Foggy Friday 27th March

[marktownley]

Woke on friday morning to low cloud / fog, which hung around for a couple of hours before partially burning off, unlike previous days there was a distinct milky haze to the sky, which made itself apparent as variable transparency - the histogram in firecapture was going up and down, and also an increase in exposure time at CaK wavelengths. As per all week the seeing was awful so I stuck to smaller apertures.

First off the full disk, and it is pretty blank! there are a few small filaments in polar regions, and a few brighter points around the disk but that is it, there was a prom visible but I struggled to get an image of it. As usual taken with the travelling scope.

Moving onto CaK and the ED80 (stopped down to 60mm) is rapidly becoming my favourite scope for CaK. First off the FD.

Then switching to the IMX174 chipped camera and the 3x barlow for a closer look at different bit of sun...

Absolute minimal processing on these CaK images, they pretty much are straight off the camera. Looks like today is cloudy, and for the foreseeable too, so any more images are going to be quick snaps in between the clouds.

Take care.

A featureless disc however fine images, as usual. Based on meteo maps you will enjoy the anticyclone for a few more days.

Hi Mark, very good images!

True solar minimum right there indeed.

Nice set of images nonetheless Mark.

These are beautiful Mark, thank you for the views we didn't have any fog here thankfully but I really did need to catch up with work.

Great results, Mark. I like that you can see the spicule layer in CaK.

Lovely images Mark.

The master of processing understatement provides plenty of subtle clues to underlying solar activity in his fine images.

Great images there Mark, very uniform disks

[MapleRidge]

Top quality images Mark...the full disks are very even and longer focal lengths do show more details.

Excellent work
