Filters....

[johnkirkpatrick]

I am getting a 300p skyliner. and was gona get a filter, the OIII or the UHC skywatcher, which is best for a larger scope? I need it to tease out more detail in galaxies and nebulae

Those filters won't help on galaxies - no filters do - just dark skies and aperture. On nebulae though they are very useful on certain types, notably planetary nebulae and supernova remnants. With 12" of aperture the O-III is probably the most effective.

I use the Orion Ultrablock (within the limitations that John says)

(I think it came out best in a S@N review of these things...)

If you don't have any LP filters already then an UHC is probably the most useful. The OIII is a slightly more specialised filter. Not all UHC filters are born equal however. Some will work better than others. Do some reading of reviews before you choose.

I find it weird that neither the OIII or UHC from skywatcher helped on the veil (OIII / UHC Filters) as this is a target that is well known to respond well to OIII. I never view it without a filter in fact (even from mag 7 skies).

Another possibility are the DGM filters (Welcome To DGM Optics) Their nebular filter (NPB) is very well thought of. At least as good as Lumicon's offering and cheaper. I have one and like it a lot. Don't be put off by the weird website and the E-Bay store. They're good products.

hi john i have an astronomick lp filter , they are very good quality

[johnkirkpatrick]

Still not sure what to get lol, What would you get? the UHC or OIII? I will get the polarizing moon filter or is the cheap one on FLO just as good?

Why is decision making always hard when it comes to astronomy. First I went gray choosing a scope, Then I pulled my hair out choosing EP's, Now the dam filters are driving me mad lol, This hobby is ment to be relaxing!!
