Thanks GuitsBoy, I apologize, I did not read your first post detailed enough as I was too excited to see the simpler approach over rockmover. When I read it again I realized it was stabilized. I agree

Hi Brent - We're getting close, but I still want to star test and make sure it runs well.? I already discovered one oversight.? The big pulley was off center by 1mm, which means it could potentially

There are a number of reasons to change out the gearbox from Losmandy. I have the original ones with plastic tabs, their modified version and the 25:1 McLennan. I built my observatory early January in

Hi! Here's the description of the improved feature in a discussion thread: https://www.indilib.org/forum/general/8602-new-polar-alignment-scheme-and-features.html#65724 I hope this is useful. I also

Hi David, Was just looking through your log with PECPrep and this looks like a guided run. For a good mount analysis you need to restart PHD2 and do unguided output. Here you must exit PHD2, not just

Thanks for the details. My view of the polar region is limited, and I can’t get below about 45? altitude around the celestial equator so drift alignment is difficult. This KStars procedure is very

HI Dwight you're not late to the party at all :) There are too many options to cover them all, but it's good to hear about this one. if you happen to know and can recommend a good tutorial on this

Think of it as your car engine oil change. How often, how far, how hard do you drive it. Water contamination or corrosion is what to look for whether it's always out or stored indoors. Always good to

That's the whole point behind the idea of changing the gear ratio. Easier on the motors and smoother running.

Peter, The ABEC bearing grades have nothing to do with external dimensions. The ABEC grade is a standardized set of internal bearing tolerances. The normal commercial bearing grade is ABEC-3 If your

I use the my main scope for the alignment procedure, fl=1000mm on a 3.8um sensor, or about 0.78"/pixel.? I've done it with my guide scope (253mm, 2.9um, 2.36"/pixel) and it also works fine. I can't

Hi Edward.? Yes, I understand.? My issue is that one side can be pulled out along the axis of the coupler while the other side is tight with no play. ------------------------ Jim W Phoenix, AZ. USA

Jim, In case it wasn't clear, an Oldham coupler is *supposed* to slip along those groves yet not have play when the shaft is twisted. The purpose of an Oldham is to allow connection of two shaft that

Thanks for the tip, Dwight. What is the field of view or pixel scale of the camera that you use for the alignment? -Les

I use it too, on a Pi4b with an OnStep controller on my G11S.? Why do you need multiple iterations?? I use it near the NCP and 1 iteration works, it's a one shot method.? However one time I was off

Probably late to the party, seeing as Brian Valente started uploading tutorial videos on the subject.? Thought I'd share here in case others might find the information useful. I use Ekos/KStars,

OK ------------------------ Jim W Phoenix, AZ. USA

Chip, Bearing grade I think has a lot to do with the tolerances that affect the seating in the one piece worm (oxymoron) blocks a relative to the relative worm shaft, and if there is play.? At least

Hi All, I seem to keep repeating the same thing over and over regarding the 76 second PE bump but people don't seem to know how to find this information here in the groups. I didn't invent this but I
