The mount handles the scope very well but mounting it with the 1/4 - 20 holes in the base of the ota, puts the eyepiece at the side of the scope. I'd like to use rings to mount the scope so as to get the eyepiece back to its normal orientation but can't find any rings that the vendors think will fit. I priced a set from a site where the owner will custom make the rings but frankly, I don't want to pay his prices. Does anyone know a source (or do you have a clever DIY approach) of rings to mount the tube?? Please don't suggest using a visual back. I've considered, and rejected, that option. -------------------- Ken ST80 SV80ED ETX90 (Deforked) Orion XT8 Post Extras:       Arthur Dent Galactic Hitch-Hiker Reged: 10/23/08 Posts: 1150 Loc: South Yorkshire, UK Re: ETX 90 mounting rings??? [Re: Kfrank]       #3190433 - 06/30/09 07:00 AM Edit   Reply   Quote Quick Reply   Hi guys, Similar query to Ken's above although I have an ETX-105 that has had RA drive problems from day 1 (it was a s/hand scope). Planning to mount it on a NexStar SE mount to start with, then aiming for a GEM later on. As Ken said, the mounting holes on the ETX are underneath which would mean that to EP/diagonal is at the 3pm position. Apart from having a custom 'L' bracket made from a block of solid aluminium, are there any other ways of mounting it on my NexStar SE mount as the purchase of a GEM is some way off yet.

I have several sets of each brand's rings.

[Re: nighty]       #3204245 - 07/07/09 01:47 PM Edit   Reply   Quote Quick Reply   Thanks folks. The problem is solved!! I looked at a variety of places for scope rings. The ETX90 ota has a diameter of just over 4". Talking with Manish at Agena (who tried some rings out on his ETX90) I discovered that 4" rings won't work (too small) and the 4.2" rings readily available are just to big to give a secure fit, even with additional felt. This leaves custom rings and I didn't want to pay the freight for this option. Today I talked with Larry at Universal Astronomics. Looks like one of his binocular mounting brackets will do the job. The bracket is designed to work with the MicroStar basic mount that I have. For a very reasonable charge, Larry agreed to remove the captive 14x20 screw for mounting the binoculars and mill a slot in the bracket to accommodate the mounting holes in the bottom of the ota. Problem solved and for a lot less than a pair of custom rings. Thanks Larry and thanks to all for the suggestions. -------------------- Ken ST80 SV80ED ETX90 (Deforked) Orion XT8 Post Extras:       Bob Myler sage Reged: 05/18/06 Posts: 215 Re: ETX 90 mounting rings???
