I came up with this idea after being frustrated at how long it was taking to get a precise polar alignment on my Skyview Pro. We rent our house in Texas because I am only here on shore duty. We can't make any permanent modifications to the yard. I still wanted to do something so I came up with a plan.

I went to Home Depot and bought a 2 foot long section of PVC pipe about 1.5" in diameter. I cut it into three lengths and made sure each section had a sharp 45 degree cut. I then did a daytime polar alignment of the Skyview Pro in order to get everything into a rough position.

With the help of my wife I then drove the pieces of PVC pipe into the lawn until they were flush with the surface. This way the lawnmower doesn't wipe them out and it won't nick the blade either.

I then placed the Skyview Pro feet into these holes:

Once the Skyview Pro is set up it then takes me roughly 30 seconds to tweak the latitude and azimuth screws. It has never taken me more than a minute to get Polaris EXACTLY in the spot it is supposed to be in:

To aid in finding these PVC pipes I have two pieces of wood and a piece of scrap aluminum painted blue. I stick these in the PVC pipes if the EQ is not there:

Of course I remove them when I am mowing the lawn. Not bad for less than $3 eh? I put this in the Beginner's forum to help others out. I bet a few more experienced members will benefit from it too.

Clear skies!

Cool beans. I set three pavers in my yard with spots marked on them where I should set the tripod legs. Over the years they've sunk in a bit and the grass has grown over their edges so they're kinda hidden and out of sight.

If I did this with a deeper hole to prevent frost heave,and just poured concrete with a dent/tube to allow the leg ends to rest in.. would that work also

Sure. Just call before you dig! Don't want to hit an electrical or cable line!

Great idea, once all this snow melts I'm going to try the same thing.

Very nice. I might have to do something similar to this.

I just wanted to make a note that the PVC pipe can be from 1.25 to 1.5 inches in diameter. This of course depends on how big the tripod feet are. I bought more PVC pipe to align my starfinder EQ. It cost a whopping 3 dollars for 2 feet of it. I will be polar aligning that mount very soon as well.
