Hi Utah-Astronomy, A few months ago, I finished building a Sol'Ex spectroheliograph (see www.astrosurf.com/solex/sol-ex-objective-en.html). I'm using the Sol'Ex, a William Optics Z61II, a ZWO ASI 1600mmPro and a Lacerta Hershel wedge to do narrow band imaging of the Sun. I finally set up a flickr account so I thought I'd forward a link to you of some of the images I was able to take yesterday. We finally got a break from the clouds so I was able to get images in hydrogen alpha (656 nm), hydrogen beta (486 nm), the Sodium (Na) doublet (589 nm) and the highest of the Magnesium (Mg) triplet (b1) (about 518.4 nm). It looks like the focus for the hydrogen alpha image wasn't as sharp as it was for the other images. If you'd like to take a look at the images, they are at: https://flic.kr/s/aHBqjA7oBS Clear skies, Dale.
