+RonC Posted January 23, 2022 Share Posted January 23, 2022 On 2 of the 3 images I took last night, I got 2 parallel lines across just above the centre. I had changed from the Hypercam to my Canon 1100d a couple of days ago but have never seen this anomaly before. it wasn't on the middle image of M45?? I had the Tri band filter fitted at the end of the CC.. Any idea's?? (It's only part finished!) Link to comment Share on other sites More sharing options...
Bottletopburly Posted January 23, 2022 Share Posted January 23, 2022 Banding on the canon is normal ron I would have thought calibration would sort that to a degree if using darks Link to comment Share on other sites More sharing options...
+RonC Posted January 23, 2022 Author Share Posted January 23, 2022 I thought it would too David, strange that it only happened on 2 out of 3 images? I'll do another stack later and see if I can improve it! Ron Link to comment Share on other sites More sharing options...
Matthew Posted June 13, 2022 Share Posted June 13, 2022 Hi RonC As said, definately Canon banding - I had same on 600D but calibration frames sorted it along with (if you guide) dithering. All the best Matthew +RonC 1 Link to comment Share on other sites More sharing options...
