Subject: ETX first version Sent: Saturday, April 15, 2006 07:08:25 From: Andr Luiz Tietbhl Ramos (email@example.com) 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. Sincerely, Andr Luiz Tietbhl Ramos, M.Sc. Ph.D. Candidate Virginia Tech Professor - Dept. Mechanical and Mechatronics Eng. PUC/RSMike 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? Sent: Wednesday, April 5, 2006 09:00:45 From: FORGIEL Bob (BFORGIEL@fillontech.com) 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.) Thanks Bob Forgiel Rhode IslandMike 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.
