Subject: Re: ETX Service Manual Sent: Tuesday, December 9, 2008 10:22:31 From: Brian Jones (email@example.com) The Dec Setting Circle Scale is not rotating with the OTA, it stays in the same position if the OTA is raised or lowered. I wondered if it would be easy to sort out (it doesn't affect the performance of the scope at all) and removed the four hex-headed bolts in the black plastic at the rear of the OTA (2 each on the left and right sides), hoping that the OTA would then slide out of the fork mount but I couldn't move the OTA. Not wishing to force it at all (in case I broke something) I was looking for a service manual to see how to release the OTA to get at the Dec Setting Circle and see what wants fixing. If you know how to disassemble the OTA from the mount, I'd be grateful. Kind regards BrianMike here: You were on the right track to remove the OTA. See the bottom of this page: http://www.weasner.com/etx/90ec_comments.html. However, you may not need to remove the OTA to fix the problem. See the article "DEC Scale modification" on the Helpful Information: Telescope Tech Tips page. Although that article is not for the ETX-90RA, it may still get you pointed in the right direction.
Subject: ETX 90 RA Sent: Sunday, December 7, 2008 14:32:46 From: Nancy W. Burgess (firstname.lastname@example.org) In searching for a manual (instructions) for the model M (90 RA) Meade Telescope which my brother gave us, I came upon your website. I was wondering if you might know where I can find a copy of a manual for this model? I would be willing to pay for a copy. Thank you very much! Sincerely, Nancy BurgessMike here: The ETX-90RA manual is online at Meade's site: http://meade.com/manuals/etx/index.html
Thank you for the speedy reply! I had a trawl through the site but couldn't find anything specific to my query. Thanks to your email, I'll have another go. Thanks Mike Clear Skies! BrianMike here: The ETX-90RA was originally called just the "ETX" or the "ETX Astro" or the "ETX Astro Model M". So what info were you looking for?
