Re: 47 Tucanae with 155EDF refractor

It was processed back in 2011. I have not gone back to the original subs.Too many other projects.

I did want to post this because the 155 is probably my favorite medium sized refractor and I don't use it much here because I have a 160 (which is unfortunately longer and heavier). The glass for the 155 ended up having more and more problems (glass made by Schott) so I finally threw in the towel and redesigned the lens to use all Ohara glass from Japan in our 160 EDF as well as all the other newer scopes.

Very beautiful Roland. Simply out of curiosity, is this the image processed in 2011 or did you use modern techniques to reprocess the 2011 subs?
