July 7, 2015: Eleventh mosaic!


Recommended Posts

If the forecast is to be believed, this may be the last one in the amazing sequence of one full-disk mosaic per day. I know I have said that before, so tomorrow morning I shall simply see what the weather looks like. Today it was clear, but seeing was a bit wobbly. Later it got more stable (unusual) and I grabbed some detail shots before clouds rushed in (I will post those later). This was taken with the usual APM 80mm + Solar Spectrum H-alpha filter (working at 1920mm focal length and F/25.6 or 75mm aperture).

Grey scale:

file.php?id=15379&mode=view

Part inverted:

file.php?id=15380&mode=view

Pseudo colour:

file.php?id=15381&mode=view

Part inverted + pseudo colour:

file.php?id=15382&mode=view

I will add this and the previous one to the animation later.

Another nice one.  We had rain here (Bordeaux-ish) today that wasn't forecast at all, so you never know, perhaps your non-cooperative weather won't arrive...
