I merged two stacked photos for this. One of the disk the other of the prominences. I'm not completely satisfied with the result but I think I'm getting closer. C&C is always appreciated.

I love it. The red gradient background is a little distracting. Try smoothing it out. Not sure if I asked before, but what lens and camera are you using? Is this something I could shoot with a Canon dSLR and 400mm telephoto lens (adapter needed of course)?


I'm in Canada. Isn't that weird!

Thanks. The background is red but the gradient is an artifact of the stacking process. I haven't figured out how correct it...yet. I'm using a ZWO ASI120mm-s video camera on a Lunt 60mm Ha telescope. This telescope only shows a thin band of the hydrogen alpha spectrum which allows me to see surface features and limb prominences. A set up like you're describing will work but the solar filter you'd need would only allow you to see and photograph in what's called 'white light'. Some surface features, especially sun spots, are nicely visible. Others, such as prominences, are not.
