So getting good GOTO results I think tells us that the mechanical basics are solid and all you really need to do is fine tune your autoguiding. Leave the mount hardware alone for now and look at the

Hi Chip, Understood. Despite the not-so-good RA guiding the accuracy of the pointing was very good. Yue

Yue, The Losmandy GM811 is not an EQ6 and you need to do things a bit differently to find the mount's sweet spot. Every Losmamdy mount is capable of a slightly different different minimum PE value.

Ok finally got a chance to test my 811G last night, and honestly, not as I expected. Not as bad as 'disappointed' but not as what I 'expected'. The DEC turned out smooth, no issues at all however the

Estimated tracking resolution at 32 ?steps is 0.58 arcsec/sec, 68 is 0.48 and StealthCrop interpolated 256 steps/step is 0.42. I've seen PEC plots that seem to bear out the estimates. We're planning

Yep, safety limits will also do that, and I didn’t think of that option either so, double doh! Lol You have a couple of options to take the mount off the safety limits. You can use the hand

Doh! Thanks, Jonathan. I didn't even look at the HC this morning. I just went out and checked and the mount had reached a safety limit. Anyone, I'm guessing here but once that limit is reached, does

Hi Joel, I may not be of much help but there are a couple of things you can check. If you have your hand controller connected try issuing a park command from it. Make sure it’s not reporting a motor

Twice over the past week, my G11g has just stopped - not powered off, stopped. Once was during setup while I was trying to slew to a target before my session and last night about four hours into my

Even using 0.9.degree (400 step) stepper motors and the maximum possible micro steps a direct drive stepper Losmandy G11 has relatively low resolution. Once you use a.more realistic number of micro

I was curious about the CQ350 but went with the EQ8-R Pro. My EQ6-R pro is now my portable mount.

That's what I meant.? The mount was an iOptron GEM45 and it has a 1.5" peak-to-peak oscillation in RA with a period of, if memory serves me right, something like 0.7 second.? (Since a 1.5" p-p

Hi Mike, Can you explain what you mean by a "period of a full set of microsteps?" I can see that meaning the period of time it takes the motor to complete a microstepped full step. But in my example

Michael, Micro step position does vary but I'm not sure it represents a significant issue; this not accumulating during guiding.? The issue appearing like corrected backlash.? And it cannot

Yes, but it remains the case that torque is not the same across the entire microstep cycle, leading to slight speeding up and slowing down.? We're not talking about lacking the torque to move the

You can increase torque by using a larger to smaller belt hub, which is the same as any large to small gear ratio. -- Brendan
