prominences with wide slit spectroscope

Post by ChrisHalpha2017 »

hello,
I'm back with my spectro-coronagraph as the sun in now peering through my window sill under the roof in Paris at the right angle to allow me to watch the sun ^^

here are some of my new photos...

The sky was very hazy most of the days and I had to use the 2400 lines/mm grating if I wanted to record or even see anything. When I use this grating the doppler shifting becomes very apparent and the images are somewhat blurred but I can see spicules better and the contrast is enhanced.

When I use the 600 lines the images are the sharpest but so far 1800 lines/mm was the best compromise depending on the conditions.
