Estimated Total Execution Time (hours, including overheads)

3:59:40
```

General Description

This run consists of imaging several PNe (a short exposure and several
 long, jittered, exposures each). Due to the extended nature of each target, we need
 the nebulae to be positioned in the centre of the Master chip. Thus, we have slightly
 modified target coordinates so as to achieve it (even after applying rotation offsets).
 Please keep in mind that the Finding Chart provided is centered on the PNe (and
 not on the Telescope preset target coordinates).

Waiver Requests

An additional target, namely Hen 2-186 (16 59 36.064 -51 42 06.46 J2000.0),
 and the use of filter OIII#589 for imaging the target M2-9 (in addition to the originally
 requested NII#653) were requested on January 24th. Both were approved on January
 25th.

Critical Observing Condition Constraints

```
A seeing <= 1.0" is required.
```

Time-Critical Aspects

Each target observing window is described in the Time Interval section
 inside its OB.

Special Execution Requirements

---(Empty)---

Special Calibration Information

Several twilight flats in the [NII]#653 filter are required for every
 OB. Additionally, we need twilight flats in [OIII]#589 when running the OB named
 M2-9.
