Solar-on-sea, 11th October 2020

I was away for the weekend down on the South coast not far from Folkestone, with a very nice decking area facing the sea. Whilst there was patchy cloud around today, I still managed to grab an hour or so on and off observing the Sun during the clear spells.

I was using my trusty Tak FC100DC on a Scopetech Zero Mount and Gitzo tripod which makes an excellent grab and go setup. I use a Baader Coolwedge, with Mark IV binoviewers, and 25mm Zeiss Orthos which are converted microscope eyepieces and very sharp. To get to higher powers I use a x1.7 GPC and an AP Barcon so today I was at around x100 (on better days I often go up to x200). Finally a Baader Continuum filter helps to bring out the detail, particularly granulation and faculae.

The seeing seemed pretty good; granulation was immediately obvious across most of the disk and, given the current quietness of the Sun, I was pleasantly surprised to see some activity quite central in the lower part of the disk. It was quite fine, no large spots but two groups, one very compact and the other quite complex with a series of tiny spots and pores. There wasn’t much in the way of faculae visible today but still, good to get out there in such a lovely place to observe. Photos to show the setup I was using and the active area which is identified as AR2775. I couldn’t see anything at the position of AR2774. As normal, the views were sharper and with more detail than shown in the image.
