Manged to get out for an hour

[lunator]

Fianlly the clouds broke.

I managed to get out for an hour tonight.

The moon was just above the houses but the earthshine was beautiful

I had a brief look at Mars & Gamma Aries.

I went back to STF196CD. This star has not been measured since 1983.

I measured it in December but I could not get a sensible answer from the calculations. I rechecked my timings tonight and they agreed with my other set.

It clouded over after an hour and I went inside to re-assess my Calc's It was then that I realised that I was dividing by the field diameter not the radius

It finally made sense.

If people are interested I will outline the calculations.

Cheers

Ian
