Jan 2008 (IC2118)

This was taken on the night of January 7th from Chiefland Astronomy Village in Chiefland, Florida. Imaging at 29 degrees of latitude N was a real help on this image.

RGB 70-70-120m using 10m subs. TV-76 with 0.8x reducer, SBIG ST-2000 with CFW-8 and Astrodon filters, EM-200 mount. 5 sec guide exposures using the ST-2000 guide chip. Calibrated, aligned and sigma reject combined in Maxim. RGB channels merged and processed in PSCS.

Taken 02.February 2008 from my "Garden-Observatory" in Germany.
Optics have been a Intes Maksutov MK-67 150/1800mm @ f/12
Camera was my SBIG ST-2000XM and CFW-9 with Astronomik-Filters.
The diffraction spikes are caused by my focusing aid, which
i glued in front of my telescope...

L:R:G:B with 255:40:40:40min
15 minute Subframes for Luminance bin 1x1
5 minute Subframes for RGB bin 2x2 (a little to short exposures to get real good colours....)
All frames selfguiding with cameras built in chip.

Image reduction in CCDSoft
Subframe combining in CCDStack
RGB combining in CCDStack
LRGB combining and final adjustments in Photoshop CS2
