The mirror of my scope is now pristine, to keep glare down. 3 days before the transit of venus, I observed venus as a very thin crescent, so close to the Sun, that sunlight was falling on the primary mirror, and focussing to a point roughly 1/2 way between the secondary and the tube, actually that was ideal as it wasnt going to damage anything. If it was a bit further out it would have fell on the tube and possibly damaged the paint on the inside. I had the drive locked on securely to prevent any chance of the focussed sunlight falling on the secondary (either blinding the observer or wrecking the camera) I will again be especialy careful when trying for this comet. I only hope to see some clear skies, cant believe the amount of cloud this last month. It will be real exciting to get a clear sky at perihelion day and have the comet brighten into negative magnitudes
