Omega CaK stack

Post by Merlin66 »

The weather hasn't allowed me to test the Omega stack....
It's the <390nm UV block as a "mini erf", then the 80nm CaK followed by the 2A CaK.
Mounted on the TS102, Baader Herschel wedge (with 1.6ND filter).
Using the ASI 174MM.
(I've had to remove the tilter to gain focus...)
Well, today has thin high cloud, little wind, today's the day.....
Just collecting some AVI but visual on the screen looks promising. :cool:
Stay tuned!!!

Looking good Ken! Reading the setup (wedge and ND1.6) it sounds like you have a lot of light coming through (which isn't a bad thing!) - what sort of exposure are you at?

I have found this program is very useful for choosing RGB values:
