, autoguiding enabled. T600mm telescope, focal length = 2245 mm, Wynne field corrector, binning 1x1, scale is 0.63arcsec per 6.8µm pixel, digital robofocus has been used. PRiSM software was used for acquiring images and processing,. Click over images to get the full resolution image (beware : large file !).

Have also a look to the TNO (trans-neptunain asteroids page )

Most of the exposures are made of basic 240sec exposures....

M27
Exposure R=480s V=720s B=960s

The same image below has been re-worked : DDP + unsharp masking

Bubble nebula, 2.8" arcsec seeing, B images were recorded thru cloudy sky
B Filter 6 x 240s Exposures
R Filter 3 x 240s Exposures
V Filter 4 x 240s Exposures

M15 - 180s exposure, 3.5" seeing

NGC6888 Halpha filter (Astronomik) - 1440s exposure time, 3" seeing

N660 720s exposure time
Seeing : ~2.8"

Full N660 image, a close look to the background shows very tiny and deep galaxies....

This picture shows (here) how the PRiSM software was used (lots of telescope control panels !) :
- CCD camera acquisition control panel
- Autoguiding control
- Dome control
- Digital Focuser
- Telescope drives and encoders
