I did some test imaging this morning of both the moon and venus.  Both red and Ha filters worked fine, although I felt that the Ha was more successful – don’t ask me why! The key thing is that the moon requires one tenth of the shutter speed of that venus needs.  So the choice is an over-exposed venus or very faint moon. In my case the moon was best at around 0.3s with the Ha filter, and Venus at 0.03s.  I’m tempted to try with both exposures on Friday, and then combine the images.
