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.
Please note that “Screensavers” of my images are no longer available for purchase.
Today’s EPOD is M92 – the ovelooked globular cluster in Hercules.
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!!
You will see in the images below that I have been beta-testing Noel Carboni’s new flattening tool for deep-sky images.
This plug-in makes flattening even the most difficult image data a doddle (even I can get good results).
If you carry out deep-sky image processing, then you must have this tool in your digital darkroom toolbox – it’s sharp!

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.
