Pleiades

[cometcatcher]

The Pleiades, or in this shot, six of the Seven Sisters, given the angle and field of view of the 10 inch scope.

From Wiki "In astronomy, the Pleiades or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged, hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky.

The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years.

Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood."

Capture details: GSO 10" F4 Newtonian, Baader MPCC MKIII, 353 x 30 second subs, HEQ5 Pro unguided, Pentax K-5.

:thumbsup:Nice one

Nice image. Why are the diffraction spikes in dashes instead of continuous?

Greg.

Not exceptionally deep, but a pretty image Kevin.



My C300 narrow band spikes are dashed and my RGB ones are rainbow striped.

Nice. One would never think that magical misty stripy reflection nebulosity was there just looking with binoculars.

[Atmos]

Quite nice Kevin, another one of those objects that I am yet to image.

Thanks Graham!



Thanks Greg. The earlier processed versions have RGB bands in them (as Rick said) but the use of HLVG green plugin makes them look a bit gappy I think.



Thanks Rick! I think I'm pushing the limits of a non cooled DSLR in summer here. Temps tonight are 27C and that really puts a limit on how deep I can go. But the sky is clear so I'll be in the obs just the same. One day in the future I will have to bite the bullet and get a dedicated cooled CCD.



Thanks M&T. Dunno about Binos but I had a good view of the reflection nebula one clear cool night with a 10". The same night the horsehead was visible.



Thanks Colin. Will be looking forward to your image!
