Re: Solar activity of Aug 29
Thanks for your comments.
There have been several flares today too while an active region is becoming visible at NE, this afternoon I could see an eruptive prom projecting from the limb.

Thanks for your kind comments. Franco, the 100ED mod works very well for H alpha, unfortunately the scope is not nearly as good for CaK, a long focus achromat would work much better.

The region around 12833 countinues to be very interesting.

That long filament to the east of it is a nice addition to the picture. Thanks for lo...

Be very careful in dismantling that kind of objective.
