Our Sun showed some amazing proms today! The sunspot activity has dropped in the past week but the limb in h-alpha was very active. There was a very large bright prom at ~210-220* that looked like a piece of bright ribbon flipped over. Seeing and transparency were both good today.

 

I utilized the Tilting Sun graphic to show orientation, I shifted my sketch to mirror solar east/ west but inverted. Celestial east/west are also shown in the graphic.

 

This is black Artagain paper with white charcoal and pencils. The tooth of the black paper does well for showing chromospheric network on the surface.

Amazing! The texture is perfect and the detail in the proms is almost photographic. Hell...who needs a camera and all that expensive gear???

Thanks Dave appreciate the comment. I would really like to be able to image too, I have seen some amazing photos in the solar imaging forum. But for now I know my efforts are better placed in sketching

Cindy,

 

That is a very fine looking charcoal sketch on black Artagain paper with just the right tooth to give that fine texture to the Sun in H-alpha. A very busy solar limb.

Excellent.

 

Frank :)

Lovely.  Must have been painstaking with the values.  That's great to get that texture assist [assume that's what's meant by "tooth".  Learned a new term today smile.gif]  It really looks like the granulated solar "surface" seen in photos.  Well done!

Thanks Frank, Look at the Sky 101, and bphaneuf for the comments

 

Frank, its amazing how just a little blending can look so much different than the blending used for creating smooth maria on black paper. 

 

bphaneuf, the “tooth” is just the roughness of the paper, and it works great for creating this type of texture. Its actually pretty smooth paper but as I mentioned above it all depends on the blending level.

This is so good.  I love the texture of the solar disc and the perfect limb darkening!  This is amazing.

Cindy It looks Amazing like a monocromatic Photograph , Rendering that much detail must have taken a long time to replicate
I really like the granulated texture.
Thank you for your awesome contributions.
By the way I have the twin portaball 12 1/2" Zambuto on a Blandin platform Absolutely loveit,Greg makes a great lightweight platform.
Clear skies always Jon

Cindy,

 

Excellent H alpha sketch!  You've captured a real three dimensional look to the solar disk.  Nice work on the proms and filaments, too.  waytogo.gif

 

After seeing this sketch, I may stop banging my head trying to do Ha color sketches and go back to black and white.  grin.gif

Thanks for all the comments, Ian, Eric, Jon, Michael, Tom, & John, and thanks for the likes!

 

Eric, I had not done a solar sketch on the Artagain black paper for a while and forgot what a nice surface it has for showing solar granulation

 

Jon, the 12.5” Portaball is my all time favorite scope and especially on Gregg’s platform. I also can detach the ring and use it for my 8” Orion for star parties. Best thing I may have ever purchased and if I level it right, its spot on for the evening. Sounds like you enjoy yours as well? You have quite a nice array of equipment in your arsenal! 

 

Michael, coloration is something I love but struggle with. Using color on black paper especially for proms loses its brilliance and I am always experimenting. I am not good with photoshop at all but have tried my hand at some inverse colors which works well (blues become red) which is nice for processing but not for a keepsake sketch. 
 

Cindy
