  1. Ok. I guess I'll have to wait until fall for more experimenting. Anyway this is the result with ISO 400. I would say that the grainy noise is evened out. This is the worst possible condition in nautical twilight, and you can see the moonglow from the top of the picture. I have to try high ISO to see how that works out in the final image in the fall. The curse of living above LAT 60
  2. Ok: take a look at screenshot of the RAW files. You can clearly see the noise here. Different exposures at ISO 800 30sec/60sec, with a fairly bright sky. This noise is also quite evident in the darker subs I've taken. My goal now is to get as much data as possible and even out the noise. My take on this is short exposure at ISO400 - maybe 30 - 50 sec. Whats the experts take on this? Anyway I'll try tonight, and the sky will be bright. So I I'll post my results as soon as I can
  3. Sooooooooo....maybe ISO 400 maybe? I've always used 800. But after reading Altais link I'll try 400. Hoefully the data will stick to th RAW files. I'ts getting very technical very fast. I've got a lot of reading to do. Thanks for all the good info.
  4. SNR and photon essays can be quite interesting
  5. Nice one of M82. I can see that my approach might be right then. The conditions are wery bad now, but I think I'll try one more night this season. Target M101, 30 sec exposures. I have not tried any filters yet. Maybe I'll have a shot at RGB. Just to see how much data I can pull from a bright sky.
  6. Hi and thanks. The subs are 60sec. I can usually get 60 sec with HEQ5 and good polar alingnment. Just need to get a coma corrector
  7. Hi and thanks. I think I'll try that next time I'm doing daylight shooting
  8. Hi, Just 20min of data. Still learning the ropes. 200pds, canon 1300D, DSS
  9. Well it's not getting very dark anymore up here in the north. So I figured I'd have a go at the Moon. The picture is unprocessed and the sun is still above the horizon. Equipment: 200pds, Canon 1300D, 2xBarlow.
  10. EUREKA. Turn the saturation all the way up, move the histogram to the left. Maybe a bit to red yet, done in a hurry. I'll take screenshot of my DSS settings so I don't have to bother you guys to much
  11. Yes, colour is present. I did not change any settings after this shot. I think I'm on the right track in DSS now. I found some tips in another forum.
  12. The pictures are loaded as Gray 16-bit. That must be it. How to fix this? Have I accidentaly got only black and white trough APT?
  13. You are right wise one. Can't see any brownish colour after i have stacked. I'm using DSS. I'll go trough the settings on DSS and try again. Thanks for the help.
