| Object: | M45 - Pleiades | Date: | October 5th 2008 | Instrument: | SV4 Apo + TV TRF2008 FF | Camera: | QHY8 | Exposure: | 11 x 10 minutes | Filters: | IDAS LPS | Comments: | The IDAS filter left some bad colour gradients in the image. I discovered afterwards that the camera gain setting was wrong, I have lost about 1/3rd of the sensitivity! | |
