Departing Active Regions CaK Light 8th February

These active regions head towards the limb with a few small proms also visible.  60mm of aperture compared to 40mm seems key in resolving the spicules on the limb.  Conditions weren't great when this image was taken; low sun and high cloud, and so, as a result I look forward to putting this scope through it's paces in ideal conditions.  Taken at 960mm focal length with the homebrew CaK filter and the DMK31 camera.

Million Kilometer Filament CaK Shadow 8th February

The huge filament currently visible on the sun gives up it's appearance in caK light as it shadows the white plage of magnetic froth beneath it.  Spicules are much easier to see in this shot that was taken with the ED80 stopped down to 60mm, with the beloptik tri band, homebrew Cak filter and DMK31 at 960mm focal length.

AR12282 CaK 8th February

A new active region coming around the limb - looks to be a large spot, but not much plage - maybe it is decaying?  Taken with the Ed80 stopped down to 60mm, Beloptik tri-band ERF, homebrew CaK filter at 960mm focal length with the DMK31 camera.

CaK Full Disk 8th February

Conditions weren't great for this image, the seeing was all over the place and softened things up a bit, however the shadow of the million km filament can be seen hiding the white magnetic froth typified of CaK images.  Taken with the 40mm at 560mm focal length with the homebrew CaK filter and DMK31 camera.

Turbulent Sun - 8th February

This departing active region looked really turbulent and choppy as it headed towards the western limb of our star.  Taken with the DS quark on the ED80 with the DMK31 camera and 0.5x reducer.

Eastern Swathe in Ha - 8th february

Despite high cloud trying to spoil things I still managed to get enough half decent frames to put together this mosaic of the features on the suns eastern limb.  Taken with the DSQ on ED80 with a DMK31 and 0.5x reducer on the cameras nosepiece.

Million Kilometer Filament - 8th February

The largest filament for some time is currently visible on the face of the sun, spanning over  a million kilometers in length.  This image was taken with the double stacked quark and my new skywatcher ed80 refractor - this seems to be a really good combination, the camera was the DMK31 with a 0.5x reducer on the nosepiece.
