andrea tasselli: So last night after a long time i got a clear night Went for two targets the M5 and the Veil Nebula   The M5 is about 1 hour of integration and the Veil nebula is about 2 Hours of integration Both have the same set of correction frames. The only difference is the moon was closer to the M5 as compared with the Veil. Could that be the reason for the green rings in the M5 cluster Image? Other than that the scope is performing extraordinarily well. Amazed with the results. |

Hi i have the same problem here. I think is a second mirror shadow but it doesn´t fix by flats . I could try in 3 200/1000 pds scopes and it has similar resaults. Indeed the only one it has flocked. it has more significant shadow or ring pattern. The image is resault of taking flats in different scopes and then i run dbe with 10 tolerance, normalized and substraction. I changed the spider with the same resaults... This is the first light i stacked and when i found the problem  |
