The famous double cluster in Perseus was known in antique times (probably even pre-historically), and first cataloged by the Greek astronomer Hipparcos.

Both clusters are situated in the Perseus OB 1 association, and also only a few hundred light-years appart, at a distance of over 7000 light years. They are both quite young: h is listed at 5.6, chi at 3.2 million years (Sky Catalog 2000); their hottest main sequence stars are of spectral type B0. They are approaching us at 22 (h) and 21 (chi) km/sec, respectively.

Excellent image. So much so, I have reprocessed the images I submitted previously (Adobe Photoshop CS) to try to bring out the additional stars that I can see in this image.

Cheers for now.

Afterburn how did you process the image? The reason why I ask is that the contrast and colour are very good, much better than you'd usually get off an unprocessed image.

A 2 minute long film shot of the Double Cluster that I took from the summit of Spruck Knob, West Virginia, with an Orion ShortTube 80 achromat can be seen at http://www.skyinsight.net/forum/modules.ph...=view_photo.php

Matthew,
If memory serves (and a lot of times it doesn’t) this is a single image and all I did to it was a slight adjustment t the curves to darken it then I ran it through Neat Image software to remove noise. Here is a piece of the original, unedited image. As you can see there is not a whole lot of deference. Out of all the forums that have pictures that I have been to I think I’m the only one using the New Olympus C-8080. Everyone else is using Nikon, Cannon… That may or may not have something to do with it. :unsure:

this is my best Perseid double cluster photo. Our ccd doesn't give a wide view



I know, it's only a single cluster. I have got to figure a way to take wider shots.
