overexposed on the screen during capture or after stackinging in registax.?
make sure histostretch is not turned on during stacking.
don't go for nice looking whilst capturing. you can have the image as grainy as hell during capture and that grain will disappear upon stacking.
here is dennis avi from that fantastic night on 4th feb. this is the first step of registax, image is very grainy and bright, but all of this can be taken out after.
in reference to this first one, where do people's capture preview screen relate? brighter, dimmer???
2nd image is the create reference on 50 of 480 frames, no wavelets. as you can see the noise has gone. no histostrech, just simple optimise / stacking.
3rd on is a finished stack of all 480 frames
4th is a finished product with rbg align and soft wavelets.
ps, dennis's data is like working with silk or viewing thru a 200mm takahashi refractor. (don't worry stu isn't imaging yet, so won't look at this thread and spam this tread with drool. no doubt he will sense that something was said in a thread, but will tear his hair out looking for it!!!)
