This is one I have a go at every few years. Being bright it doesn't take long so you can utilize the limited clear skies. I had some weird gradient stuff going on which I haven't worked out yet but hopefully I got rid of most of it.

Cheers

Steve

Thanks Colin. That's no doubt true. It's usually only the brighter stars that show colour.

Thanks Mike. It was the first shot after my latest mirror cleaning so I must have got that right.

How did you do that? Insitu or in a sink?

In situ - I use that first contact polymer film stuff and if you are careful by covering up sensitive areas you can spray it on leaving the mirror in place.

Aaaah I see, so that stuff really works then? I guess with an exposed RC style tube that would be quite handy...my closed tube Newt not so easy, would have to remove the mirror cell at least.

That looks great Steve, the colours really show the nice reddish hue as well as blue straggler stars all over the place. Top image

Good colour Steve and the resolution at the core is very tight. I take it this was with the AOX?

Yes I think it's good stuff and have used it a number of times over the last few years. I reckon it's definitely postponed the need for re-coating. Certainly it's more difficult with a closed tube. With the 12.5" RCOS (closed tube) I had to take the mirror out and it can be a tricky process with RCOS scopes.

Loving your globular images Steve!

Apart from Omega Cen and 47 Tuc, must have a go at some others.

Cheers,

Justin.

Nice image Steve.

I'm not sure about the colour of the core.
This globular has a B-V colour index of 0.65 making it one of the whiter globulars around.

Regards

Steven
