IMO open clusters are the hardest to process and obtain an appealing result without adding diffraction spikes, any help here with a step by step guide would be appreciated

Discovered by Lacaille 1752. The considerable southern open cluster NGC 3532 is one of the Southern Sky's finest Jewels. NGC 3532 was discovered by Abbe Lacaille on January 25, 1752 from South Africa, and cataloged as Lacaille II.7.
NGC 3532 got it's nickname "The Wishing Well Cluster" because the twinkling stars in this Open Cluster resemble silver coins shimmering at the bottom of a Wishing Well.
Nice photo, Trevor, but maybe clipped at the black end with the sky background pretty dark as has been mentioned. My visual memory of that bright star on the edge of the cluster is that it's distinctly orange. Maybe a little more saturation in the star colours?
I hadn't ever heard of the "wishing well" name for NGC3532. A quick web search shows it was made up by amateur Ray Palmer in 2006 as a personal whim to popularise the cluster. http://www.ngc3532.com/idea.htm

Surprisingly all main stream web sites with data about NGC3532 now refer too it a the Wishing Well Cluster. Yes it is a orange star but had too much halo so and too remove this I had to take some color out, I put it back maybe a bit much now
Thanks Roger I just had a look at your version and it appears some of what I processed out of the orignal thinking it was noise may not have been. Hard to get right sometimes without referring to what others have captured
