Subject:	Purchasing a Meade ETX 90

Hi, Im 14 and ive had my eye on this telescope for a while, I love
astronmy and space and I`ve always wanted to observe it myself. I wanted
to know what all the different lenses are for. Which lense can see the
farthest with good detail? Would I be able to observe deep space images
such as nebulas and galaxies? and where can I find a used or new
telescope for a cheap price?
Mike here: The ETX-90 is a fine telescope. You will be able to view the Moon, planets, some nebulae and galaxies. Just keep in mind that your eye will not see all the colors and details that you see in photographs. And since the ETX-90 is a small telescope, objects, especially faint ones, will appear dim, fuzzy, and without color. That said, you can read about the ETX-90 on the Helpful Information: Buyer/New User Tips page as well as on the Helpful Information: User Observations page. For info on eyepieces, see the Helpful Information: Buyer/New User Tips page as well as the Accessory Reviews: Eyepieces page. Meade has rebates on new ETX models (ends today) available from Meade dealers such as Oceanside Photo and Telescope (; for used telescopes you can check or as well as the For Sale page on my ETX Site.


Do you think this is a good scope to start on? or do you recommend
another? I`ve had a small tasco telescope, but I could really only view
the moon with it. I need something between $100-$450,because of child
labor laws I have to rely on Christmas and Birthday money lol. The
ETX-90 is the best I could find, but you seem to be much more
experienced in this area so Id like to get an experts opinion.
                                                     Thanks, Brian
Mike here: As you can read on those pages on my ETX Site, the ETX-90 is a fine telescope. But whether it will meet your expectations, only you can say. It will likely perform better than your previous telescope. I still like my ETX-90 (purchased in 1996) even though I have many other telescopes now as well.
Subject:	ETX base

I bought an ETX in 1996 therefore it does no have the current base,
which is much better btw.  I found this base for sale: ETX 90 RA
telescope base motor and hardware (eBay:

If I buy it would it fit my 1st version ETX?  Any special setup

Thank you,

Andr Luiz
Mike here: That is the "guts" from the original, circa 1996, ETX model (now known as the ETX-90RA). It is from the same model as you have. If you wanted it to upgrade to an AutoStar capable ETX, this won't do it. You would have to get an entire ETX "EC" mount with the fork arms.


TNX FOR THE QUICK REPLY :-)  Hmm Im assuming then only the optical tube
is the same, correct?  My question would be more specific: is this base
better than the original one in terms of its star "gazing" capability?

Would you where I could find an ETX "EC" mount please?

Thank you,

Mike here: The EC (or AT; they are the same) base is better in that there is full electric control of both axes. As to finding one, you could try Telescope Warehouse (link on the Astronomy Links page) or eBay.


TNX AGAIN FOR ANOTHER QUICK REPLY!  Telescope Warehouse does no have it.
Would be able to suggest another store?

Thank you,

Andr Luiz Tietbhl Ramos, M.Sc.
Mike here: Other than eBay, you could try Astromart or perhaps the OPT web site classifieds.
