| Notes: | This images illustrates my current limitations .... although there are plenty of stars in this image, NGC 6888 does not "pop" out of the background as it would with a real narrowband filter! The Hoya filter more or less darkens the sky background to a level more like a darker sky location, it does not really provide much of a boost in contrast, as a real narrowband filter would. I guess sooner of later I'll have to start using my 6nm AstroDon filter .... See this link to my 14.5" Newtonian hypered Tech Pan image |
