Choose an planetary camera must consider about four factors: 1. Barlow lenses are an important tool to vary the magnification range of your telescope. For planetary imaging you want to use f/20 to f/30, the latter only for nights of superb seeing. This is ideal for Hydrogen-alpha filter use such as with Daystar models. This will indeed make the planet much larger in your image, but will also intensify any atmospheric disturbance. So, there are no duplicate focal lengths when used with the eyepieces of the Q-Turret Set, and you can achieve higher magnification than with standard 2x barlow lenses if you do planetary photography with a web or video camera, and you can make better use of the camera's resolution. Steve is shooting with a Canon camera so it is the EF mount. The reply I got from someone here on that was: Regarding f/10 vs f/20 for planets, I don't see the need for the Barlow.
