AR's 2770 (Light Bridge!), 2769, 2768 in High Res HA | Full Discs HA, CaK, WL | Aug 9th 2020

[MalVeauX]

Hey all,

The sky was relatively clear this morning so I was able to take a look at AR's 2770 with its spot & light bridge, 2769 with its filament and 2768 as it rounds the limb with lots of mottling still. I managed to get some high res data with the 200mm with pretty good seeing. Clouds rolled in fast, so sadly the rest is courser scale and I was slightly off focus for the photosphere image of 2770's spot and cells. Managed some discs in HA, CaK & WL (610nm) with a smaller 80mm refractor for comparison.

Holy moley!

In many ways adding colour to the Ha ones seems to make them less dramatic.

I need to try harder! Perhaps a move to Florida might help. Our skies have been very uncooperative this last 6 weeks.......

Incredible image quality! Unbelievable seeing conditions!

You are really making the most of your 200mm aperture!
