Support for ASICAP FITS header: EXPOINUS

In ASICAP (I'm using version 1.2 on Mac) the exposure time is identified by "EXPOINUS", in microseconds. APP 1.075 doesn't recognise this and reports zero exposure time. My stacks still turn out OK, but it would be nice to also recognise the somewhat odd naming of the exposure time. Can this be added in future versions?

@ralph There are documents describing the FITS standard. Wouldn't it be better to contact ZWO and ask them to make sure that ASICAP adheres to those standards? I am aware that this doesn't solve the issue with your images and perhaps a small (python?) script that rewrites the FITS keywords into what they are supposed to be could help. I can give you a hand there if you are not familiar with python.

I just saw this post on the ZWO forum:

Out of curiosity, did you open that topic @ralph or is this someone else?

That is indeed a weird way to name it, indeed it would be a good idea to also ask ASI about it, they might change it maybe. If not, I guess Mabula could add it, but if it's totally non-standard and only with that program, he might not.
