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

Post by MalVeauX » Thu Oct 10, 2019 5:46 pm

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.

That's a great set Marty! I like the 80/150 comparison, the jet transit is cool too!

Hi Marty,

Like them all, especially the plane transit.

That was one lucky jet transit, a transit of the prom! anywhere else and you would never have known :hamster:

I like the 50:50 shot too :bow

Spectacular high res shots, Marty. Interesting comparison image and the plane transit at that magnification, Wow.

A very fine set of images, Marty. Beautifully imaged prom.

Cool plane transit too :)

Thanks all, :bow

That big prom is gone now apparently, now that I have another day off. Sigh!
