Cak Sun 10th April

Post by marktownley »

Got lucky with the weather this morning, after a day and evening yesterday of drizzle, grey skies and rain I found myself sat in a band of clear(ish) blue skies, to the south of me was yesterdays weather, to the north of me was overcast and snowing. Was white over at my parents house 40 miles to the north...

The seeing is normally better than would expect in these conditions locally for me, and so decided to shoot some CaK. First off the full disk 60mm f16 and was pleased to see the chromospheric fringe and also ghostly proms dotted around the limb. Worth a double click for an explore...

Seeing wasn't as good as the other day, but I thought i'd chance a close up in 100mm at ~f40, 8000 frame avis with the IMX174 and 150Gb later and I had a couple of usable images. First of all the plage in the northern hemisphere:

Next up a region closer to the eastern limb looked to be crackling a bit, with quite a few bright points. Pores seem to have been coming and going here all morning, so fingers crossed it may develop into something more...

All the time I was imaging the blue sky gap was closing down on me, and while I would have liked to have shot more, this is all I could get, as I type now the sky is completely clouded and precipitation looks imminent. Hoping to get another look tomorrow fingers crossed!

Hope you like!

Mark

A cracking set of images, Mark. I got lucky with the weather this morning as well; sunny and dry for imaging and painting some garden features. It's cloudy and raining now. It just goes to show, you've got to collect data whilst you can.

You're getting great prom and limb spicule definition with your setup. I cannot see anything unless I use just a Baader K-Line and even then the images are somewhat 'thin', with low contrast.

It's good to see you managed to get some data before the clouds rolled in Mark, great imaging.
