Question 1

can this see half of the moon at night

Accepted Answer

The 50x magnification eyepiece will show all of the Moon at one time. The 125x magnification will show the Moon much larger, it will look like you're right next to it in space.

Question 2

which eyepiece is use to see the planets clearly and big

Accepted Answer

-The best all-around combo I've found is with a 20 mm Plossl eyepiece (my own purchase, although the 25mm included will work very well with a slight drop in magnification) + a 5x Barlow lens. However, if conditions are good, you can go to the 10 mm with the Barlow & this will result in Jupiter (currently near opposition (2018/05/05) occupying much of the field of view.

-Bear in mind that this is with my using the Orion EQ-1 equatorial mount as well- trying to keep something in the field of view with this amount of magnification & a tabletop mount would give you fits. Having said that, however, I would definitely pick up a decent 5x Barlow- it will enhance the performance greatly for only a relatively few $$$.

-I have this scope myself & with the EQ mount, a range of eyepieces plus Barlows & filters? You'll have some great views of the planets.

Question 3

What eyepiece would give this telescope 180x magnification?

Accepted Answer

Ryan, thank you for contacting Orion Telescopes and Binoculars.  In order to get to 180x magnification, you would need a 6.9mm eyepiece.  I hope this has been helpful.

Question 4

Hello! Would you mind to write the  size of this telescope's box and weight of the box?

Accepted Answer

Not sure what your purpose is in seeking the box dimensions, but if it is to use as storage and safe transport of the scope, I have a suggestion. Save the packing and grab a cheap carry-on sized suitcase. Pack the packing in the suitcase so it doesn’t slide around and you have a good container. I’ve done this with a Celestron NexStar 8” SCT though it required a full sized expandable suitcase. Dark Skies and Pleasant Thoughts!
