K10D, K100D flash question

I was reading the manual for the K100D and came across the flash popping up with non A lenses. While using lenses like a "T" mount or non "A" telephoto lens on the K10D or K100D will it make the flash pop up automatically? I am thinking about buying one or both for astrophotography. I will be using "T" mounts for telescope attachment.

Don't know about the K100D, but I know that on the K10D, the flash does not pop up automatically, no matter what lens is attached.

I never like automatic pop-up flash.

It's possible you may have misinterpreted a statement in the manual about the flash always firing at full when using a non-A lens (like a T-mount lens). The manual isn't saying the flash always fires; it is saying that *if* it fires at all (and you have complete control over that), *then* it will fire at ful power. Whereas with "A" and leter lenses, the flash can automatically reduce its output as necessary.
