AR2740 & Limb | HA | May 5th 2019

Post by MalVeauX »

Good morning all,

I'm off a few days, so I just knew the weather would be awful. To my surprise yesterday I had some sky time. This morning, the storms are here. There's lots of clouds and raining here and there. A big lightning storm just rolled through. I set up regardless and cracked the top of my observatory, a little tenacious defiance against the odds, that I might get a sucker hole at the very least. I was only out from 9am to 9:30am because it was just too nasty. Literally raining. But sometimes a tiny sucker hole passes through, with just enough transparency to get something. It was enough for me to at least focus briefly, but not critically. I didn't even have time for flat calibration. I captured a single 500 frame sequence over and over as the clouds passed, and sometimes I had to close the top of my observatory for drizzling rain. For the briefest 3 seconds, I managed to capture some data. I figured it was rubbish because there's clouds passing through the sequence. But, I tried anyways. Registax couldn't stack it. AS!3 stacked it though! I processed out the gradients & rings and ended up with a workable piece of 3 seconds of stacked data. Lovely prominence this morning near AR2740! I had no other time of course, and the rain then came. So this is all I was able to do. A single image from a single 3 second sequence of capture of 500 frames. I closed up and ran into my house at this point. It's now 10am and my electricity is flickering on/off and it's raging raining and with a bad lightning storm over head.

A great image considering Marty. Sounds like you're getting a dose of UK weather down there.

You are very lucky to have an observatory so your set up and set down time is fast, which is very good for days like this, well done!! I wish I had one :)
