    Unhappy Sourcing Out Lumicon UHC & OIII 1.25" Filters



    Hello all - long time I don't post!
    I've just ordered a Skywatcher Explorer 300PDS NEQ6 Pro from Rother Valley Optics with a power tank, a coma corrector and some Pentax XW eyepieces. Needless to say I'm excited to receive it all!!
    What I'm now desperate for is Lumicon UHC & OIII 1.25" filters. I've read a lot about nebula filters and have concluded these are the ones I definitely want to get. Rother Valley Optics has been out of stock for the past 7 months apparently and so I decided to give Lumicon in California a call. They informed me they too are out of stock due to the filters having been destroyed in a tsunami...

    My question now is - does anyone know where I can buy these filters?
    I don't mind what country they come from as long as I can get them to ship to Gibraltar (even if I have to arrange my own courier as I'm currently doing for my telescope with Rother Valley Optics). Hell I'm even easy about price at this stage, I just really want those two filters (1.25" size). I refer to these two in the unlikely scenario someone isn't sure which ones I mean exactly:

    Lumicon UHC 1.25": Filter Ultra High Contrast 1.25in - Specialty Telescope Filters
    Lumicon OIII 1.25": Filter Oxygen III 1.25in - Specialty Telescope Filters

    Hopefully someone can help me out while I continue my seemingly endless search. Thank you very much in advance!

    Hello Gib007,

    have a look at TS,

    Lumicon UHC Filter - 1,25' - fr Fotografie und Beobachtung

    OptikPro,

    Lumicon OIII Filter 2''

    and Astroshop.de

    The UHC Lumicon filter seem to be still available, and also some (2") OIII Lumicons. Nobody knows, if Lumicon will restart the production in 2013, or if they will offer filters made by other manufacturers.

    Just an add-on to the Lumicon OIII,

    Lumicon OIII Filter 1,25 | eBay

    It looks like the dealers in Germany would through the Lumicons on the ebay.

    JG, thanks very much for taking the time to reply with some links, I appreciate it!
    I hope Lumicon get it back together in 2013, indeed. I have read around more and have noted that DGM Optics make even better filters than Lumicon with smaller FWHMs in the narrowband. DGM Optics even sell their filters via their own store on eBay so I have just ordered DGM Optics's NPB and OIII filters (equivalent to Lumicon's UHC and OIII filters, respectively). Reviews I've read seem to indicate they produce even better contrast than Lumicon's offerings.

    The NPB filter cost me £60.74 with shipping from the USA and the OIII filter cost me £67.34 with shipping from the USA. Total £128.08 for both - score!
    I was ready to pay £86.80 per Lumicon filter at Rother Valley Optics so I'm very happy with this result..

    Hello Gib007,

    congratulations. The DGM filters are an excellent choice.

    As others may also read this thread, below find the transmission curves of the very narrow-band OIII filters, including the DGM

    http://www.karmalimbo.com/aro/pics/filters/o3b.jpg

    Clearly, the DGM OIII will beat the Lumicon OIII on the fast scopes (like f/5), due to the so called blue shift of the narrow pass-bands. The reason is, the Lumicon OIII is too close to the main OIII line at 500.7nm, and the long wavelength cutting edege of the Lumicon may easily touch the emission line, or even intersect it. The difference between the both filters will be less on the slow scopes (f/8 and larger).

    The DGM NPB vs Lumicon UHC is here,

    http://www.karmalimbo.com/aro/pics/filters/narrow.jpg

    The both UHC filters are not CCD filters, and they may transmit some unwanted light in red and in UV, and as it used to have been with Lumicon, one production batch may considerably differ from the other. However besides the perfectionists, hardly anybody will worry about it.

    Looking forward to your observational reports on the DGM filters,

    Thank you very much for all the information and the graphs. It's very interesting to have a look at the specific transmittances of different filters at varying wavelength. The telescope I've bought is an f/5 so I'm looking forward to seeing the difference with and without the filters. I'm really glad there are amazing alternatives to Lumicon's filters as getting hold of Lumicon filters today was depressing me!
    I will report back once I receive everything although I do not have Lumicon filters to compare with so all I can give is a general consensus of clarity with the DGM Optics filters.

    Hello Gib007,

    with the DGM filters you can't go wrong, some people regard them as better if compared with the Lumicons.

    Regarding the curves, they are a sort of general information on what performance can be expected using different filters.

    Once again, I can't wait on your observational reports, as the DGM filters may be of interest for lots of the folks here.

    What's the VAT/duty situation like in Gibraltar? If it's like the UK, you'll get stung for VAT on cost including shipping, plus any duty...

    I lived in the UK for 8 years so I've been constantly stung for money for everything!
    In Gibraltar we have 0% VAT and the government just slashed most import duty. Photographic equipment, what all astronomy stuff qualifies as, has 0% import duty. What I paid on eBay for the filters is therefore going to be it. Same with the 0% VAT cost for my telescope and everything else from Rother Valley Optics.

    Actually I heard from a very good source that Lumicon is still around. They have been going through some major restructuring and have a lot of filters and other products in production. So, yes, they will definitely be around for 2013!! Definitely worth the wait for me!
