Moromete,
Your latest crop of images have quite notable vignetting and field curvature. What kind of reducer are you using?




Glenn, it's not field curvature. Actually it's a special 3D effect I applied to the images! :mao:


Novel but that one is now used up :-)

Cool veil. I always love to see its image. If you could frame it with F/2.6, I may have a chance with F/6 + x.5 FR.

Thanks for showing the interesting targets and nice shots!

Not for the 'FAINT' of heart... new [Re: Puck Ja]
      #5997386 - 07/29/13 10:13 PM Attachment (27 downloads)

Below is a screen shot I took last night with a point-and-shoot camera of the image from my MallinCam VSS+/CPC 1100.

The object is sometimes called the "Diamond Ring" and consists of two extremely faint components - a 14th Magnitude Abell planetary nebula and a 16th magnitude PGC galaxy. A chance alignment places the galaxy right on the nebula - like the diamond on the band of a ring! The central star is also visible. For a size comparison, the nebula is roughly the size of the 'hole' in M 57.

This is hardly a 'good picture', but I was so amazed that I could even see this object that I wanted to share it.

Overall, not too shabby for a backyard 45 miles south of Chicago!

Don

What a difference in quality with the temp Delta between his and mine.
