Finally getting the hang of CaK imaging. My old eyes do not see any purple sun through eyepiece, but my Canon SX150 does a reasonable job, once I get it in sharpest focus. I mount my Lunt B1200 CaK filter on a specially modified Eon 72 (had to get a machinist to ream out the interior of 2" drawtube to get Lunt to go in far enough to focus. I use a SkyWatcher Virtuoso mount for convenience and light weight; getting old and with Parkinson's, it is ideal. I tried a variety of exposures, found 1/15" at ISO 800 worked best. Used about 4-12X zoom with Canon, shooting through a TeleVue 32mm Plossl and eyepiece drawtube custom fitted to the Canon zoom lens. Carefully noted the exact focus position in each shot; found for my Eon 72, 6.6 is best focus. Here is activity for April 8th about 1 PM, best shot to date.
