I recently ordered a broadband, narrowband and V-Blocking filters from
Orion. I hope I am not wasting my money. i will be using them on my Orion
Astroview 120ST.
By the way, I'm moving to Alameda from Louisiana in september and am
looking forward to finding a good club and a few observing sites. From
what I can tell there are a few sites that most people go to. Fremont Peak
seems to be the most popular. When I finally get set up in Alameda is
there a place I can go to get info on these sites and the various bay area
clubs?

My least useful filter is the H-Beta supposedly used for viewing B33, the
Horsehead. I think I tried it once and then I yawned. BTW, I'll sell it
for %65 of list if anyone is interested.
