M57 (Ring Nebula in Lyra) 2003-08-09, 1:25 UT Integration time: 18 minutes video 8" Newton, f/6, Prime Focus Mintron SW-Videokamera processed with Giotto 1.24 With almost 30 Celsius in my dome the mintron showed a lot of hot pixels which made the resulting image a little messy. Still I think it is worth showing it. The shown part is enlarged by 2. The image below is an image which I took with the same teslescope setup but with the ST5. It is a part of the full image, enlarged by 2 as well. integration time: 10*30 seconds |
