Firstly, your scope is a Newtonian, so there may be difficulties reaching focus for near objects.

Secondly, moon is a "moving " object, so you have to use a land object to align. Same for stars and planets, they are "moving" objects.
sry, don't quite get u abt aligning using land objects. because the manual states that the starpointer is to be aligned using stars or planets

let me quote it to u

To align the Star Pointer finderscope:
1. Before using the StarPointer, you must first remove the protective plastic cover between the battery and the battery clip.
2. To turn on the Star Pointer, slide the On/Off switch to the 1 "On" position. To increase the brightness level of the red dot,
slide the switch to the 2 "On" position.
3. Locate a bright star or the Moon and center it in a low power eyepiece in the main telescope.
4. With both eyes open, look through the glass window at the alignment star.
5. If the Star Pointer is perfectly aligned, you will see the red LED dot overlap the alignment star. If the Star Pointer is not
aligned, take notice of where the red dot is relative to the bright star.
6. Without moving the main telescope, turn the Star Pointer's azimuth and altitude adjustment knobs until the red dot is
directly over the alignment star.
The Star Pointer is now ready to be used. Remember to always turn the power off after you have

I can't believe Celestron wrote such rubbish in the manual. Let me give you the steps:

1) Press the directional buttons until your scope's centre of view is at a pointed far away object. Those red light on top of buildings is fine, but it must be far away.

2) Switch off the SLT

3) Now adjust the starpointer until the dot is superimposed on the same object.

4) Now you may carry out the GOTO alignment process for your scope.

Anyway, Meng Lee is right - it is definitely more advisable to align your starpointer at a land object that is not moving.

1. Point your telescope at the land object (make sure it is a distance away and your scope is able to focus on it) and centre it. You might want to use a higher magnification to better centre the object (smaller field of view).

2. Align your finder to it.

3. Try finding the moon again.

Also need to ask another question - is your scope able to focus on any objects (whether land or astro) so far? Try pointing at a far land object and focus. If it really really doesnt focus you might need to do some collimation - but dun let that worry you yet. :)

Edit: I see Meng Lee posted at the same time .. :)

thanks guys for the advise, i will try again tomorrow. i think i can focus on the object. i manage to catch a very nice glimpse of a partial moon for 0.1 seconds before i lost it. =)
