That's a lot to do just see features. It just like color filters for a microscope.

So it may seem. But it's not truly required for anyone to use a filter - EXCEPT  FOR LOOKING AT OUR SUN! - You're quite welcome to throw all ideas of filters out the proverbial window. Most of us do and view things as they are without additives or preservatives. But I've found that filters can offer a different view of your chosen object - one object effectively become two different objects - as a view with no filter, and without the filter.

To each their own!

I think your need welder's glass.

No, you don't. You need a proper Sun filter.

Welder's glass is not suitable for viewing the Sun. Don't try it!

You mean some thing block out center of the sun? But doesn't damage the telescope?

Some like see the sun, I prefer to see the moon and stars and planets

Do not use welder's glass as a solar filter. There are filters, made from either glass or polymer film, specifically designed for solar viewing. Don't risk it, use the correct equipment and protect your eyes.

What I mean is do not use welder's glass to view the Sun. Surely that is easy to understand?

Solar viewing requires specialised solar filters. Those are the only things you should use to view the Sun otherwise you could end up being blind.

This is a UK site that shows quite a lot of solar filters that you can use for your telescope. Note that the solar glasses are to look directly at the sun with during an eclipse only, not through any telescope as the heat from the telescope eyepiece end would blow a hole straight into the glasses and damage your eye). All other types of solar filters (except for some very expensive Lunt type filters that go into the diagonal on the telescope) fit on the end of your refractor in front of the main lens, or on a reflector at the large open end that lets the light in. Never use anything other than a dedicated solar filter to view the sun, and make sure by a visual check held up to a strong light source that there are no holes (no matter how small) in either the glass or the film used, otherwise serious damage will occur to your eye if used in a damaged state with any holes in to observe the sun.

The sun it self bid way over 2,0000000 candle power.

hehehe this if a funny thread

Well I am thinking latter down the road if getting a moon filter and other filters to see some detail in planets can you tell me which ones I should get?

Oh it say thread on to the barrel of the eye piece....

Yes, all filters either thread into the EP directly, or sometimes directly onto the front end of a diagonal too. Your EP's should have an internal thread on the barrel to screw in any 1.25" filters. If they don't you would need to get EPs that do have threads to do this, of perhaps get a filter wheel perhaps to use instead that sits in between your diagonal and the EP itself.

There's a good general guide to colour filters at http://agenaastro.com/choosing-a-color-planetary-filter.html  and a more detailed analysis including some of the more specialised filters at http://sas-sky.org/wp-content/uploads/2011/09/SAS-The-Use-of-Astronomical-Filters1.pdf

Be aware that often you won't see tremendous differences with filters but with experience you can often tease out a little more detail. For telescopes with smaller apertures such as yours, it's probably best to avoid the darker filters. 82A Light Blue is one of the more useful colour filters.
