Had to start imaging at 1.30 am on two nights to get this by the time it rose above the house getting to bed after 4.30 am.   :!

A lot of cloud spoiled the subs on the 2nd night when I got the colour.

Really good Carole
I like the stars!

Thank you Noel.  When you say you like the stars, do you mean the RGB?

Carole

The Thing

That's a superb result Carole. Love the colours.

Carole

Thanks Duncan, really glad to have discovered this lens.  I will probably crop the top out at some point, but wanted to show the full frame for star shape in corners feedback.

Yes exactly; I like the colours but looking at the Ha - the stars are nearly perfect right out to the corners, which is really good.  Just goes to show what your lens is doing.

Thanks Noel, I have started trying to add RGB stars now to narrowband images, though it has taken me a while to find a decent way to process this.

That's a great result Carole!  You should be well pleased.

Carole

Thanks Mark, yes I am really pleased with this lens after years of saying I am rubbish with camera lens imaging.

In this instance it wasn't a case of the workman blaming his tools, it was the imager blaming herself when it was the tools that were at fault.  Lol.
