Hello Group I am new to this group so please bear with me. My question is regarding a 50.8/2" filter housing :- What is the thread on the end and is there a...
I assume you are asking about the standard astro 2" eyepiece filters. These have a 48mm thread, no clue regarding threads per inch, but any adapter that's for...
Forgot that haze. Even at the darkest site on Earth you will still get a nasty red haze in properly exposed deep sky photos. Before spending money on, eg IDAS...
I shot this odd view of M42 a few nights ago. It was a project I have wanted to do for some time. I used Near IR for red (825nm longpass), [SulfurII] for green...
Hi Kevin, I tried the Continuum filter out on the sun a few times. Like with most other filters, the result is an incremental improvement for solar observing,...
Hello Everyone... I have posted my first 'successfull' images this year of Jupiter and Saturn in the MapleRidge folder of the photos section. There is one...
Thanks for the follow up, I appreciate it. I just have not had the time to get around to this project. Based on your results, I think I will borrow one...
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...

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...

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...
