I have very deep data of M13 and for the first time today I took a good look at the image to see if I could find “The Propeller”.

And there it was!!

I took this data a few years back.  It is a 4-frame mosaic of the Double Cluster/Stock 2 region in Perseus taken with the Sky 90s/M26Cs.  Each frame is 2-hours of 3-minute subs and North is to the right.  It is only with the recent availability of Noel Carboni’s AstroFlat plugin that I have finally been able to put this one together.

Noel Carboni put some old Canon 5D MkII (unmodified) data through his new AstroFlat plug-in.  I am amazed at the amount of “red” he has managed to pull out from an unmodified DSLR camera!!

A slightly better Arcturus reprocess.

Arcturus is the brightest star in the Northern Hemisphere.

Struve’s Lost Nebula, Burnham’s Nebula, Hind’s Variable Nebula, NGC 1555 – they are all the same object and it is in the centre of this image.

65 x 20-minute subs (almost 22 hours) went into this one using the Sky 90 array at the New Forest Observatory.
