Hi Russell,
I am using SGP and you only need to manually focus once - SGP takes it from there. You do not need to calibrate anything, and as it has been said before, the scope remains on the target while refocusing, and if there is any drift during focusing routine, SGP will put it back on track after focusing routine. With NB filters, it takes about 2-3 minutes to adjust focus.

might be time to upgrade from backyard eos. |
