The active region AR1654 in Calcium-K wavelength on 11 Jan 2013 - The active region continues to develop and we have nice weather (although poor seeing) to go with it.

The active region in CaK on 16 Jan 2013. Setting things up earlier resulted in much better seeing. The setup is identical to the first post.

The active region in H-alpha on 16 Jan 2013, taken with a similar setup to the CaK image but with the Lunt CaK module replaced by the LS100T H-alpha filter. The raw videos were terrible but the final results are surprisingly acceptable after stacking.
