Quote: I'll try to see if the problem resolves by changing the worm position. If it does, it means that I should also be looking for a precision worm gear already for this mount?!
Quote:Thanks, John. I didn't even power up the mount yet. I only checked the mechanicals. I discovered the anomaly within 15 minutes of unpacking - Short lived glee! To test it, I'll have to solder connectors to a 13.8VDC 5A supply to power it up. I'll try to see if the problem resolves by changing the worm position. If it does, it means that I should also be looking for a precision worm gear already for this mount?!

Quote:Ed,I have the "white" version of this mount and based upon my use of it this past weekend, the accuracy of its tracking exceeded my expectations. I was in A/A mode with a C9.25" OTA and I was successful at observing targets on the monitor using my MallinCam with up to 2 minute unguided exposures.I would expect no difference in the results with the Orion version.Jack Huerkamp
Quote:Many thanks John, Ed, Martin, Brian, Skrenlin, and Jack! I powered it up and rotated the RA position until I found a firmer position in the center, but 90 degrees from center there is still a slight wobble when I try to rock it back and forth. The amount of wobble is mostly felt in one's hands rather than something that is grossly visible. You guys are right, it does feel like the gear has a slight play within the worm assembly. The amount of movement is just slight enough that I can just barely detect the pointer in the setting circle move when I rock it. I wasn't expecting any play when I bought it. I also assumed a slight nudge or any wind might be detrimental if I do AP in the presence of any play in the RA axis...So, you guys think I should keep the mount? Can you guys please check YOUR mounts to see if you can FEEL AND SEE any nudge when you try to rock it back and forth in the RA axis?BTW, I couldn't find the link for the Atlas worm adjustment.Does anyone know if the G11 has any play in the RA or DEC axes?Ed, I just received the T-Rex today. Thank you! I haven't opened it yet as I am trying to solve this first. This is the $2,300 AZ EQ-6. This is first astronomical gear I've owned as I bought everything from scratch.. Yikes, I've already spent $17,000 on top of the line equipment: TEC 140, Baader VF, Maxbright Diagonal, Mk V bino, all Televue and XW EPs, Lumicon filters, Starseek, custom cases, AZ EQ-6, T-Rex, etc... Spending $6k++ for a mount would put me in the $20k range. That's a lot for a fledgling hobby. That's why I went with the AZ EQ-6 and also for portability. I also wanted a dedicated alt-az too without CW like the T-Rex because I plan to use that mode 70% of the time, 25% GEM, and maybe 5% AP.Thanks,George

Quote:Questions:1. Are any of you getting this wobble or nudge in the RA axis?2. Does the G11 exhibit wobble in any axes?3. Does the Mach1 exhibit any wobble? I do like Astro-physics - real classy group on the phone.
Quote:Thanks a million everyone! I followed the instructions on Astro Baby. 1/4 turn is all it took and the RA axis is now rock solid. I checked it 360 degrees to be sure and there is no wobble. This one's a keeper guyzos!Ed, I unpacked the T-Rex and just assembled it. I am going to use it with the AZ EQ-6 Tripod. Questions:1. I can't figure out how to attached the EQ-6 pier extension, the screw engages the T-Rex by only 1/8". That's not enough. Photo below. Any recommendations? 2. How is the best way to attach the quick slew handle.3. Should I be removing the screwed pin on the tripod?Here are the photos from this evening: http://www.flickr.com/photos/94098724@N03/?saved=1
