@whwang,

” Low priority

1. capability to handle images a few times larger than 700 MP. ”

Yes, something for the future, but definitely on the list

“2. To allow to use a wide-field low-resolution image as a registration reference. Such an image can even serve as a reference for sky gradient subtraction and image normalization.”

I understand, should be possible. Will add tot the RFC list

“3. Dark optimization. Sometimes darks are taken under slightly different temperature. It will be nice if APP can automatically scale the dark to better match that in the light frames.”

Yes, I have been thinking about this for a long time. Dark scaling is full of potential problems though, since not all signals in darks behave linearly, like we would like them to do, amp glow for instance. So while it would make life easy for the photographer, he could easily have sub-optimal calibration due to the scaling which doesn’t work perfectly. But maybe my concerns can be removed if you or someone else can refer me to good literature on this subject.  I would love to implement this as soon as possible if there actually exists a very robust way for all sorts of different sensor technologies that are being used in the amateur and pro market, which I think is very hard to find. How’s your professional experience in this regard?
