Hello John, I didn't fully understand you question about clutch knobs. Can you elaborate on it? I will work on the polar alignment and balancing when I take my scope out this weekend. -Hemendra

How accurate does the polar alignment need to be for the goto? I'm just doing visual astronomy.

My pulley ratio is 2.5 : 1 (40 GT2 pulley on mount drive and 16 GT2 pulley on motor axis).

Hi Khalid, The RA and DEC axis move smoothly without the 8 inch OTA. When I put on the 8 inch scope, the RA axis slow motion knob becomes a bit stiff but I never expected the stepper motor would lose

Hi John, Khalid, When I said stepper motors were not hot, I meant they were slightly warmish to touch. Nothing significantly hot. My stepper motors are 0.9 degree Nema 17, 0.9A motors with an LV8729 (

Sure. I have access to a lightweight 120mm OTA. I will give it a try.

I have connected motors to the worms via GT2 pulleys and timing belts and the reduction ratio is 2.5:1. The OTA is quite heavy at 16.5lbs and the mount is rated for 20lbs. How do I verify if it is ski

I checked my configuration. It is set to 32 micro steps. How large the error was in your case? In my case the star comes near the outer circle of the finderscope. So I'm using the error is around 5-10

Hi All, I took my telescope out again for testing last night. The Wi-Fi connection is stable now and mount can now actually find the alignment stars with decent accuracy during the alignment process.

Let's say I will use the Stellarium Desktop. The app has a "sync" button. After slewing to the alignment Star I will press this sync button. The web server also has an "Accept" button next to the star
