April 14 Evolution ...
A serious evolution between today and yesterday, with a beautiful "arch" forming on this prominence.

Re: April 14 Evolution ...
Very good images with much details in the spicule carpet, my Quark Chromo is not so good. Is the interference eliminator needed with the 174 ?

Re: April 14 Evolution ...
Wow!! this is a gorgeous shot
That is one thing I should learn, how to get an Earth on a picture. The biggest downfall for me is that I have never found a decent Earth picture to use and how you get it so small without it being one big pixel?

Re: April 14 Evolution ...
Hi Alexandra,
I think this Earth may be reasonably easy to use. I already isolated the Earth, its 673 pixels. I could explain it to you, but I have plans to make a Solar SSM ! I could publish it another time on the tutorials section.
There is some information on Brierley Hill solar blog, although I found the sound very hard to hear and understand.
https://brierleyhillsolar.blogspot.com/ ... rials.html
I had to learn Photoshop, layers and everything. Still not learned it al! after more than 2 years ! You can also use GIMP or Affinity Photo, which are less expensive alternatives and quite adequate.
I only found it after an extensive search online.

Alexandra, I have the "TIF image" that I use in my images as above.
You can use them, can I set it up here as a TIF file?

Re: April 14 Evolution ...
Hi all,
I think I have found an easier way to calculate the size of the earth (in pixels) - this will be an option in your imaging program - to resize the earth image. Assuming the diameter of the earth is 109 times smaller than the sun, and the sun is about 30 minutes of arc = 1800 arc seconds.
Then just calculate your image scale using the calculator in:
astronomy.tools
(make adjustments for your optical train) - once you have this reasonably accurately: then (image scale is in arcseconds/pixel).
size of earth (pixels)= 16.514/(image scale)
This will save you the hassle of having to draw a large circle in photoshop, measure the diameter of the sun in millimetres and dividing it by 109 to get the diameter of the earth.
I am sure this has been done before, but not able to find a reference to it.
If I am wrong, then please correct my error(s).
Hope this helps.
