AR's 2768, 2769, 2770 in High Res from 200mm | HA | Aug 5th 2020
Hey all,
With the stormy season here in Florida, sometimes I get decent seeing to attempt higher resolution and fine image scales. Today's seeing was good but not as good as the other day. I tried to extract what I could from the seeing conditions around 0.4"~0.5" arc-seconds when possible to look at our three cycle 25 AR's in high resolution at 0.3"/pixel from an 8 inch solar scope. I did some small scale images in HA & CaK of the three AR's for reference of position and the difference in resolution.
B&W:
Colored:
Seeing Conditions over 1 hour (very easy pattern to see it degrade over time rapidly):
Equipment:
C8 Edge HD SCT
+ Aries 214mm Tri-band D-ERF
+ Baader Red CCD-IR Block Filter (secondary D-ERF) + PST Etalon (HA) + 10mm BF + ASI290MM (HA)
+ Baader Red CCD-IR Block Filter (secondary D-ERF) + Baader 610nm + Baader ND3.0 + ASI290MM (Photosphere)
ED 80 Refractor
+ Solarmax II 60mm Etalon + PST Etalon + 10mm BF + ASI290MM (HA)
+ Lunt Cak B1200 + 2x Barlow + ASI290MM (CaK)
Very best,

Hi Marty,
Excellent images. I counted 9 tiny pores on AR 2770 ..

They're excellent Marty! I can see how you were fighting the seeing with the 8" shots though, I have the same experience! I seem to have very similar seeing constraints to you.

Thanks all,
The photosphere image of AR2770 ended up on SpaceWeather today instead of the pesky comet!
