The upright sections are hinged so they fold down out of the way when not in use. If you are unsure of where to read the time, notice that the line that says noon points straight Southand the sun is more or less directly South at 12pm. I made the finder below from two pieces of flat PVC plastic and a piece of clear Plexiglas, which I frosted with fine sandpaper to make a screen. These are represented by the heavy solid lines running vertically. One nice variant is to open the body of the finder so you can look at the bright spot on the screen from above. After you’ve found the Sun in the scope for the first time with the finder attached, put a black dot in the center of the bright spot with a felt marker and you’ll have no trouble finding the Sun again. When aimed at the Sun, a bright spot of light shines on the white plastic. Cap the front end and drill a small ( 1 / 16-to- 1 / 8-inch) hole in the middle of the cap, then stretch a section of white plastic bag across the back. Designing it to fit on your regular finder’s mount is a good strategy, since you won’t be using that finder by day anyway.Ī 4- or 5-inch length of 1-inch-diameter PVC pipe makes a good finder body. You’re better off building a finder that you can mount solidly on your scope so it’ll remain aligned from use to use. Masking tape isn’t very elegant, and it’s hard to get the two tabs precisely aligned. Center it up, and you’re on target.Ĭut the front tab into an arrow shape with its point half as high as the rear tab and you get the same effect with a shadow instead of a bright spot. Poke a hole in the middle of the front tab, and move the scope around until the ray of light shining through the front tab hits the back tab. Put another tab a foot or two back, in line with the one on the front. Stick one on the front edge of your scope with an inch-long tab standing out. The tool most likely to be used when measuring the length of a very long roof would be a a. The simplest finder I’ve seen consists of two tabs of masking tape. Fall protection must be worn when working at heights of a. You can either cast a shadow onto a target or cast a beam of light on a target. There are two basic ways, and both use the Sun as part of the system. Until you’ve tried it, you’d be amazed at how difficult it is to aim a telescope at the Sun without some kind of finder. With the filter on your scope, you won’t see any glow through the eyepiece until you’re right on it. (Seriously, don’t do that.) The Sun is too bright to even sight down the your telescope’s tube at safely. The Solar Pathfinder can be purchased as a standalone device or can be purchased with a case and tripod. This is a great tool for homeowners and installers alike and is an industry go-to tool for site analysis. And it’s too bright to look at with your Telrad or optical finder. The Solar Pathfinder is a must have site analysis tool for anyone who is keen to find the most optimal location for their solar array. The detergent jug spout includes a convenient target frame.Ĭome on, how hard can it be? It’s right there, big and bright and half a degree acro.
