About this Image / Über dieses Bild
| CCD: | SBIG STL-11000M |
| Image Type, Orientation: | (L+Ha)-(R+Ha)GB Composite, North is at 1:30h |
| Exposure time: | L: 20 x 900 sec., Ha: 14 x 900 sec., R,G,B: 4 x 900 sec., all 1x1 bin |
| Exposure date: | May 26th/27th, 2009 |
| Location: | Skinakas Observatory at Crete, Greece, remote-controlled from Bad Arolsen amd Much/Germany |
| Filter: | SBIG 2" LRGB filter set for STL |
| Instrument: | Ganymed 60cm-Hypergraph in secondary focus (f=4940 mm) |
| Photographer: | Josef Pöpsel, Stefan Binnewies, image editing by Stefan Heutz |
| Seeing (FWHM): | 1.23" |
| Remarks: |
Image editing was difficult, since for some of the luminance images the filter weel partly obstructed the CCD. Even after 3.5 hours of Ha exposure, this data was still very noisy. Both problems were perfectly solved by Stefan Heutz, who did the image editing. |

Bemerkungen: |
Die Bildbearbeitung war schwierig, da bei einem Teil der Luminanzbelichtungen das Filterrad partiell im Gesichtsfeld der CCD-Kamera stand. Auch das Einfügen der nach 3,5 Std. Belichtung noch sehr dünnen Halpha-Daten gestaltete sich nicht einfach – beide Probleme hat Stefan Heutz im Rahmen der Bildbearbeitung souverän gelöst. |
