However, the SOLIS 10830 filter is just sitting on a lab bench waiting for installation and could be fed a beam that would produce pretty good images of a large active region. (We have done this during testing of the filter). To date all we have done is hook up a 60 fps tv camera to look at the image on a tv monitor, but we could run the image into a video tape recorder along with time marks fairly easily. The bottom line: keep me informed about campaigns and we might be able to help out. Cheers, Jack Subject: Re: HIGH CADENCE IMAGING CAMPAIGN Date: Fri, 12 Apr 2002 11:58:32 -0700 (MST) From: Jack Harvey NSO To: canfield@mithra.physics.montana.edu Hi Dick, I thought some more about how to kludge up the helium filter. The folks in our imaging department have a digital video camcorder that accepts an external analog signal. This means that I can recod digital images at 60 frames per second for about 90 minutes. They also have editing software that will allow such data to be processed into nice sequences, etc. Evidently there is a time code on each frame as well so timing should not be an issue. This is in theory, of course. It has to be tried out in practice but should work. It's nice that we can benefit from the improvements in consumer electronics! Best regards, Jack
