Chasing my tail on a balance problem with my imaging rig. I have everything up on the scope to take advantage of the through-the-mount cable system. Couple of videos below to show my problem.
I balanced in RA and Dec horizontal and then noticed the scope does this in Dec with mount in the zero position:
So I moved the RDF to the opposite side, and added a small amount of counter weight near the focus control box. So then I got this. Nice!
But when I released the RA clutch, this happened. Not nice!
Here another shot of Dec balanced with RA horizontal:
So I'm in a bit of a pickle. I can remove the small counterweight (taped together washers) and get RA balanced where it doesn't fall off to the west, but if I do that then the objective end of the scope falls off to the east as in the video above (with mount in zero position). To me its pretty clear I have more weight on the west side of the OTA (focus motor, controller, and RDF). So I'm not sure why I needed even more weight on that side to keep the dec from swinging the objective end off to the east.
I've had an endless stream of equipment issues (the latest was a failure of my new digifire 12 requiring new circuit board). Very little time under the stars this year, and I'm fighting off frustration the best I can. I feel like I've got this rig close to where I can image pretty happily for a while, but this balance thing is driving me crazy. If i can't get both perfectly balanced, which one should I pick?
BTW, I have more counterweights coming tomorrow to get the weight further up the bar. I have about 32lbs on the saddle right now.
