Venus Transit hint ..

Been testing my solar converted scope for next Wednesday. There is an N5 Baader Solar Filter inside the light sheild. It was still very bright so I placed the lens cap on with the centre hole exposed. This helped quite a bit so I got creative and added the 13% moon filter back at the eyepiece.

Worked a charm. It not only cut the glare back but improved the contrast, made the sunspots stand out more and gave the sun a yellowy green tinge which was much easier to view instead of the bright white. So I took a picture with the little P&S Fujifilm through the lens.

Heres my setup and a sun. If you look carefully you can see the sunspots. On the original pix they are quite discernible as is the surface boiling and the lighter area around the sunspots.

That's a TMB Planetary 9mm back on the diagonal. Enough to fill about 60% of the FOV but give time for the suns movement through the feild.

Also you don't need no fancy sun finder. Just look behind the scope in the first pic and you will see the shadow on the ground. Just look back and line it up. I hit the target every time.
So take your moon filter with you. I'm going to try a few others to see what they do for contrast or showing up any other features. Shame the N5 is not suitable for prominences because this is getting interesting.
