Hi All,
I popped out for about 1-hr on Wed night as I wanted to see if my new RGB filter wheel would focus ( I had to be up at 4.00am on Thurs so no long session planned..) - I pointed scope at Bubble since it is a relatively easy target to image & has nice colour & quickly captured approx 100 unguided 10 sec exposures for L & 50 X 10 each for RGB. Didn't really have any idea what I was doing. Found a great tutorial on web which explains LRGB using Photoshop & followed this through. Result is as shown: It was so much easier using filter wheel then taking camera in & out/ refocussing etc..

Image needs much longer exposures but I'm pleased it all seems to work.. I'll try this again when moon is not around. I added false diffraction spikes using astronomy tools..
Let me know what you think... Oh tuttorial is here:

Lovely image, John.
What a great little program, could do with all of Photoshop like that!

Thks Fay - The image has lots of room for improvement but at least I kinda know how to do LRGB now.. :-)
