Some nice weather today so grabbed some Ha with the Lunt Double Stack and some CaK with the Lunt CaK module in my Skywatcher ED80.
Happy how these turned out.
Love your cak. That's a ripper of a shot.
Be interested in the CAK module details, where you got it and how much. You halpha is a bit average. I'd loose the double stack for a while until conditions are right.
