After a couple of weeks of what seems like never ending cloud and grey the sky turned blue late this afternoon to reveal old yellow face. I was messing around with some different potential combinations rather than doing 'serious' imaging. Good job really - the sun is blank! There were a couple of really small filaments on the disk and pretty much no other activity. The proms were the best thing and even these were small scale. Taken with a Lunt50 etalon on the ED80/600 and using the APM 1.6x telecentric to give f19 at the quark etalon. Visually this works well, however imaging wise I was struggling with the lack of surface detail. It's all about experimenting!
