halpha sun of April 18

Good morning, everyone, a sunny sky at home but with a lot of cirrus clouds and wind and a lot of turbulence...and as, during the week, I can only make the sun late enough; a rather low target. In short, not easy, but fortunately, a little activity on our star today. At fs60 with sm40 double stack, ...

Re: halpha sun on March 9th

Hi, NR = Newton Rings, I guess? I have a problem with NR because of the glasspath. But it's gonna work out with a good tilt ring adjustment. On the other hand, the 178mm pattern is more complicated to solve ( whatever the value of gamma )... except with a flat. Here, the same picture without flat (w...

Shame about the rings. I don't think a flat is a good idea with a full disk?😞 lots of detail in the image.

good morning, everyone, the clouds came back late at night on the Albion plateau. I still managed to catch the sun in a very tiny lightening (before everything is gray!) (single 17s video! viva the 60img/s of the 178mm... and the SSD!)...)... as much to say that about the setting, there is only the ...
