AR12796 in Ha - 16th January

ar12796-colour There was just enough time to run off just over 1000 frames for this image before the cloud rolled in. I did manage to get the filter tuned properly, but wasn't enough time to get rid of the dust bunnies off the chip. The new active region looks nice as do the filaments.

CaK Full Disk 31st December 2020

CaK-FD-colour December has been a productive month for me solar wise, no doubt helped by clear skies at the weekends, but also by the concrete observing pad constructed during lock down in May which gives me a view of the afternoon sunshine in winter time. It's nice as we come to the end of the year solar cycle 25 is firmly active in the suns southern hemisphere. I used the Coronado 40mm f10 scope with a 2x Cemax barlow along with the FLIR GH3 91S6M camera for this full disk.

Filaments and Prominences 31st December 2020

filaments-colour proms-colour Todays sun looked great in the eyepiece earlier with the most dramatic feature being the prominences and filaments. Both are the same feature and are clouds of cool plasma held aloft by magnetic fields.

CaK Views 27th December

CaK-FD-colour CaK-Close-colour Seeing is never going to be on side with the low winter sun at this time of year, but the 40mm Coronado scope showed itself to be a great performer at these shorter wavelengths, reveling all the large scale activity in the suns southern hemisphere at the moment.
