What's that? Flash? Yeah, that'd work a treat! And a macro lens? Yeah, that's what you want. You know it. You know...

To be very honest mate, I have been avoiding the flash because I am scared of it....

I think it's called flash exposure compensation...

..wouldn't know where to start or when is the time to use/not use it. It's the on-camera built-in anyway which I am told can easily wreck macro stuff?
I haven't been using the flash for the Horsehead nebula even though that's pretty dark....
I have been using natural light, and setting the aperture, ISO and shutter speed until the light meter indicates 0 or maybe a stop or two under....not right?
I didn't want to pop the ISO over 800, (yay I got that right

) as I thought it would only introduce more grain or noise...
