Webb29 feb. 2024 · Very long exposure times are often used with narrowband filters. Several hours spent imaging each color is not uncommon. Typical individual exposures might be in the range of 10-20 minutes, with 5 or 6 exposures of that duration taken in each filter. Spending a whole night imaging one or two objects is typical. WebbThis means that the filter passes all frequencies, except for the range of 59–61 Hz. This would be used to filter out the mains hum from the 60 Hz power line, though its higher harmonics could still be present.
