Full disk mosaic in hydrogen alpha on Sep 11th 2022

Post by cmas »

This is my last solar image for 2022 as the sun is dropping low in the sky and the weather is just plain bad for any astro at the moment. I tried to get a proper mosaic of the sun and while there are some aspects in the uniformity of the mosaic I consider this as a nice end to the season. The images are quite big, about 10 000 x 5000 pixels so full size images take some time to load. And more details in AstroBin.

Yep. The altitude does not really support even my equipment's full potential anymore.

I updated the images today as I think I was able to make some issues a bit better. Also checked that by combining the BW and color versions I could make print of about 90 x 90 cm at 300 dpi.

And thanks for the comments to all! As always they are highly appreciated:)

These are really great Tommy ! Definitely the sun is starting to get lower these days. Where I am, though, I can continue for a while.
