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.

Each image is a 2-frame wide-field mosaic.

Ruchbah and Caph – main stars in Cassiopeia.

Another reprocess – note the two Carbon stars to the left hand edge.

Noel Carboni’s new AstroFlat tool makes it very easy to bring lots of different datasets together (something that was a huge pain before the tool).

So this is the first image showing all 11.5 hours of 20-minute subs for IC2087 taken with the Canon 200mm lenses and Trius M26C OSC CCDs.

Aldebaran, the Hyades and NGC1647 (200mm lens 2-framer)

Tarazed and Barnard’s “E” (200mm lens single-framer)

And the last one for today is the 4-framer taken using the Canon 200mm lenses and Trius M26C OSC CCDs.

This is the whole of central Lyra.

Now going back looking at old data where I have put mosaics together (not very well).  Noel’s AstroFlat tool allows you to flatten each frame of the mosaic so that they are dead easy to stitch together seamlessly.

Below there is a 4-frame mosaic of the Kemmble’s Cascade region taken with the Sky 90 array.  Each frame is 2-hours of 10-minute subs.  I have applied the Akira Fujii effect to make the Cascade stand out.

Also below is a 3-frame Canon 200mm/M26C image on the North America/Pelican region.  I overlaid some higher resolution Sky 90 data for the NA/Pelican as the 200mm data on its own at 6 arc seconds per pixel is a little soft.

A Common Name for the IC1396 Nebula.

Why doesn’t this magnificent nebula have a “common name”?

What would you call it?
