Hi Bert
Thanks.
It may well do so, the filter would have to be perfectly light tight. The other day I tried to get Mercury with solar filter on, but light leakage (not from the sun but light coming in from the side) ruined it.
Not much sun falls on the mirror so far, but the comet is closing on the sun and I will be careful. The closest ive been to the sun without a filter was imaging Venus 3 days before the Transit. That day, the sun was focussilg to a point 1/2 way between the secondary and the tube (yes I was VERY careful that day)
Scott
PS, thanks venus too
