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!

Although a little hazy and not much solar excitement, it was nice to get some sunshine. Images were taken with a LS 80 with and without a 5x Powermate and although the scope lacks the wow factor, it sure beats just staring at the Sun.
Here's my take on the 13th of January.

Hi Phil,

Very good images. Like the full disc. Maybe atiny trial in better tuning ¿? I know it is difficult with the famous little golden wheels ...

Nice set of images, Phil. I wouldn't say they lack any "wow factor", especially the closeups look brilliant.

Really nice collection of images Phil. The scope definitely has a wow to it.

Nice images, Phil.

Your full disks are beautifully uniform. Nice close views too.

These are super Phil :hamster: :bow

I know what you mean about the full disc, after seeing Rainer's DS full disc I have never been quite happy with my Solarscopes recently. I spent ages tuning and I can't replicate Rainer's, my full discs are very similar in bandwidth to yours.

Thanks for the kind comments and encouragement. Much appreciated.
Rainer, I agree that tuning could use a little adjusting. With the pressure tuning controls it seems I get tired of turning the knobs berore it gets tuned properly. I will persevere.
Alexandra, I have never noticed a bandwidth issue in your images. With this little Lunt scope, I can address the tuning but the bandwith is what it is. Sometimes perfection seems just out of reach.

Thanks again, and clear skies.

Phil

Great discs, the first image is particularly well balanced.

A great looking set, Phil. The Lunt 80 is a great scope for this.
