Erupting solar prominence animation

Recommended Posts

I pointed my solar telescope at a small prominence in the hope that it would do something whilst I imaged it.  Because I am new to solar imaging I don't know whether this is particularly lucky, or if it's something that's easily caught.  Over the space of about an hour I captured 18 videos, each of 1000 frames, using a mono DMK21.  I stacked 10% of the frames, and then manually went about aligning and cropping the 18 stacked images because ImPPG didn't like to do it for me.  I also took an image of the solar surface, just to get rid of the white in the image, and add something visually interesting to the solar disc.  I used a curves adjustment to make it orange, and then made a movie in MS Movie Maker.

 

Hope you enjoy it!

Well done, particularly with not a lot going on ATM.

Thanks Dave, I'm actually warming to this solar imaging carry on.

I have the Coronado SolarMax II scope which I haven't used in way too long. I am planning to do a timelapse of the sun in HAlpha one day too...

There have been some awesome prom lift offs over the years, leaping millions of kilometres into space.

If you root back a couple of years in this forum, when the Sun was more active, you should find some examples.

I was very much planning on selling this scope earlier this year but I convinced myself to give it another year!  However after a recent mini outreach session, it's clear that this type of visual observing is a huge hit with the general public, especially with the binoviewers.  For that reason alone I would keep it, but the imaging is great.

I think that selling should be the last resort... the gear is expensive new and selling generally get us peanuts... Personally I'd rather keep my astro gear that I might use eventually, such as my SMII.

Selling a solar scope would more certainly result in eventual disappointment and regret... at least for me.

Not a particularly rare event per se  but rarer at this point in the solar cycle and even rarer to catch one in the act.  ?

Good annimation.

 

Not saying I do it right but i tend to do shorter captures but more of them

 

200 frames every couple of mintues (or even 30 secs if its real active) stack 50 of the best then run it through PS annimation routine.

Cheers Steve. Thanks for this advice. I was just using an arbitrary amount. I did notice in some of the videos there was movement of the flare within the video itself. This created an issue when stacking. 

I suppose the million dollar Q is how do you know it’s going to be active :D

If you run the days movie on GONG you can see if any proms or ARs are performing.

If you're using Firecapture you can set it going taking a time lapse and leave it to it for an hour or so.

Thanks Dave - I did find that autocapture button you mentioned before, worked a treat :D

I do use Gong, and it did point me in the direction of recent erupting flares, so I just guestimated where to aim for.  I think that's half the fun.  I did image another small AR, and there was zero activity over an hour.

Same technique as I use then

      Hey all,
      I made an acquisition and processing tutorial a while back (3 years ago? Yikes!) and it is fairly dated in terms of what I'm doing these days. I've been asked for a long time to make a new one showing what I'm doing these days. Specifically how I'm processing a single shot image for both the surface and prominences and how to process them together to show prominences and the surface at once. I've abandoned doing split images and composites and strictly work from one image using layers. Acquisition does not use gamma at all anymore. Nothing terribly fancy, but it's not exactly intuitive so hopefully this new video will illustrate most of the fundamentals to get you started. Instead of an hour, this time it's only 18 minutes. It's real time from start to finish. I'm sorry for the long "waiting periods" where I'm just waiting for the software to finish its routine, it lasts 1.5 minutes and 30 seconds tops typically at first. The first 4 minutes is literally just stacking & alignment in AS!3. I typically will go faster than this, but wanted to slow down enough to try to talk through what I'm doing as I do it. Hopefully you can see each action on the screen. I may have made a few mistakes or said a few incorrect things or terms, forgive me for that, this is not my day job. I really hope it helps folk get more into processing as its not difficult or intimidating when you see a simple process with only a few things that are used. The key is good data to begin with and a good exposure value. Today's data came from a 100mm F10 achromatic refractor and an ASI290MM camera with an HA filter. I used FireCapture to acquire the data with a defocused flat frame. No gamma is used. I target anywhere from 65% to 72% histogram fill. That's it! The processing is fast and simple. I have a few presets that I use, but they are all defaults in Photoshop. A lot of the numbers I use for parameters are based on image scale, so keep that in mind, experiment with your own values. The only preset I use that is not a default is my coloring scheme. I color with levels in Photoshop, and my values are Red: 1.6, Green 0.8, Blue 0.2 (these are mid-point values).

      I first came across the term ‘Solargraphy’ on this forum and was directed to website dedicated to the art of Solargraphy.
      This is a basic photographic method of recording the path of the Sun as the year progresses. This image commenced on 22 June 2019, the day after the Summer Solstice when the Sun was at its highest altitude in the noon day sky and finished on 22 December 2019, the Winter Solstice when the Sun is at its lowest point at noon. The silhouette of the neighbouring properties can also be made out in the picture.
      Using a basic pinhole camera I was able to record every clear day the track of the Sun across the southern sky, each day  the Sun’s altitude was getting slightly lower.
      Whilst the camera is basic, the main challenge is to avoid water damage and as you can see from the image some rain has managed to find its way inside. However, the pinhole camera is cheap to make with the following purchases made via Amazon;
      100 cable ties £5.49
      20 35mm plastic film canisters £8.88
      100 sheets of Ilford Multigrade 4 glossy photographic paper £25.98
      The remaining items were already in the house (drill bit, tinfoil, electrical and duct tape).
      Given the potential for disaster I made two pinhole camera’s and one of them provided this image, the other was washed out due to rain water getting in. Making more than one camera certainly improves the chances of success. The camera's themselves were attached with cable ties to the down pipe of the guttering and facing South.
      Anyone wishing to learn more about Solargraphy and how to construct the pinhole camera should check out Tarja Trygg's website http://www.solargraphy.com/index.php .
