Hello, I have Schuller 1.25" photometry filters. I left them at their original plastic cups for 4 months in a drawer. When I opened and look at the filters-...
Hi Ido... I can't say what the crystalls could be...probably an oxidation reaction. I have had my Schuler set for 2-3 years with no troubles, even in a...

... a ... Is this coating on the exterior surfaces, or does it look like it's inside? You may have to look closely with a magnifying lens at the surfaces in...
Don, It is on the exterior surfaces. From a first examination it looks like a pretty hard material to clean. Is there a special cleaner fot this couse? Thank...
Ido, sorry for not replying sooner. With the new change in the Yahoo format, I'm logging in less and less. Did you contact Schuler Astro Imaging? My...
I have just purchased what is supposed to be a used Lumicon Deep Sky Filter. Unfortunately the filter does not have anything engraved on it that says it is a...
Hi Ed, I had one and from your description it sounds like the one I had. I bought mine directly from Lumicon so its seems you got the real deal. I was not all...
If you could recommend only 4 planetary filters, which would they be? I am planning on buying just 4 but looking at all the different Wratten numbers they ALL...
I have had two very interesting conversations with Lumicon personnel about their filters. They say that EVERY filter they have ever manufactured and sold for...
Ed, You might want to try the Baader contrast booster. I only have a preference for the yellow 11 in wrattan filters. Not a big filter fan for planets. As...
good info, I thought you indicated you had bought one directly from Lumicon and it didn't have a label? Kevin ... personnel ... doesn't ... (800) ... name ......
No, I bought one on EBay and it didn't have the word Lumicon etched into the metal ring. That was what made me suspicious. Others have posted on this and other...
Hi Ed, I beg to disagree with the current employees of Lumicon, a company that was bought out from the original owner, Dr. Marling whose day job in the 1980's...
Craigs observations are correct. I have a 67mm minus violet filter I purchased in 1986 directly from Lumicon. No markings on the metal ring, not even a...
Folks, I have just spoken again with "Mike," who identifies himself as the General Manager of Lumicon International. Here is what he has to say. Much of the...
Dear Ed... The historical Lumicon info you gleaned looks very complete and should prove useful to others evaluating older filters. Thanks for posting the...
This was funny. Obviously spam, but "close" to being on topic Lol. With the money I have invested in astro gear I was tempted to check out the site. It's odd...
When I see these 'helpful' messages, I get a mental image of a wild chimp slamming a keyboard to get his ID. No rational chimp would use such daffy ID's Dennis...
I wouldn't worry too much. Spam like this comes in waves, then quickly dies out. The spam spawning robots move onto other targets. Also Yahoo's counter-robots...
Hi, a newbie here.. I 'm in the process of picking up a used Sac-8 II cam and figure eventually i'm going to need a set of filters for it. Apparently it seems...
I would recommend astronomik or astrodon. The former are superb value, the latter are considered best by some but much more expensive. Clear skies, Kevin ... ...
Hutech makes a 8nm halpha filter that "drops into" the canon DSLR. I'm thinking of trying it out. I'm presuming this is an IDAS/Kenko Halpha (seems to have the...
Hi Jeff, have a look at the Astronomik filters. We do have a 13nm FWHM H-Alpha filter and we will ship our new 6nm FWHM H-Alpha in the mid of june. As far as I...
Dear Jeff, I own IDAS LPS and Kenko 64 but do not have a modified EOS DSLR to try out the Ha imaging. According to my rough calculation using their ...
