Saturdays CaK - 27th April


Recommended Posts

Despite April showers, in the dry gaps between the sky was about as blue as it ever gets here in the UK - fantastic transparency, and so decided it was worth a bit of CaK imaging. Once i'd got setup the view on the laptop screen showed seeing going from pretty bad to pretty good, so optimistically as ever knew if I kept the stack size small and the avi size large there was going to be some good data in there wink.png

Starting off with the full disk, this is a 6 pane mosaic taken with the 100mm scope running at ~f5 (I think!), usual CaK filter and DMK31 camera.

I decided to up the focal length, still with the 100mm up to 1600mm, and see what was happening at the smaller scale.

At the time this spot on the limb was assigned s2377

The area around AR11730 was looking good so did a 2 pane widescreen mosaic...

Needless to say AR11731 was always going to be of interest cool.png

Ever the optimist I upped the focal length to 2 metres for a little closer look, seeing was starting to play up with things, but this is passable:

Then the showers returned, and by the time they had gone was far too late for considering hi-res CaK, still, had a alot of fun taking these. Hope you like!

Thanks everyone for the kind comments :)

I'm so jealous of those close ups.

You have all the right bits Alexandra, you just haven't assembled them in the right order yet ;)
