High Res Proms, Spicules, Cells | Jet Flyby | Oct 10th 2019

Heya,

It's rained the past few days, lots of storms, a weird wet October so far here in Florida. But this morning was improved, had a clear sky this morning around 10am and pretty good seeing, so I was able to get some high resolution data of a few features, despite there being very little going on, there's a rather big and bright prominence group that seems to be a morphology similar to either a hedgerow or curtain. Despite that, I also took a look at spicules at the limb without any major features as this can be done any day with good enough seeing, and an interesting comparison of convection cells in g-band at 80mm and 150mm apertures to show the difference in resolution when imaging at near critical sampling level. While imaging, I accidently caught a jet transit at the big prominence this morning which is really cool.

Very nice images, and a nice catch with the aeroplane

Super set of images as always!

The comparison between the Convection Cell Resolution Comparison 80mm vs 150mm is fascinating.

Mindblowingly good

Wow, the jet transit is superb!
