Subject:	ETX first version

From:	Andr Luiz Tietbhl Ramos (
Reading your excellent website about the great wonder ETX I thought
about introducing two questions to you please.  I bought a first version
ETX just like you when I lived in the USA.  Unfortunately in Brazil the
only support available is the Meade reseller nothing else you are on
your own.  My questions are below:
1 - Where could I find a tripod for the ETX?
2 - Is there any way to purchase just the base of the new ETX to "adapt"
it in the older ETX?
Thank you.

Mike here: Many tripods will work. See the Accessory Reviews: Tripods page, or if you want to make your own mount, see the Helpful Information: Telescope Tech Tips page. As to a base, try a used parts place (like eBay).
Subject:	can the ETX90 gather enough light to use #58 green filter?

From:	FORGIEL Bob (
I have been reading about the various color filters. On your site there
is a page concerning Jupiter and the mention of the #58 green filter as
being  a good filter for Jupiter. Now, my question is, can the ETX 90
gather enough light for the darker #58 green filter to be used or should
I be looking at a lighter green that will pass more light?  (Please
excuse me if this is a dumb question because I'm a telescope virgin that
is still learning.)

Mike here: I personally haven't used the dark green filter but have used the #56 light green one (see the Accessory Reviews: Filters page). On bright objects like Jupiter you might be OK although the image will be dim, especially as you increase the magnification.
