/* Sky flat recipe for STE3/4: Modules */
Since all exposures with the STE3/4 must be performed via a module (except for snapshots), it may seem challenging to set up and edit modules quickly enough to obtain sufficient sky flats during twilight. However, you can do this pretty quickly using the following example:
# '''Before twilight''', set up a module for your first filter and an exposure time of 1s (do not go below 1~s1s), with 1 repeat.# For evening twilight, perform [[#Start-up recipe|steps 1-10 11 of the start-up recipe]] to setup the telescope and facility prior to sunset.
# Click the small grey "On" button below the SAAO CCD image display.
# Shortly before (morning) or after (evening) sunrise/set ~10 minutes after sunset for B) click "Snapshot" → Exposure time = 1s. Click "Ready" to expose.
