    @Mak the Night

    The ST80/AZ5 will be a faster grab'n'go deep sky set up for me. Although the ST102/Porta II won't be too difficult. I hope to get a lot more deep sky observing in this year.

    I wish you can get more deep sky, it's my favorite discipline, not by far but it's magical. ST102 is it equal to your 150mm in therm of light gathering. Without the obstruction they must be very close.

    @Dave In Vermont
    I think many reviewers should be told to take off their sunglasses.

    We read many strange things.. the more experience I have, the less I want to experiment by myself.

    Heck - I'd try marketing an old sock full of belly-button lint as a UHC-Filter. People would buy it if you gave it good review.

    hehehe i think that's true

    Why? So you can post an observation alongside the argument you had with your viewing partner? Hey! That could be fun!

    Bring a tape-recorder. Or a stenographer.

    Hemm I made a mistake in my previous message. I wanted to say, the more experience I have, the more I want to experiment by myself.. not the less.

    (And to be listening less to reviewers)

    Wow.

    Yes, that's what I'm counting on, plus 2" EP's.

    Lordy, Mak! You're hot on my hoofprints to catch-up with me!

    <off to buy stock stock in the ACME-Filter Company in Poindexter, Ohio!>

    Well, there is method to my madness Dave. I only have one OIII filter and I bought it for my 235mm SCT. Lumicon recommend a 200mm or larger aperture.

    lum1.jpg lum2.jpg lum3.jpg

    And as Explore Scientific claim 'Although this filter works best in reflectors of the 150mm/6-inch class and the 80mm/3-inch class of refractor and above' (sic) about their own OIII filters, I thought getting some of these for my refractors was a no brainer.

    hahahaha incredible a filter nut medail :p :)

    Allright @Mak the Night you are effective! congratulation on your explore scientific purchase. I am sure it will be a very good 2" OIII filter for the DSOs. :D

    They seem well made.

    The threads fit everything I've put them into. Bring it on Veil Nebula!

    Do you see any green color in these filters at certain angle? They look bluish, at least the 1.25" They certainly come in nice boxes . And what about the light transmission of these filters compare to UHC-S and E do you see any difference?

    Yes, there can be a greenish hue. I'd say the transmission was on par with the UHC-E, although it's early to tell. From what I can see they will be good for small refractors.

    I would be interested in a broadband 2" filter for large nebula. My NPB is a narrowband but I think I could benefit from having a lighter broadband alternative.

    A while ago you guys went crazy ;) and ordered the Orion Skyglow filter.

    --> How are they ? Have you compared them to narrow-bands and saw any differences? How is it against UHC-E from Astronomic which looks like a broadband too, and what about the Celestron UHL/LPR ? This one might be a broadband too.

    The Astronomik UHC-E is a broad narrowband, basically a narrowband for smaller apertures. The Baader UHC-S and Orion SkyGlow are broadband. The UltraBlock is a narrowband UHC. Not sure about the Celestron.

    The Orion UltraBlock® is a strange beast. It covers a transmission-spectrum differing just enough from others to make it unique. And it's a very good filter at that!

    It's strange spectra is why I also have several other UHC's - like Astronomik. Each is different, to a smaller degree, from the UltraBlock® The downside is the UltraBlock® costs a tidy sum of money.

    No clue on any Celestron filter personally.
