[QUOTE="Binastro, post: 3176251, member: 111403"] . Never having tried the colander method of projection, I thought I should try it as it was a sunny day today. I didn't know if we had one, so I tried the sink drainer that goes over the sinkhole. This has many holes. . But I didn't have any luck. Then I thought of using a tea strainer or tea infuser I think they're called, but I haven't done that yet. Not being at home in the kitchen, I asked if we had a colander, and 2 were magically found. I just tried one, and the reason it didn't work in the kitchen was that the projection distance was far too short at 1 m. The most I could move to was 2 m and the images of the Sun began to appear. Measuring the holes, they are 5 mm across, so I think that I need to have a clear run of 5 to 7 m. The bottom of the colander has seven holes, a central one and six equally spaced holes around it. I will have to wait till the sun is in the right place so I can get the proper, much longer, projection distance. Here's hoping. P. S. At 3 to 4 m projection distance, the sun's images are beginning to look quite reasonable. I think that this distance would probably show the Crescent Sun quite well during the eclipse. For better resolution, if you have 5 to 7 m with a colander that has 5 mm holes one should get good results. I suppose that different colanders have different size holes? [/QUOTE]
