September 11 2020 Observations. Excellent seeing!!
Today my wife has plans for me on moving some stuff for her daughter and I did not have time to set up my bigger pair of solar instruments. That's a shame. Seeing conditions this morning are about the best I have seen all year. Skies are a hazy bluish white and the temp is 76F. Session time is a short 10:30am to 11:15am EDT local time ( US ). Skies are clear of clouds.
Coronado SolarMax II 60 DS. 16x, 21.5x, 33x and 50x ( Ha )
I can see 5 prominences around the limb even in double-stack. Two in the northeast are easy to see. One in the southeast looks to me like a dissipating mushroom cloud. I also see a small group in the NW without difficulty. The SW shows the hardest ones. Faint in D.S. I see no plages on the disc and only one filament in the northwest. I can faintly see the spicule layer in D.S.! The spicule mottles show good contrast today.
Orion 70mm Solar Telescope. 25x, 50x and 62.5x ( WL )
Remarkably I am picking up polar faculae with a 70mm scope! They are supposed to be difficult with anything under a 4" instrument. I can see several in the north polar region. Not hinting them either. I can see with greater difficulty only one in the south polar region. The superb seeing is no doubt making a difference here. Granulation is really easy to see also though a larger scope with higher magnification would really benefit me here. Otherwise the sun is featureless. No spots or pores.
Carpe Lumen!

Wow!! sounds like a killer solar session!!! all those proms and WL polar faculae
I would tell the wife to go and do it herself no, I never said that

Lol!!! I should have. Then I could have used the 90 and 102 in those awesome seeing conditions.

Re: September 11 2020 Observations. Excellent seeing!!
" Observing polar faculae is not an easy job. Moreover, years of experience have shown that in order to obtain reliable and comparable observations, a couple of conditions need to be met: Observing should occur with a telescope having a diameter of 4 inch (10 cm) or more. It is highly recommended to use a glass objective filter, or alternatively for the refractors, a solar/penta prism or Herschel wedge. Solar screens tend to diffuse the light, whereas the projection method is heavily affected by stray light from external sources. Therefore, both methods are significantly poor in contrast, and thus quite unreliable for polar faculae observation. Needless to say that an ocular filter in combination with these high-diameter telescopes constitutes a permanent threat to eye-safety.
Observing conditions should reach at least 3 (preferably 4 or 5) on the SIDC-seeing scale, which means significant detail should be visible in even small sunspot groups, and one should also have a good view on the solar granulation. The eventual aim is to have a direct view of the solar surface as crisp as possible. "

Hi James,
Well done and that is how it has looked in my place since my last discs from September 3
