ASTRO-PHYSICS GTO - Search for Objects by Type, Magnitude, Catalog and All Sky Vs. Current Constellation; Whats up Now Function

34
a) Use <PREV and NEXT> buttons to scroll through constellation lists. Choose a constellation that is visible.
b) Press “6=Prev” or “Next=0” to scroll through the list of stars available within the current constellation.
3. Choose a double star. When you select an object, the screen will display the approximate separation of the stars,
constellation and object type. Remember that apparent separation may vary from year to year. Consult an ephemeris
for the most accurate data.
4. Press GoTo to initiate slewing, NEXT> to sync, <PREV to view R.A. and Dec. coordinates or MENU to exit.
Search for Objects by Type, Magnitude, Catalog and All Sky vs. Current Constellation
Use this routine to specify search parameters, e.g. if you want to view all the open clusters in the Messier catalog up to
9th magnitude that are visible in the entire sky. This is particularly useful to tailor the list to your aperture or observing
preferences, or just for fun.
1. From Objects menu, select “8=More”. This will bring you to the More Objects Menu.
2. Select Search Function. The screen shown will appear.
3. Use the Keypad to make selections to narrow the range of your search.
a) Range – Press “1” to alternate between these choices: “All Sky” and “Cur.
Con.” (current constellation).
b) Type – Press “2” to alternate between these choices: “All”, “Galaxy”, “Open Clus” (open cluster), “Glob Clus” (globu-– Press “2” to alternate between these choices: “All”, “Galaxy”, “Open Clus” (open cluster), “Glob Clus” (globu- Press “2” to alternate between these choices: “All”, “Galaxy”, “Open Clus” (open cluster), “Glob Clus” (globu-
lar cluster), “Planetary” (planetary nebula), “Nebula”, “Dbl. Star” (double star)
c) Mag (magnitude) – Press “3” to scroll between magnitude levels of 1–20. This will identify the highest magnitude
that will be included. Use this to limit your search range to objects that are easily viewed in your telescope.
The search looks at the whole number of the magnitude so if you specify a limit of 10 in your search, objects be-
tween 10–11 will appear also (e.g. 10.6).
If an object does not have magnitude data available, it is stored as “0”. As a result, these objects will appear in your
search even if they actually exceed your limit.
d) DB (database or catalog) – Press “4” to alternate between these choices: “Mess” (Messier), “NGC” and “IC”.
e) Press GoTo. The screen will display “Searching”.
i) The display will show the rst item of the search and give you several choices as shown.
ii) If there are no objects that meet this criterion, the Search Menu screen will reappear. Specify new search crite-
rion.
iii) The search times may be 30 seconds or longer if you are searching a large database, like NGC objects.
f) Press GoTo again if you want to slew to this object. The mount will slew and object data will display. Press
NEXT> for the sync menu or <PREV to show R.A. and Dec. coordinates.
g) Press Menu. The next search object will display or if there aren’t any more, the search menu selection screen will
reappear.
h) Press MENU again to return to Objects menu.
What’s Up Now Function
1. Go to the “What’s Up Now” screen. (Main Menu → “1=Objects” menu → “6=More” → “4=What’s Up Now”)
2. Press the Next>. The Keypad will search its M, NGC, and IC databases and
randomly suggest an object that is above the horizon at your location. Due to the
complex calculations that are made to select an object, you may notice a slight
pause with a message **what’s up** after pressing the NEXT> button. This is
normal. The selection is random but based on what is above your current sky ho-
