What eyepiece combos are you using to view Mars in your ETX?  Although I
imagine you use a more powerful ETX than my 90.  Anyway I wanted to
report that I tonight saw Mars for the first real time in all its glory,
with a 9.7mm Super Plossl WITH Barlow (258X!!)  No, it wasn't quite
crisp focus, but it still afforded more detail to the eye than without
the Barlow, even though the 9.7mm alone was nice and crisp.  Saw the
southern ice cap, nice surface detail, really amazing.  I really
couldn't believe what I was seeing.  Some people told me 9.7mm + barlow
was not worth trying for my scope, BOY were they wrong.  I think you
have to push it to find the best balance between crispness and size.  Do
you think it would be worth investing in any other eyepieces to view
Mars more clearly through my ETX?  Maybe the 6.4?  (Only other I have is
the 26mm).  Well thanks.
Mike here: Depending upon where you live, Mars may be very low in the sky. THat means that seeing won't be very good. If you are happy with the views, why change. Keep in mind the maxiumum theoretical magnification for the ETX-90 (180X); yes it can be exceeded (which I do quite regularly) on bright objects. I do have the ETX-90.

Just purchased one off ebay and would like to know if you can upgrade
the motor mount so that it will perform like the EC?

Thanks for any feedback.............Left the hobby about 10 years ago
and sold my 10" SC to a local college.

I have an older ETX-90 RA. 1997 vintage model.  could you please direct
me to the area of your web site that address's the problem of slop in
the RA knob. (the Ra knob does not ingage immediately when turned,seems
loose)  I called MEADE today (7-9-03) and got a hold of chris ext.500
and he told me only thing to do was to ship it back to meade corp. and
let them look at the problem.  I thought I remembered something on your
site dealing with this problem years ago.
Thanks,
 Tim Smith

A quick question that I wanted to see if you could help me with. I have
an ETX90 and am wanting to get the most out of it for seeing Mars at its
best. I am considering buying an eyepiece color filter to enhance
details of the planet. If I were to buy only one filter do you know
which color would be best to get for the ETX90? Thanks

--- Ronnie Blazer II
Mike here: The filters that work best with Mars are too dark for use with the ETX-90 due to its smaller aperture. But if you want to try, see the Orion Telescopes and Binoculars filters page:

I just wonder whether it's normal that the 26mm eyepiece with filter
gets to long in the ETX-90EC, i.e it stops before it fully fits in.

Thanks a lot for your reply and best regards,

Mike here: That's OK.
