Some nice details there Greg

I am going to the US in May to the Texas Star Party with a few astro mates and as part of our trip we have booked a whole night observing on the Hooker 100" scope at Mt Wilson (for just four of us!!)...and even given its slightly southern declination, M104 will be nicely placed, so I can't wait to see what it looks like through a 2.5m telescope under (hopefully) some good seeing that Mt Wilson can get
