I don't know what this interesting feature is called, but at 12 o'clock inside limb was an "Eiffel Tower-like" spike emanating, along with a nice prominence at about 1 o'clock. Still getting the hang of processing. Just a single iteration through "high pass." Sharp Cap "free" doesn't seem to have the calibration frame for subtracting garbage. I lucked out and had little. Thanks for looking.

The "Eiffel Tower" at this scale just looks like an interesting arrangement of spicules.  If you extend it a little it looks like it has a head and 2 eyes looking to the left maybe some arms too?

Nice one. Have you checked out Marty's processing tutorial? The new one. If you haven't, give it a look.

I was watching that one today with my 80mm loaded with the Quark "P".

Thanks for your comments and "likes"

 

The resolution I'm working at, I think, doesn't lend itself well to multiple "high pass" iterations. But, I am using techniques Marty describes. And the camera is slightly different from the characteristics from what I see others using. But, I am going to try boosting magnification, incorporate something in the imaging train. I'm just not clear on which method.

 

The blocking filter has a threaded nose piece that slides into the helical focuser. I was wondering if I could thread onto the nose piece, a Uranoport Piggy Back barlow between the etalon and blocking filter? The barlow is 1.5x, small...wouldn't add much weight. Just not sure. 

 

I have a 1.25 inch, 2.5x Powermate, too. Seems like over-kill. I can only place it in front of the camera behind the blocking filter. And, it is weighty. Right now, the camera is on a spacer that is on the blocking filter...threaded.

 

Thanks ahead for the help,

 

Paul

I think the sharpness you show here is OK for the setup and the seeing.  You don't want to go too far and start getting artifacts that you might think are real structures.
