What planets did galileo discover


Galileo's accomplishments did not include any planet discoveries but were significant nonetheless. The 6 planets known in his time had been known since antiquity. With the help of the newly invented telescope however, Galileo discovered the 4 largest moons of Jupiter. That discovery alone was quite extraordinary but it was its ramification that created more problems.

Back in the 17th century, is was essentially Church doctrine that the Earth is at the center of the universe and that everything else - everything - revolved around it. What Galileo found was not only do these moons exist, they revolve around Jupiter, not the Earth. This what ultimately got him exiled in his later life.

One other discovery Galileo had using the telescope was that Saturn had "ears" on each side. Later, as telescopes became larger and could resolve more detail, it was found that the "ears" was actually a ring around the planet.

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.

Purchased a tasco 675 luminova telescope and the front lens was missing. Where can i get one from?


I assume you mean the eyepiece. This telescope uses 1.25 inch eyepieces. Maximum magnification is 400x on a perfect seeing night.
I would start with a 20mm plossl which would give you 33x. Enough to see the moon and Jupiter/Saturn. If you get interested, then buy more eyepieces and most important a moon (neutral density) filter.
telescope focal length (675)/ eyepiece focal length = magnification
Good places for eyepieces are Ebay, Astronomics, Smart Astronomy

I have a Meade EXT90. A black dot appears in the middle of every object I view (Jupiter, Mars, etc) with the exception of the moon. Any ideas on waht that might be? Thank you.


The black dot means you are way out of focus.

In an ETX90 Mars will always be a TINY disk, except under extreme magnification.

Jupiter is also a small disk but a little bit bigger.

Next time you try for Jupiter focus on the MOONS until they are tiny points of light like little stars.

Also certain eyepieces have this as an unwanted trait. Try another eyepiece -- start with the one with the largest number written on it which will be your LOWEST magnification.

What level magnification do I use to see jupiter or saturn in a telescope?


Your 3.5 inch telescope has a maximum magnification of about 170 power.

This is under perfect sky conditions and a perfectly collimated telescope. Galileo used 30 power magnification to see Saturn's rings and the moons of Jupiter!

Put the eyepiece with the largest number written on it into the focuser do not use the 2x barlow if you have one.

Point it at Saturn. You will see the rings. However they are almost slanted directly toward Earth right now. You will only see a thin line going across the planet.

By the end of 2010 they should open up again enough to make out the "ring" shape.

You only need about 50-70 power to view Jupiter or Saturn, or Venus. Mars is smaller and about 100 power to 120 power should permit you to see the disk of the planet (but it's still very small in the eyepiece).
