Many thin clouds today and some wind, but there were short periods of good-enough transparency and good seeing. 

Here are the best shots of AR2871, with an enlargement of the active region12_48_28__pipp_lapl5_ap35497b_AR2871.jpg 1248_cropped2_AR2871.jpg

 

And here is AR2872.13_17_45__lapl4_ap37110b3_AR2872.jpg

 

All images with Takahashi TSA-120 with double-stacked Lunt 100 mm H-alpha filter.  2000 frames, stacking best 25% in Autostakkert, then sharpening in Registaxx.

AR 2872 is really nicely done. Right settings.  

 

IMHO, the scale can be easily be 50-70% larger.

Yes, you're right-  I cropped it the way I did because there were some bad Newton's rings that didn't come out with my flats. But you are certainly correct !
