![]() ![]() Lumicon was recently sold and, according to all I've heard (I'm a 'Filter-Nut' and have been following this closely) - their new ones are just plain "weird." If you can find verifiable OLD stock Lumicons - toss-a-coin between Astronomik and Lumicon. The other one that I'd recommend is an OLDER Lumicon UHC. You mention in your last few words your estimated Bortle scale, getting your scope to a darker site will work wonders. Hopefully folk here, having used them on the same scope will be better equipped to advise you, but its your decision in the end. If your seeing conditions allow, I'm sure there will be a suitable UHC that will most suit your needs. The one that works will be sufficient, and will not necessarily be the most expensive one, as in my case with my choices in the eyepiece department.Īgainst some well respected brand names, some very expensive, Im more than happy with the results obtained so-far. I can tell you that you have bought a reasonable scope and if its truly your first, and depending on your locality and seeing conditions it could well be your last? until you have the desire to get a larger aperture in order to see more!Īt present, I don't use any filters, and I'll assume the decision to buy one is similar to purchasing an eyepiece ? The fact that you will only know if its the right one, after you have bought one and tested it for yourself. If someone has some personal experience here with one or more of these filters, your opinion would be very much appreciated :-) ![]() Or should I not be buying a UHC Filter for a first telescope in the first place, and just get used to the unfiltered views lol? I believe my night sky light pollution level is around level 6 to 7 (Bortle scale). I know there are broadband and narrowband (true?) UHC filters, but I guess most of the ones I listed are broadband? I've also read that broadband filters (which are more for LP than UHC I think) and especially Light Pollution filters aren't really that effective at all, especially compared to narrowband. I'd rather not spend 193 euros on the Lumicons (although I've read good reviews about those), but which one is the best one apart from the Lumicons? I've been searching a lot on Google for threads about this and UHC filters seem to be the best allrounder, but every time different filter brands and types are discussed and I just can't make up my mind with all the information out there. Thousand Oaks LP-1 and LP-2 Broadband and Narrowband Nebula Filters (€ 105) -> again Broadband probably more for LP I guess Orion UltraBlock Narrowband Filter (€ 99) Orion SkyGlow Broadband Filter (€ 79) -> more Light Pollution (LP) than UHC I guess ![]() They also have some other filters which are not categorized as UHC filters, but I think should be: The shop where I'm buying has the following UHC filters to choose from: Later ones only have a batch sample tested.I'm buying my first telescope, a Skywatcher Skyliner 8" dob, and I'm thinking of buying a 1.25" UHC filter with it to get improved views of all kinds of nebulae. The first 3 were all individually tested. ![]() I haven't seen that same deterioration in the later ones. The Livermore CA ones are all failing due to oxidation by now. In tests, the 2005-2012 filters had the narrowest bandwidths and the 2018+ filters have the highest transmissions. The 5th generation (actually more than the 5th generation-maybe the 9th-but called "Generation 3") come in a translucent plastic box with rounded corners (Rancho Cordova, CA 2016-now for the UHC and 2018-now for the O-III) The 4th generation, for a very brief period, were Chinese-made and came in squarish boxes. The 3rd generation came in the same clear/black boxes and looked the same but you could see the coatings didn't extend quite to the edge of the filter. 2001-2012 (there were more than one version in this time) Some were unlabeled, some were labeled, but all had a slightly knurled lip. The 2nd generation came in the blue boxes, and a clear version of the same box with a snap-shut and a black bottom. 1979-2001 They sold the seconds as "standard" and the decent ones as "premium". The first Lumicon filters had no labels on the filter, had rounded edges on the filter housing, and came in small square transparent blue boxes. How can you tell which Gen Lumicon filter you own ?Īre there visual distinguishing marks for each generation ? ![]()
