Made a couple of minor changes... Painted the worm block assembly black. Changed to button head socket screws. Added very thin washers so the button head screws don't get stuck in the paint. Added

Does it have to be the "blessed" Losmandy way?? Which is by polar scope or Gemini I suppose. I would suggest that there are several of us using a Pi and OnStep so you may want to bring that up too.?

Another indoor trialing trick is to switch the tracking mode to “terrestrial”. you can slew around but dont have to worry about it tracking into furniture. That mode will stick across a gemini

JMD: You posed this puzzle: How to eliminate or minimize the variation in polar alignment when you loosen and re-tighten the AZ and EL locking bolts. _______ Here is what I did to help minimize this

It’s complicated. Because refraction varies continuously across the sky, there is no combination of polar alignment and tracking rate that will give perfect tracking everywhere. In fact, there is no

Hi Brian! I use Pole master and generally that is pretty good. ?The ONE area that I find I have to really pay attention to is when I go to tighten the Alt and Az axis back down. ?If I do not take

Hello Henk - Thanks for your comments.? I'm of course familiar with your SLW modifications, and were part of the inspiration in trying this for myself.? Your use of the sideways spring to apply both

What I would like to see some day is: Polar Alignment, part 2 - very accurate polar alignment I can get extremely precise PA with sharpcap, but the accuracy seems to be a bit off since I still get a

Whew!? Good to hear.? Thank you Michael. Regards, John On Sat, 22 May 2021 at 3:12 pm, Michael Herman<mherman346@...> wrote: John, There are several protections built into the Gemini system.

John, There are several protections built into the Gemini system. If the motor gets stuck (or worm gear jams, or scope is trapped by a wall or a snagged cable), the Gemini is designed to detect this

Responding to this old post as a similar thing happened to me last night. I have a G11G with a SLW on the RA assembly.? I was trialing N.I.N.A. indoors just to check connection to my mount, guider,

My input Brian One of My factory installed level seem to be inaccurate – so where to place the level ? - a bubble in the center of the base? Over the top edge of the azimuth screw and along the top

Hi Tony that looks great.? The basic idea is not that different from my humble construct below (for DEC) Namely, both blocks are screwed fixed against the aluminum cover (and are aligned to prevent

Hi Tony, Marc Aragnou in Australia also made his own SLW. He used one or more rubber O-rings as springs. They are a shorter range spring. I wondered if the rubber would be temperature dependent or dry

Hi Michael - Please, no apologies necessary.? I'm one to find the humor in a good autocorrect fail, but not quite sure I've spotted the gaffe. Regardless, no worries at all, I never gave it a second

...sorry for the not so humerous typos... I meant your ... clever design... I don't know how the Android programmers made the autocorrect pick the worst possible words to use. Maybe the Android system

Very nice work. Please put your steps and photos into a PDF, as the email will become lost over time. You can then upload your PDF instructions into the group files....and you will be famous forever!

Great subject Brian, thank you for taking this on.?I got a G11 in part because the machining quality and precision allows the mount to get good polar alignment without the need to further correct
