The Eta Carina nebula is my favourite and my most watched object in the sky. The star is slowly and steadily getting brighter. In 2007 it was 5.7 mag, then in 2008 it gradually brightened to 4 mag. As of a month ago, it had brightened from 4.65 to 4.55. Through my 6" dob. with a 10mm ep (120x mag) I can clearly make out the elongated shape of this star.
Alexander, I will be interested in your follow up with looking through the 8", regarding details and also the nebula filter. I have just purchased a UHC filter and not been able to use it due to bad weather (I hope it will work on this neb).
You are very fortunate to have such a large aperture to truly appreciate the beauty of this nebula.
I am trying to find a book at the moment that will explain all these details I need to be looking for within objects (observational astronomy). Something that will challenge my viewing. If anyone has got any recommendations, would you kindly please drop a line into my current thread in "Astronomy Books & Media".
