Hi All
Got home after work and sun was shining yesterday so I grabbed a few avis. Seeing was reasonable for 5pm but variable. Got better air for the proms and had to push the surface a little in processing. Not that happy with the rim merge with over feathering but its good enough for a post as its getting late here. Hope you enjoy. The usual LS80 +DMK41 & 2.5X powermate.

I like it a lot, is it a merge or just a unique video image?
Re: Surface & Proms 13th Mar - After Work 5pm Fix
HI Ted, great stuff! The way I merge the disk to proms is to select the black sky with the color range command, invert and then smooth selection 25 pixels. Then I contract 2 pixels, feather 2 pixels.
One thing you might want to keep in mind is that the rim of the sun is covered with a 2000km layer of spicules and you shoould try to keep them along the edge if possible.

Thanks. yes it is a merge and I tend to call it a composite.

Thanks Chris. Agree, Yes I have used this and other methods for selection with varying degrees of success. I'll try your formula combination. I have not found one formula but then again I am somewhat chaotic in my processing. Sometimes I just sacrifice the spicules to get the proms and surface looking best.
I think there are several things happening with my processing at the moment, the level of seeing/mag varies considerably between avis and therefore how hard I process each composite seperately. This causes causes differing artifacts in each frame. I am also trying differing settings and combinations depending if it is prom or surface data.
With me... sometimes my processing is "like a box of chocolates, you never know what you are going to get until you open it"

This is incredible! I've never seen such a good merge, looks like flames erupting. Beautiful work, well done
