AR11234 @ 705nm TiO Wavelength

This saturday morning afforded a few hours of sunshine before the clouds and showers that are associated with the unsettled airmass that currently resides over the UK. After a week when the sun was putting on some real fireworks todays disk was relatively blank at visible wavelengths, with AR11234 being the most prominent feature. This was taken with the 127mm frac @ f19, Lunt wedge, 705nm TiO filter and DMK31 camera. Realistically this was too long a focal length to be using as the image isn't as sharp as I would like or know is possible. Good old British seeing conditions!
