M4 - Global Cluster in Scorpius

This is one of our favourite clusters unusual because of the very few blue stars within the cluster. Explanation " M4 may well be the nearest globular cluster to the sun. Interstellar absorption in this direction is estimated at 1.4 magnitudes and accounts for the yellow-orange colour " ( Daniel Verschatse )

NGC 6067 - Open Cluster in Norma

This cluster can be found in the rich dense part of the Milky Way.

Hi Barb and David, These are two very lovely images. The star colours are wonderful and give the images a lift not often seen. Worth spending a bit of time looking at.

Lovely images and very nicely processed.
Well done.

Excellent work on these two clusters Barb and David. You've maintained the star colours nicely. I'm not certain if M4 is showing its full extension, but the result is certainly pleasing. Thanks for sharing these as clusters often don't get the stage light compared to other extended objects. Well done.

Great GCs. I love the way they shimmer.

Thanks Trevor - hope you get some decent skies soon



We enjoy imaging clusters Alan. We usually do them when we have to spend some time waiting for our chosen object comes into imaging position.



Like to try and get the star colours right Doug particularly on clusters as the subtle star colour differences are important. Thanks for the nice comments.



Appreciate your comments Dennis - Thanks



As mentioned above Jase we usually image our clusters early in the night while we are waiting for our chosen object to come into our imaging field



Glad you like the achieved result Frank
