AR2824 in High Res WL, HA, CaK | May 20th 2021

[MalVeauX]

Heya,

I nasty storm cell swept through last night, but usually I have decent seeing after storms, so I woke up and went outside to a fairly high temperature delta from night to morning with gusts of wind, but seeing turned out to be good, so I attempted some high res imaging with a 200mm and 150mm and then finished my session with a 120mm moderate resolution imaging of the AR2824 near the limb and total session time was around 40 minutes for tri-band and two image scale captures. AR2824 has a lot more going on than the previous spot that just left our view around the limb, with a great mottling area and plage and it's throwing active small flares, would be great to see some long animations as things are moving quite a bit. My weather only lasted an hour and now its cloudy and going to rain, but storms are good around here.

Sigh, may I just say, it's extremely difficult and annoying to embed images here now, since I cannot simply post a BBCode image from my hosting platform(s) and instead have to post a link to it, that then must be fetched by the forum software or it will not display anything and break, and the forum constantly makes it difficult to space images so they are not hugging or sharing the same line. This is frustrating to post more than 1 image frankly. I try to share a lot, but this is really just making it take way too long when it's a simple process on other systems.

Any advice for stream lined image posting (like being able to copy & past all my images in one go to allow this to be a faster process)? Or is this just how it is now?

Very best,

Perhaps post in the suggestions, bugs and foibles section and Grant will be able to advise if anything is possible.
