How can I view the moon properly in my telescope?

Question

Hi, I am having problems viewing the moon under my reflector telescope. I use one with 90X magnification but sometimes all I see is white light.

How can I view the surface of the moon well?

Answer 1

Magnification is the least of your concerns, even though telescope manufacturers use that feature as a main selling point.

Seeing, in other words, how atmospherically stable the sky is, is just as important and not all clear skies have good seeing. When heat rises, it can cause images to wobble very slightly and that can result in not seeing anything more substantial than white light...and white light that you cannot focus on either!
You could invest in a lunar filter but I would recommend you try viewing the moon while it is in either of its crescent phases. This will:
1. cut down on the amount of light blaring back through the eyepiece
2. allow you to see any of the moon's craters much more easily as full moons tend to be overbright and will "flatten" the image in the scope
3. allow you to take advantage of the fact that magnification in general can make even the dimmest objects appear brighter

Try that for awhile and, if that doesn't work, you could consider buying a lunar filter.

Answer 2

Start out with a 26mm or higher eye piece, then once you have the moon in focus you can gradually go to 12,10,8mm, if you want to study any particular crater. If you are always having trouble finding something, start with the 26mm eye piece.Once you have the moon in focus, make sure that the same features on the moon are centered in your finder scope. And with the focusing knob, go all the way one way , and if it doesn't focus go the other way.

Answer 3

try a lower magnification. how big is your scope? maybe 90x is too much for its optics.

try focusing with a weaker eyepiece. if that doesn't work, then try focusing yours on anything in daylight, make it something fairly distant. if you still have troubles try adjusting the eyepiece in its setting. usually they're just held in by screws trying loosening them a bit and moving the eyepiece up or down a bit see if that helps any.

if none of this works then, it might be a problem with your scope.

Answer 4

90 x is not good enough get the on which cost abt 2000 dolla
