An otherwise clear night of very good seeing was hampered by high winds, so my imaging session was restricted to shorter exposures of 60 second subs. Initially I did a check on the Blaze Star (T CrB) using a Star diffraction grid to record some LRGB data for just 16 mins – no sign of any nova starting just yet, but these data should provide a useful comparison of diffraction spikes should the nova be observed as is expected in the coming weeks. I followed that with two further sequences of 60s subs on M11 and the M56 regions of sky with the diffraction grid also attached. All data were captured in NINA with a ZWO Asi533MM Pro camera attached to an Altair 60EDF doublet refractor fitted with a 0.8 x FR. Data were stacked and processed in Pixinsight and Adobe Photoshop 2024.
