I had an ETX90 for a little while and liked it a lot, ended up giving it to my son so he could use it with his DSLR.
I have a 90mm Orion that I have been using as a replacement, but have wanted to step up to a 125mm or 127mm and give the Orion to my folks for terrestrial use.
A member had an ETX 125 at a great price, so I picked it up. Looks to be in good shape overall.
Only issue is that the plastic housing that the OTA sits in rotates 90 degrees. Pulling it back towards the observer, it does not come off the OTA, at least not with the amount of force I've applied thus far. But the entire OTA rotates inside of the plastic rear assembly. Wondering if this will be an issue, and how to fix. My ETX90 definitely did not do this.
This unit is deforked. Is there an easy way, that is not quite as permanent as cement or industrial adhesive, to adapt a standard finder scope to it? The factory clip-in finder scope location is empty, and looks less than strong anyway, as far as using it to mount a more traditional finder.
Finally, I had been using the Orion with an AZ-GTi mount, and would love to put the 125 in its place. However, the ETX has a built-in diagonal that does not rotate. It does have a threaded hole at the rear, for a 45 degree diagonal generally. Is there an adapter I can buy that will thread onto that location and then provide a standard mounting tube for a traditional 90 degree diagonal, so I can mount the ETX (essentially sideways) to the AZ-GTi and still use eyepieces from a comfortable head position?
Thanks to all.
