Saturday 8th February Sunshine and Polar faculae, help needed!

Post by Montana » Sat Feb 08, 2020 6:51 pm

Hello,
This morning was beautiful clear blue sky and I set up the TEC140 in my new observatory. Oh how I wish I could use it all year, it is so nice, out of the wind, comfortable and to close the window at the end of the session is marvellous. You can pack up whenever you wish :)

Anyway, I set about taking 3 full discs and searching for polar faculae to prove they are visible throughout the photosphere and chromosphere. The most polar faculae were located in the north today and so I overlaid them in Photoshop. It is a nightmare to get aligned correctly as the camera is in a slightly different place each time. However it is great in Photoshop layers and you can use the slider to fade in and out to see the comparisons of bright points between the layers. I have some screen shots but how do I present them? is there a way of animating this in Photoshop or somehow? I don't know. Has anyone got any clever ideas?

Hi Alexandra,

Great set of images.
is there a way of animating this in Photoshop or somehow?
There is a way to make a animated GIF with Photoshop but please do not ask me how to :lol:

I dig it! Great efforts and wonderful discs!

As for making an animation, you can do it with photoshop and layers, and just crop it down to show the area you want in the FOV, then set each frame in the animation to last x seconds and you can add fade transitions, etc.

Alexandra,

Awesome images! Those polar faculae are difficult to pick up visually but I have succeeded on occasion

Nicely done, Alexandra. Tricky to image.

Interesting to see these features develop as cycle 25 continues to make its stuttering start.

I use Photoshop CS2 to align (using difference) and crop the images together to make them the same size, then save each layer as image 1,2,3 into a new folder. Then use 'Image Ready' to "Import Folder as Frames", then change frame delay to 0.5 sec or so and "save optimized as..." to a gif file. I think Image Ready (an Adobe thing) was incorporated into Photoshop years ago, I am still using CS2 and it was a separate thing, but it works. (deleted distracting gifs!)

Thanks guys, I knew it had to be in Photoshop somewhere. I knew how to do the original animations with lots of frames but had a mental block on how to do it with just 3. Thanks to you guys and Apollo I realised I had to make a series of fading frames and then add them together in the animations tool. So here is the finished product.

Somehow overlooked this one.

Nice work capturing the faculae. Great looking animation as well.

Shows the photosphere and chromosphere limb really well, unusual to see this so clearly
