Martin 2 Posted September 23, 2006 Share Posted September 23, 2006 If you want to stack a load of exposures with different exsposure times and different ISO settings do you do them all together or stack each group first and then stack the final images.M2 Link to comment Share on other sites More sharing options...
Jamie Posted September 23, 2006 Share Posted September 23, 2006 Stack each group then stack all the different ISO/EXPOSURES ......... Link to comment Share on other sites More sharing options...
OXO Posted September 23, 2006 Share Posted September 23, 2006 Depends what your stacking is it for Nebula's and such too avoid burning out or is it a star cluster etc etc if the later then i would stack em all in one...James Link to comment Share on other sites More sharing options...
Ant Posted September 25, 2006 Share Posted September 25, 2006 I would agree with James.If it's a object that might be subject to burning out then stack seperately. If it isn't then do them all together.E.g. M42 needs long exposures to get the outer edges, but short exposures to capture the fine detail in the core. So you'd stack the two batches one at a time. and then use some photoshop magic to combine the two!Ant Link to comment Share on other sites More sharing options...
Martin 2 Posted September 25, 2006 Author Share Posted September 25, 2006 OK, I understand what to do for each type nowThanks GuysM2 Link to comment Share on other sites More sharing options...
Ant Posted September 25, 2006 Share Posted September 25, 2006 If it's planets then it's a whole different ball game! Couple of tips though.Stack the images, then save as the highest quality you can, then create a copy of the file. Work on the copy never the original. That way if you learn something nw in the future you can revisit your old images and pull more out of them. And if you do something stupid you can start over!Wish someone had pointed out that little gem when I first started stacking stuff. The images that I've lost over the years is soul destroying.

Ambermile Posted October 10, 2006 Share Posted October 10, 2006 Stacking planets eh? Let Registax sort them in order of quality then stack the best 20 or so. Use this stacked image as the reference frame for stacking the rest.Arthur Link to comment Share on other sites More sharing options...
MartinB Posted October 10, 2006 Share Posted October 10, 2006 That's a good idea Arthur. How do you integrate it into the avi file though? Link to comment Share on other sites More sharing options...
Ambermile Posted October 10, 2006 Share Posted October 10, 2006 Well, you optimise and stack the first 20 or so, then go back to the stack section and select it there.Arthur Link to comment Share on other sites More sharing options...
Ambermile Posted October 10, 2006 Share Posted October 10, 2006 That answer was a bit cocky guys, sorry. Here it is properly Normal bit:Select AVISelect Alignment AreaAlignLimitSneaky bit:On Optimise screen, select number of frames and click Create in Reference Frame boxEnhance image when prompted, click ContinueNormal bit again:Click Optimise or Optimise and stack as normalThen carry on as you normally wouldEasy ... And in case anyone's wondering why - you need your best frame as a reference because Registax uses it as a "benchmark" to stack the rest of the frames. The better your reference then the better the resulting stacked image will be. Link to comment Share on other sites More sharing options...
MartinB Posted October 10, 2006 Share Posted October 10, 2006 That's great Arthur. Registax quality matching against the reference image always seems a bit haphazard so this must help. Link to comment Share on other sites More sharing options...
