Hello Everyone, I'm new to this stuff so bare with me. I expressed intrest of star gazing to a few co workers and one offered to give me a telescope. Its a Meade 4455d model. Its pretty dirty, but cleanable. Anyone have any advise on to clean the mirrors and how hard it is to ajust them after you replace them? I haven't done anything yet, will wait for a responce :-).

I think its a 4.5 in Reflecting scope. It doesn't have any eye pieces or finder, so I will need to buy those. What should I look for as far as these go? I don't have much money so anything cheap that is good:-).
Finally does anyone know if this telescope will be good for a starter? Will I be able to see planets, Galaxys and that type of stuff? Thanks in advance

This is a 114mm reflector that is the in the 900mm focal length? How long is the scope physically? About 20 inches or 36".

In the reflectors forum, there are discussions about cleaning mirrors and also about collimation. Read them both, they will answer your questions.

As far as eyepieces. somewhere between 25mm and 32mm for a low mag eyepiece and maybe a 8-10mm eyepiece for higher mags. I'm sure others will give opinions as well.

Welcome to astronomy!

That's a great way to start and you have a generous friend. Do you have a pic to show us?

Don't be afraid about cleaning the mirror - washing is more like it. While the mirror is out, don't be afraid to gie a good wipe to everything, to avoid dust from falling back on a freshly cleaned mirror!

As for the eyepieces, I second Tom's motion. The kellner / SMAs and generic plossls are good bargain eyepieces. You can find them used for cheap on Astromart.com.

One thing you will need advice at first is collimating the scope, especially if you remove the mirror to clean it. Maybe you should ask your friend to show you around on using it.

Wow Thanks for all the great information. I think what I have decided to do is to buy a Dobsonian Scope. Many have recommended this type. The question Now I have is which one? There are 2 I am looking at,
1, is the By hardin Optical Deep Space Hunter® 10-inch Dobsonian Reflector Telescope site is here
http://www.hardinopt....com/dsh10.html

2, is By Orion SkyQuest™ XT10 Dobsonian Reflector Site is here
http://www.telescope...erID=338

Which on would you all recommend? This will be both for my wife and myself. She took me to an observitory last night and had a great time. I am now wanting to go on my own to explorer. I'll also probably join the local astronomy club. :-) Thanks for your help and advise
