Telescope 150mm with Baader D-ERF, extensions, Quark chromosphere, 0.5x reducer and ASI 174 MM.
No newton rings to see (no tilter or eliminator used).

This is the first time that I have a recording all in one time.
The post processing from the surface and prominence is from the same recording.

At the first sight, all was oké.
The gray scale image is I think well, except the white ring around the edge (I don't know where this come from) ?
The color version is total different from my previous method, when I had two recordings (one surf. and one prom.), however with the same color settings. Hmm stranges results … but oké.

I do believe that my Quark is a good one anyway. smile.gif

Very nice Maurits waytogo.gif

 

So how does one capture the surface and prominence in the same video?

Nice Maurits!  I'm guessing that bright rim is simply parasitic light from the photosphere that one gets when using a bandpass as in a single stacked set up.  I'm sure Bob can explain it better, but I know with my single stacked Lunt I get this and have to play with the image to minimize it when capturing the surface and proms in one shot.  My luck with capturing all in one shot depends upon the brightness of the prom and how good the seeing is.  Then for me it’s simply balancing the Gain, Gamma and exposure to be able to get the two elements to show well.  If the proms are bright it’s much easier to accomplish.

James, with Imppg you can play with the curves and save the image first for the Proms , reset the curve and adjust it and save for the surface.

In Photoshop you can mix the two images as one.

I have the above images again reprocessed.
I have attempted to improve the white border.

Marty, this is the same prom as before (images above), but I tweak out more details in Imppg.
