Question about Bushnell NorthStar Goto 100mm 788840 Maksutov-Cassegrain Compact Telescopes

1 Answer

Computer not accurate

Last night when i was looking through my telescope it didn't "go to" the correct planet star or galaxy. When the moon was clearly out in the sky,and when i told it to go to the moon it said that the moon was below the horizon at this time. Why is it so unaccurate when i alighned earth correctly? Is there a way i cud correct this or reset it?

Looking through the manual (link follows) please check that you set the time in 24 hour clock with timezone correctly. Also the date & of course location. I see no reset function in the manual but I guess leaving the batteries out for a while will reset it. Manual link: http://www.bushnell.com/customer_service/manuals/telescopes/78-8876_1LIM.pdf Also although it says you do not need to know where the stars are you're aligning to it's good to have some idea that you're actually aligning with "Mizar" or whatever. You can find maps of the night sky where you are on this link: http://www.wunderground.com/sky/index.asp Finally check if there is a local astronomy group that you can join, they are always ready to encourage & help people.

Cannot see anything thru telescope even daytime


  1. Get Stellarium or another fine astronomy program
  2. During the day, point the telescope at a part of the landscape about 100 yards away.
  3. Use the lowest power eyepiece (highest number) in the focal tube.
  4. Center the landscape object in the telescope.
  5. Align the finder scope so that it points exactly where the main telescope is.
  6. At night, leave the scope out to reach thermal equilibrium (about an hour for small reflectors and refractors)
  7. If the scope is on a EQ mount, polar align.
  8. Point the finder at the moon. The moon should be in the main scope also.
  9. Practice finding the moon before you start on the planets
  10. Once you are comfortable with the moon and planets, you can go for the deep sky objects

Seeing the stars


The stars will always be "points in the sky" no matter what telescope.
The stars should be sharp, focused points in the center of view (more blurry towards the edges because of the stock eyepieces and the fast telescope mirror) if not, the telescope may need collimation. (look at instructions and/or search online. Plenty of instructions on the net.)

Hi, a few days back I purchased Nexstar 4SE. I set it up exactly how it says in the manual still I cannot see any magnifying views from the eye piece. While aligning the telescope I can find the moon from...


Stars will always appear as points. It is not possible to magnify them enough to see them as disks because they are all extremely far away. A telescope will however show you stars and other objects that are too dim to see with the naked eye.

You will be able to see the planets as disks, and even features on the planets, such as the bands on Jupiter, the rings of Saturn and the phases of Venus, and also moons around some planets. There are other objects that will show more detail when magnified, such as nebula. You will be able to see a lot of craters and other detail on the Moon.

Your problem is simply that you are not pointing the telescope at these objects. This seems to be one of those telescopes that "automatically" finds objects, but these so called "go to" scopes only do this when they are set up properly. I can't say what step(s) you have missed, but clearly even if the scope thinks it is pointed at the moon, if you can't see the moon, it is NOT pointed there. The Moon will fill the field of view even with the least powerful eyepiece. If you are seeing stars as points, then the eyepiece is focussed and working properly.

Hiii, would like to buy a second hand telescope from a guy, but i dont know if this telescope is good or not for a beginner. I would like to see the moon up close, and i would like to see some...


I believe that scope is on a EQ mount which you must polar align in order to use the telescope. It is also a small refractor. You will be able to see the major planets, a few star cluster, and a few bright nebula, along with double stars.

However it is only about 70mm so it's light gathering power is low. Look at this type of telescope.

Hi, I have assembled my telescope, i can see through it in the day..but at night even though it is a full moon, it gets difficult to get a clear picture. The manual says you can see lots of stuff with it,...


You have a 3-4 inch reflector. DO NOT USE the 2x barlow. It creates too much magnification for that small telescope.

Put the eyepiece with the largest number written on it into the telescope and then try again.

Objects in the sky are very tiny. The scope must be pointed directly at them to see them.

Starguide can not even find the moon let alone planets


question answered on another post-- the moon and planets are CALCULATED and will always have some error. Your initial alignment MUST BE very accurate.

How to use telescope at night?


Many people have the same problem-- with these small telescopes you are stuck with seeing only the moon, and several other planets, and maybe a few bright star clusters.

These are all TINY objects (except for the moon).... when you look through the telescope you are looking at a section of sky about the size of your fingertip held at arms length-- the scope must be pointed DIRECTLY at the object. Practice on the moon first-- and then try to find Saturn which is up in the sky right now-- it looks like a dim (slightly yellow) star.
