Here is a colorized, cropped result of stacking 178 images of a prominence from Nov 12, 2018, using an ASI174MM and a relay lens+optical wedge combination. The workflow wasn't optimized because this was my first attempt at using the camera on spectrohelioscope, which was recently installed at Stellafane. The instrument itself is running at about f/72 when you account for aperture stops in the current configuration.

For a sense of the field of view, this is what the GONG instrument at Mauna Loa was showing at about the same time. The prom is in the upper left, near the 10 o'clock position.

I expect me and my colleagues will get better at this!
