Here is a full disk mosaic and a prominence animation from this afternoon (June 22, 2025).  The images link to my Astrobin page. I probably should have run the data through Topaz sharpening and De-Noising (but I didn't).

So question, so a Lint 40 double stack Ealon? But you are using a B500 or B600 blocking filter?

 

As I have the Lunt 40 and going to remove the Lunt 40 Ealon and put behind the Quark Chromo for a DS..

 

Thanks Christopher

My blocking filter on the Lunt 40 is a B1200.  I have a pair of tilt tunable etalons up front on the Lunt 40. I use a lunt 40mm etalon in a Raf camera adapter in conjunction with a Quark Chromosphere filter on my miscellaneous refractors.
