Re: [APML] Pentax 67 300mm, GM-8, and more questions....

The color quickcams were a lot less sensitive than the B&W versions.
That being said the integration time on my B&W through an f/8 500mm fl
mirror lens is still up around 1.2 seconds with Deneb as a target. With
a 90mm f/5 Roland should have faster results.
