I had a bit of a look at the helix nebula tonight. It was a nice round disk, and with averted vision I could see the dark spot in the middle.
I'm looking at buying a nebula filter, what would be better to buy a UHC or an O111? Also would a broadband filter help bring out detail in the galaxies?

Hi Andrew,
Have a look at Scott Tannehill's article on IIS about modifying your scope to cool the front of the primary. This is a very easy modification (and it will tell you where to get a fan). My scope came with a fan, but this mod made a huge difference to the scope's performance.
Also I have a UHC filter which does bring out more detail on nebulae, but I don't think you'll be blown away by its effects on galaxies. Even with nebulae, Is till often prefer an unfiltered view. I have found the biggest boost to my capacity to see detail in galaxies is practice in observation. I would suggest that you don't rush into spending on things, just keep looking (using averted vision) and you will see more and more, especially with the dark skies I would expect you have. You will be amazed at what you find over time.
