Will do!
I assume this sort of gadget isn't affected if it gets a magnetic strip stuck on it so I can clip it to my scope tube? I know Rod's is held on magnetically ... I have no idea how these actually work or if anything in it can be affected by magnets. I only know there is so much metal in our building I cannot use a compass to line up so will have to go by visual sighting -hopefully using Polaris- to align everything.

Just by way of clarification, my digital level is held on its mounting bracket by velcro. It was the original analog inclinometer that was magnetically mounted.

Heads Up - Lidl UK - Digimeter new [Re: rnabholz]
      #1341481 - 01/05/07 05:56 AM

UK residents looking for cheap digital meter - Lidl has one coming up for sale from 11/1 for 24.99 UK pounds.
Having got Allen keys as a Christmas present (how sad?!) I have now released meter from the level!!
Thanks for the correction Rod. I played with the magnets around the meter and it didnt appear to affect it but I may have to use velcro anyway since I hid my magnets away so toddler wouldn't find them - now can't remember where they are!
Now waiting for some clear skies!
Happy New Year to all - let's hope we see some great things this year!

D:rzeus: Happy New Year to you! Well, Allen keys, hmmm, they did let you release the meter from the level, didn't they?

Let us know how your "push-to" system goes.

Carol - Your $12 "Push-To" is right on the mark - That's exactly what I paid for mine! Although I must say working I for a newspaper did some some advantages.
While I gathered all of the needed materials during my week's vacation between Christmas and New Year, I wasn't able to complete the project until last night (too many "honey-do" projects around the house!).
First, I printed the degree circles at work. We don't have a printer quite large enough to print the entire 19-inch circle, so I ended up doing it "piece meal" in thirds. We have an old light table (from our old "hot wax" days of pasting up the newspaper prior to pagination) so I was able to carefully align the three pieces. Luckily, we also have a double-sided laminator.
I affixed the circle to the base with double-sided duct tape (yes, duct tape - it's a guy thing!)
We also had some strapping steel laying around at work so I used about eight inches of that on the front of the bottom base board attached with three stainless steel screws. I've had no luck in finding clock hands up here, so for the time being I found a package with four thin rectangular-shaped magnets ($1) to point the degrees and align with Polaris.
Now for the inclinometer. I has hoping to find a digital one, but again, living "Up North", no luck. After going to three stores, I finally found a Mayes level and angle finder used to deterine roof slopes and grades ($11). It's magnetic and is attached to the top of the scope (I wonder if the company knows these can be used as a "telescope accessory" ).
I'll use my old Boy Scout compass to determine north and I have a very small level to check the base. Plus the Stellarium program on my laptop gives Alt/Az coordinates.
Now all I need is for these clouds to clear out so I can give the new system a trial run (of course it's cloudy, I'm also waiting on delivery of two nebula filters I've ordered)!!
Thanks again for the great post and I'm looking forward to trying this out (it looks like I may have an opening tonight).

Being in the UK i plan on purchasing the lidl level for use with my system. I'm currently using a dial inclinometer but hopefully the digital one will be much more acurate

John: Congratulations! I'm so glad you found the post useful; you will be amazed at the accuracy of this simple addition.

Please let us know how your first night viewing with the $12 Push-to System works.

We better not let the inclinometer manufacturers know it's an Astronomy accessory, or the price will sky rocket!

Thanks for the kind words, also!

Carol

John,

Nice job! You'll find that this system will make a BIG difference in how you find objects in the night sky. Using this system along with a good planning software package, will certainly make viewing the night sky more enjoyable. Good luck and let us know how it works for you.

Is that a small head nail painted orange? And I agree with Carol, nice job!

Thanks Carol and John for the kind words!

Woodworking is just one of my favorite past times, as well as astronomy. I have a second base that I got from a freind, so what I did was to cut the notch out of the side of the top board, and covered the cut surface with a piece of the "edging" from one of the spear pieces that I had. I made it look as if it was made that way from the manufacturer of the base.

Yes John, that is a small "finish" nail that I bent and placed between (2) small magnets, one on each side of the nail. They are held together with epoxy glue and finished with black and red enamal paint. It works really well. I am able to see it in the dark to adjust it as need be. I did exactly the same thing on my 8" Dob as well.

Well after quite a while and contacting Carol for some information i have finally finished my version of the Push-To. As i had a 12" GSO scope i already decided to replace the ordinary chipboard base by using it as a template and making it from plywood. So i had the circles printed/laminated and constructed the base, i also put full circle laminex (formica) under the top circle and new Teflon bearings, changed the plastic handle to Aluminium and inserted a bubble level into the base. I made adjustable screw feet to help with leveling and added side braces to help with stability. All up a pretty steep learning curve for me as i had no previous experience especially with a router and large circles. The mount is not perfect and there are quite a few mistakes but noted and in future i will have learned and improved (i Hope)
I also tracked down a digital inclinometer and have fitted it to a timber dovetail i made to take the place of the finderscope i can buy a new foot plate and fit it to the tube later so i can replace the finderscope.
There are so many innovations and really professional quality work shown on this project and i just wanted to show my version and say a big thanks to Carol (and others for contributions)
