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 Sky90 array image, 5 hours of 30-minute subs.

A slightly better Arcturus reprocess.

Arcturus is the brightest star in the Northern Hemisphere.

A Noel Carboni reprocess of old Sky 90 array data using AstroFlat.

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.

 

A rather oddly-framed 4-framer using the Sky 90 array of the Merak region.

Sometimes it is good when someone else has a look at one of your images as they can immediately point out stuff which you miss (because you’ve been looking at the thing too long).

Bud Guinn immediately saw some errors with the 2-frame 200mm lens Double Cluster panorama which I hope I have rectified in the version below.

Here we have 2-framers of the Cocoon nebula region and the Double Cluster region.

Hopefully these are the last two images I need to reprocess from the 200mm lenses.
