Hi Guys,

I'm new here, last year I bought a 8" GSO Cob from Andrews Communication and have recently been getting into it all lost more than when I first bought it. I've only got two eyepieces (25mm and 9mm which came with the scope) and a 2x Barlow.

Recently I've been viewing from my brisbane backyard and have enjoyed seeing soem clusters especially in Scorpious and Sagittarious, but have found the nebulars quite dissappointing (as you'd expect from the city).

I'll soon be travelling in the US and am conisdering buying a nebular (Narrowband) filter (along with a few more eyepieces) to improve observations from my backyard. Can anyone advise me on what improvement I can expect from my 8" Dob, on the lagoon nebular for example which last night was simply a cluster of stars with virtually no nebular?

How marked is the improvement in an 8" scope?

thanks,
Dan

p.s. I'm considering the Orion Ultrablock 1.25" for US$65. any word on this filter, Thanks again
