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!

Mirror coating for Hα reflection

Post by GreatAttractor » Fri Jun 09, 2017 11:33 am

Last spring I was in talks with Alain Badoche from MCM regarding an "ERF" mirror coating for Hα reflection (like the one in Alex Lhoest's big Newtonian), but I was unable to contact him since.

Does anyone know if another company does this kind of coating (for a cost not exceeding an equivalent stand-alone ERF, of course)? I have a nice 150 mm quartz f/7 mirror waiting...

I've got a response from Alain. Unfortunately, at the moment there are not enough customers with mirrors for him to run a coating batch. I'll keep you posted.

UPDATE:
Of course, if anyone here would be interested in getting their mirror(s) coated, it would be great!
