Ha Full Disk 10th January

A new year, a new solar image and a new scope mod.  I tried a Lunt 50C double stack filter in place of my usual SM40 etalon that is used to double stack the basic SM40 scope.  I was quite pleased with the result, seemingly giving a result that is centred closer to 656.28nm than my usual setup which seems slightly offset.  Given the boiling seeing with todays low sun I was quite pleased with the results.
