Sun through fog, 20 September

Waiting for days to get this one at just the right point between obscurity and saturating the sensor. Astrostakert pixellated it, but Registax did a decent job of stacking. I might prefer the single image at bottom, which has had a histogram stretch, nothing more.

It does look a bit foggy   Similar story here when I woke up and for a change the fog was actually outside.

The fog seems to give the second disk an eerie feel. I like it.

In the true spirit of SGL I've had another go. Manually stacked 25 frames giving the best 10 or so 1.4 times the transparency they should have to effectively double them up (e.g. frame 10 gets 14% instead of 10%) and letting the best handful have twice their allocation. Then unsharp mask as it's too big for Astra.

Then I did a local EQ on the best frame - this emphasised both the spots and the bits around them (faculae?) and added this at 6% transparency which added a little more contrast and gave some texture to everything.

Main benefit is the very small spot near centre, invisible in the automatic stack but clear in most frames, now shows quite well.

Well caught. Rain clouds here, mainly

The new stack is a definite improvement.  Worth the persistence

The last image is very good well done for sticking at it.

I think a sheet of solar filter will be in order. I hope it's not a slippery slope, I've already googled 'PST'...
