Thanks, Chris, very cool (or should I say Hot!) imagery of the sun. 

I was curious about the performance of the 5x Barlow and it sure seems to do 
the job. I wanted to use something that would give me a little more oomph when 
examining the moon, planets, or close double stars. We've been having some good 
seeing that would seem to tolerate a good amount of magnification. 

Are you doing eyepiece projection to get the images and what is the resulting 
f/ratio? You must have to increase your exposure time quite a bit when going 
from x2 to x5 Barlow to get a good exposure. How quickly in succession do you 
have to take the images before the granulation or prominences change their 
position? Thanks!

Clear skies, 
Wayne (aka Mr. Galaxy)

The solar granulation was easy to see this morning around 9:30am, so I set up 
the solar scope again to image the details. And what details there 
were!&#65533; Lots of filaments, sunspots and gorgeous prominences.&#65533; I 
also wanted to try out the new Registax 6, which is so much more powerful than 
all previous versions in that it can register the entire solar disk - even on 
the granulation perfectly.&#65533; Youll see the difference in these images:

Thanks again for looking.&#65533;
