Yes the lower the ep number the more powerfull. Divide the focal lenght of the OTA by the ep focal length to get the magnification. But as I said a rule of thumb for max power is roughly 2x the objective diameter of the OTA. The SE4 is roughly 100mm so 2x100=200 the max working power. BUT it also depends on seeing. If the atmosphere is warm and there are lots of thermals then the image will wobble, increase the power and you get more wobbles and often blurring. The 9mm should give decent views of Jupiter. But in general terms work from low power upwards, you can then judge the deterioration, if any, as you increase the power. Using the barlow helps, but it can mean a less brighter image (and less contrast) as there is effectively more glass between the object being viewed and your eye. -
