AR's 2768, 2769, 2770 in High Res from 200mm | HA | Aug 5th 2020

Post by MalVeauX »

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.

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

Thanks all, :bow :bow

The photosphere image of AR2770 ended up on SpaceWeather today instead of the pesky comet! :lol:
