Having seen Ken's and Terry's nice CaK proms last week I tried if I could capture some yesterday. I had to turn up exposure time to 10ms, and it took me some time to pull out the proms from the scattered light in processing, but I think they are visible.

Kind regards,

Hi Frank, thanks for the useful images and yes to turn-up the exposure-time a little and/or to adjust the brightness/contrast in the processing stage, does allow for the proms to appear. Also to make an identical image in Ha to compare the differences is useful.
Yours have come out very well...
I guess we will see more of the Cal-K+proms in the future...
Unable to try again today, but hopefully tomorrow.
Thanks for sharing
Regards
Terry

WoW, impressive. Looks really good!! It makes me think of a GONG CaK image if GONG worked in the CaK band.
