Good point about the ultra-hard scratch resistant coatings. I just recieved my bintel filters & can confirm that giving them a good rub with a lense pen does a good job getting rid of fingerprints leaving no visible marks.
Performance wise...first time I ever used a filter so cannot compare. I don't mind the green effect, however have to question the over all result. My skys are reasonably light polluted, but I am using a 12" scope. (perhaps that only exasabates the problem) M42 seemed bigger for the better part without the filter. With the filter I guess I could make out the darker regions within the nebula, but then once I did that, I could then see those regions without it. (that said though...If I wish to find somthing that does not really stand out, I guess the filter has its use) MMMMMMM...using a higher MAG did start to bring out more of the 3D effect many talk about...more like a puffy cloud effect that I could apprecieate. Seeing conditions were very moist & I beleive I can get better results. As for a LPR I dont think it really rates...either I have to much light pollution or you simply get what you pay for...a UHC not a LPR...not sure about that.
I am glad I got the bintel version, as I think I need to learn how to use my filters like using an eye piece...if ya know what I mean. In sumary I think it will be usefull for picking out finer detail that simply does not jump out and grab me in normal mode whilst in light polluted areas. I am curious as to how the puffy cloud effect will work in dark skies. Perhaps this is where I will have better results at lower power.
Have not tried the OIII version yet...that will be next on the opropriate target?
Regards
Dave
