Ha Full Disk 23rd February

The seeing was not great for the SM90 today - the spicule ring was just a featureless ring rather than the dancing forest of pampas grass it can be when conditions are good.  Still, despite the sun being devoid of the usual prominences there was a nice filament and region of plage approaching the limb.  Taken at 800mm focal length with the Grasshopper 3 ICX818 camera.
