\"\"<\/a>Over the weekend I took a break from JBOT amplifiers and did something I’ve been meaning to do for a long time: solar astronomy. I pulled out my old 4.5 inch Tasco reflector telescope and aimed it at old sol. I know, I know, this can be dangerous, but we were careful — note that Billy is standing on the other side of the business end of the telescope. In his hands is the paper onto which we projected the solar image. I’d always wondered how I would get the sun into the telescope’s field of view without risking my eyesight by using the finder scope. This turned out to be no trouble at all: I just looked at the shadow cast by the tube of the telescope and –using the shadow as my guide — moved the tub<\/span><\/span>e until it was lined up with the sun. We snapped a picture of our results. I think our crude effort compared very favorably with the picture from NASA’s Solar Dynamics Observatory. You can see the same sunspots in each image (ours is reversed because we were using a reflector). These images are from 12 November 2011. <\/span>
