Celestron NexStar 5 SE, Instruction Manual

Page: 22 / 54

Repeat Count - Allows you to set the number of exposures per object.
Exposure Time - Allows you to set the duration of each exposure in seconds.
Long exposures – To take an exposure for more than 1 second, your camera must be set to the “Bulb” setting. Then the
camera will take the exposure for the amount of time entered into the hand control.
Snapshots- If you want to take an image for 1 second or less, your camera should in normal mode and the hand control
exposure value should be set to “1”. When this value is set to “1”, the camera will default back to “snapshot” mode
and will take an exposure for the duration of time determined by your camera.
Exposure Delay - Allows you to set a time delay between each exposure.
Sequence End - The Sequence End option lets you select whether the imaging sequence should repeat indefinitely or stop once
it reaches the last entry.

Identify Mode
will search any of the NexStar database catalogs or lists and display the name and offset distances to the nearest
matching objects. This feature can serve two purposes. First, it can be used to identify an unknown object in the field of view of
your eyepiece. Additionally,
Identify Mode can be used to find other celestial objects that are close to the objects you are
currently observing. For example, if your telescope is pointed at the brightest star in the constellation Lyra, choosing Identify and
then searching the Named Star catalog will no doubt return the star Vega as the star you are observing. However, by selecting
Identify and searching by the Named Object or Messier catalogs, the hand control will let you know that the Ring Nebula (M57)
is approximately 6° from your current position. Searching the Double Star catalog will reveal that Epsilon Lyrae is only 1° away
from Vega. To use the
Identify feature:
•
Press the Menu button and select the Identify option.
•
Use the Up/Down scroll keys to select the catalog that you would like to search.
•
Press ENTER to begin the search.
Note: Some of the databases contain thousands of objects, and can therefore take a minute or two to return the closest
object.

The NexStar has a precise goto function that can assist in finding extremely faint objects and centering objects closer to the
center of the field of view for high power viewing or astrophotography. Precise Goto automatically searches out the closest
bright star to the desired object and asks the user to carefully center it in the eyepiece. The hand control then calculates the small
difference between its goto position and its centered position. Using this offset, the telescope will then slew to the desired object
with enhanced accuracy. To use Precise Goto:
1. Press the MENU button and use the Up/Down keys to select Precise Goto .
•
Choose Database to select the object that you want to observe from any of the database catalogs listed
•
Choose RA/DEC to enter a set of celestial coordinates that you wish to slew to.
2. Once the desired object is selected, the hand control will search out and display the closest bright star to your desired
object. Press ENTER to slew to the bright alignment star.
3. Use the direction buttons to carefully center the alignment star in the eyepiece.
Press ENTER to slew to the desired object.
