Inconsistent pointing I can align my 9.25 advanced scope with saturn then I ask it to go to mars and it points down at my deck. What's up?

Something similar happened to me when I had done a quick align. I asked the scope to go to the moon, which was obviously visible above the horizon but it pointed downwards. I found out that I had entered the date (month day year) in the wrong order (day month year - as is common in Sweden). Just a long shot...

Cannot see anything through my tlelescope


  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

Cant get an image.Is it right that the view finderimage is upside down


The image of all astronomical telescopes are upside down (SCTs are upside down and reversed). RACI (right angled, correct image) finders do produce a right-side up image. For daytime use a erect image prism eyepiece.
Follow below instructions (except 7 in your case)

  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.

Science tech 262 manual


Can't find a manual. This is a 76mm reflector on a Alt/AZ mount.
1. During the day, put in the 20mm eyepiece and point to a object around 100 yards away.
2. Focus on the object
3. Align the finder to the object in the eyepiece
4, Set up at night, give the scope time to reach outside temperature
5. Point scope with finder at the moon. (More than half full will be too bright)
6 Use the lowest power eyepiece (highest number) and focus on the moon.
7. You may now use higher power eyepieces to observe.
8. Pointing the scope usually involves loosing 2 knobs to move the scope in up/down and side to side motion. There may be slow motion controls to adjust the scope as objects in the sky move.

Cant see anything through the view finder


1. During the day, use the 17mm eyepiece on a object outside (telephone pole, water tower, etc) then align the finder to what you see in the scope.
2. Put in the 7.5mm eyepiece and fine align the red dot finder.
3. At night, point the finder at the moon (less than half moon or the image is too bright without a moon filter) Use the 17mm eyepiece.
4. Once you see the moon, switch to the 7.5mm lens and enjoy.
5. Download Stellarium or any free astronomy software and see what is in your sky tonight. Your scope should be able to see Jupiter and its moons easily.(Saturn, Mars and Venus when the time is right) Open clusters like Pleiades will be nice is this fast scope.
5. If stars are not sharp, you may need to collimate the scope. Look online for general instructions.

Aligning my scope and slewing problems


You need to synchronize the telescope with stellarium. Center the telescope on a known star, then select the same star on the laptiop and 'synch' with it.

Nothing------ stars are always JUST STARS no matter what scope you are using. They are too far away to see a disk. Point this scope at Jupiter, Saturn, Venus, Mars-- or other star clusters and the moon.

Remember stars are always just points of light-------- using Google look up the "Messier Objects"--- there are 110 of them in the night sky at different times of the year.
