Solar Analemma. This outstanding image from Alexandra Hart taken over a period of 4 years charts the midday position of the sun in the sky throughout the year. The north–south component of the analemma results from the change in the Sun's declination due to the tilt of Earth's axis of rotation. The east–west component results from the nonuniform rate of change of the Sun's right ascension, governed by combined effects of Earth's axial tilt and orbital eccentricity.

Merry Christmas, Happy New Year and looking forward to a great solar cycle 25!

Full Disk and prominence 15/01/2020

Post by salvo lauricella » Wed Jan 15, 2020 1:16 pm

Hello everybody, here are some photos of the Sun taken with a Lunt LS60THaPT/B1200, a Powermate 2,5X with the Grasshopper3 GS3-U3-28S4M.
Not much to see just an interesting prominence.

Regards

Salvo, I enjoy your images very much. Especially since I am new to solar viewing/imaging with the same telescope, Lunt 60THa. Do use dark and flat field frames? Again nice imaging!

Thank you guys for your nice words.
I don't use darks and flats; I use an artificial flat during processing.
