Dont you have some darks from previously i.e. same CCD set point and same exposure...if so...recycle baby!

the filters don't matter with darks,  It's all down to the exposure lengh and what temp the CCD is set to at the time,  Some build a library so will have   (Example)   a set  @

5mins @ -10,15,20 degrees
10mins @ -10,15,20
15 mins @ -10,15,20

One a library is built only every now and then will you have to re do them.

high chris im doing ten minute subs

But your taking 10 mins subs,  the darks have to match the lights with exposure time & temp.
