I was quite excited by the Clear Sky Chart forecast: average seeing, average transparency and no clouds.

Reality was that the transparency was poor; that and the faintness of the proms made the capture and processing of these images quite a challenge.

 

Full Solar Disc (and the Coordinate system used)  [32mm + Quark + ASI178MM]

Love the floaters! I imagine you were capturing in 16 bits for these faint ones?....

Very best,

Yes, it was either sink or float today.  lol.gif

 

 

Nice images!

Yes, I image visual would not have shown much at all.

I use 16-bit capture for everything; it's a necessity when trying to bring out and sharpen faint proms... else they fall apart.

 

 

They were definitely faint today!

Yes, no feinting about that grin.gif; they were very faint.  I hate groveling in the noise... it's impossible for me to capture the surface and faint prom in one image capture.

 

Thanks for the comments,

 

Best,

Rick

Floating rake is pretty wild.  Some kind of serious partying going down on old El Sol.

Nice captures Rick!waytogo.gif

 

I see you're not imaging around the clock anymore. grin.gif

 

That rake looks more like Bullwinkle to me.  I wonder what that says about my mental health. crazyeyes.gif question.gif
