Best Brand of Narrowband Nebula/Skyglow Filter?
I lost my trusty Orion Ultrablock filter, and am currently looking for
a replacement narrow-band filter. I want a general purpose filter to use with an 8" SCT that will provide the best nebula enhancement under moderately dark skies (about 1 hour outside of Los Angeles). I am looking at either getting another UltraBlock, or going with another filter such as the UHC, the Sirius Optics Neb-1, the IDAS NBN-PV, the Meade 908Narrow, the Thousand Oaks LP-2, etc. Does anyone have recommendations or comparisons? Which filter will have the best overall effect? Thanks! -- Zan Hecht |
