Field Help for WhatsUp
- GMT Deviation: The
number of hours your local time deviates from GMT. This field is set automatically from
your Computer at initialization as well as when the <Now> button is
- Date: Local Date in mm/dd/yyyy format.
This is set to current local date at initialization or when the
<Now> button is pressed. The
user can change the date for planning a future session
- Session Start Time: Local time in 24:60:60 format. This is
set to the local time at initialization or when the <Now> button is
pressed. The user can change the
time for planning purposes.
Remember, if you manually set the time to past midnight (0) for
your evening’s planning, you will need to
increment the date to be accurate for the current evening.
- Session Length: How long
you want the objects listed to be within your specified parameters. The larger the value for Session Length,
the fewer objects will be listed in the results. This is because all objects listed must
be within the altitude and azimuth ranges at the beginning of the session
and at the end of the session.
Object Type Selections
- Galaxy: Controls the
display of all objects with the word “galaxy” in the Type field
- Nebula: Controls the
display of all objects with the word “nebula” (except Planetary Nebula) in
the Type field
- Planetary Nebula:
Controls the display of all objects with the word “planetary” in the Type
- Globular Cluster:
Controls the display of all objects with the word “globular” in the Type
- Open Cluster: Controls
the display of all objects with the word “open” in the Type field
- Min Brightness:
Specified minimum brightness in Magnitude units. Will only display Objects brighter than
this field (smaller numbers are brighter).
- Size: Minimum and
Maximum allowed size in arcminutes. Will only display Objects with a size
(maximum dimension) within this range.
- Min Elevation: Minimum allowable Elevation/Altitude in
Degrees. Will only display Objects
Higher in the sky than this field.
- Az Range
(Inclusive/Exclusive): This field is used to specify the area
of the sky specified in degrees of Azimuth (0/360=N, 180=S, 270=W,
90=E). The Inclusive/Exclusive
checkbox allows you to specify whether to Include
all objects in the specified range or to Exclude Objects in the specified
range. Min must be smaller than max
at all times.
This is a more complex field which deserves a few examples.
I want to only image objects in the East to avoid a Meridian
Min=0, Max=180, Inclusive/Exclusive checked (inclusive).
I want to only image objects in the South since there is a light
dome in the North:
Min=90, Max=270, Inclusive/Exclusive checked (inclusive) .
I want to only image objects in the North since there are trees
to my South:
Min=90, Max=270, Inclusive/Exclusive unchecked (exclusive) .
There is a large tree generally North
which covers a 60 degree swath from 10 to 310 az.
Min=10, Max=310, Inclusive/Exclusive unchecked (exclusive).
The Graphic in the lower-left corner gives you confirmation that
you have the correct combination of values.
