Plenty of Wide Targets

14. 2. Resolving Power

15. Allows you to separate double stars.
Scope will split stars further apart
than 1arcsecond
Moon is 0.5 degrees, 30 arcminutes 1800 arcseconds

16. 3. Light Gathering Power

17. Light Gathering Power

18. Same Magnification

49. Do
1. Do explore the sky.
2. Do let the scope cool outside
for 30-45 minutes before use.
3. Do let your eyes dark adapt
for 20 minutes.
4. Do clean the eyepiece lens
only if necessary.
5. Do brush the dust off
eyepiece before cleaning.
6. Do turn off the EZ Finder.
7. Do cap the telescope and the
eyepiece when finished.
Don’t Do
1. Do Not spray bug spray near
the scope.
2. Do Not bring in the scope
when you are taking a break
or it might fog over.
3. Do Not touch the lenses or
mirrors.
4. Do Not clean the mirrors.
5. Do Not try to adjust the

What to Do and What Not to Do!

50. Tips
 Practice in the daytime but note objects will be
upside down.
 Dark adapt for 15-20 minutes.
 Twinkling stars mean unsteady skies.
 Observe objects that are high in the sky for best
results.
 Set the red dot finder on the dimmest setting you
can still see and turn off when done.

51.  Dress for the cold.
 Too cold? Observe bright objects from
inside.
 If inside, turn off all lights.
 Push Telescope to keep aligned
 Star with Lowest Power then Zoom in
 Wrap hand warmer around eyepiece if it is
fogging.
 Want to take pictures of the Moon? Hold a
camera in front of the eyepiece.

52.  Try your hand at sketching what you see at
the eyepiece.
 Carry by holding onto the hand grip and
cradle it in your arms.
 Strap the scope in with a shoulder harness
and seatbelt.
 Come to a star party if you want to see
more.
 Look up people for whom the telescopes
were named.
 NEVER LOOK AT THE SUN!
