Question about Celestron NexStar 8SE Telescope
As I said before the telescope does not give any details of the image it sees. I could see very clear images of the planets and stars, but due to this problem I cannot see anything clearly. I can see better using my own eyes than thru the telescope.
I'm having the same problem with my Astromaster 114 EQ . I can see better than the scope , but it is clear when I focus on images about 35 40 away in the daylight. I am now ready to trash this thing. For I had a Meade many years ago and it was great ,but I gave it to a friend to use, but he broke it. Next time Meade.

SOURCE: 2-star alignment
I also have an 8i, but decided not to upgrade the controls yet. I've had my scope for about four years. I have experienced the same problem and am not sure what what causes it. Some nights, the scope tracks alignment all night, other times it does not. When the later occurs, the only thing that helps is to repeat the alignment picking new targets. One night, I had to repeat alignment 3-4 times. Also, I highly recommend a book by Michael Swanson, "The Nexstar User's Guide". It's an easy read, very specific and keeps the novice in mind. It should be included with every Nexstar sold. Go online to: http://www.Nexstarsite.com. Hope this helps. John

If this is a Newtonian reflector or a catadioptric scope (Schmidt Cassegrain or Maksutov) you may be trying to use it at too low of a magnification. Your magnification needs to be high enough that the exit pupil is less than 5 mm; to figure this divide the focal length of the eyepiece by the f-ratio of the optical tube. If this quotient is 5 mm or more the black spot you are seeing is the shadow of the secondary mirror.

Reset the hand controller and reload the firmware. You will need a special cable available from Celestron to load the firmware. The software is available for free on the Celestron web site.
