Getting there Dave! I like the processing of the proms. I didn't spot the lower one in your image when I captured mine yesterday.
Looks to me like you have a little bit of uneven brightness. There's a hot spot just and right of centre (like you had a spot light shining on a ball from above and behind your right shoulder. I think that is just a matter of tuning the Ha filter to get a even brightness. That's help when it comes to mosaics.
Your images also look to me like you are just slightly overexposing and losing the highlight detail on the disk. Do you use the histogram to set your exposure? I set mine so the white point on the histogram is about 225 say. Always have zero intensity at the RHS of the histogram.

no Al i have just been doing it by eye where is the histogram in the image source software? i suppose i did deliberately line up the hotspot to try and make a pseudo 3d effect. hey how about when you doing some sunnage today you get a screen grab of your settings and such so i can compare to what i did?
yes i use the y800 and the gain was around the 300 odd mark - maybe the exposure was 1/125 or something similar?
With the SM40, my exposures varied from 1/54s low in the sky in winter with inactive sun to 1/90s higher in the sky and more active sun. I can't exactly remember my exposure with the LS60F but I think it was about 1/180s at 600mm FL. Bummer... no clues in metadata, I just checked.

thanks what i found with my videos. the only thing really recorded was the time and date i started the vid and that was in the name of the file.
