    Default Full-Spectrum or Baader UV-IR Mod - Differences in Images ??



    I've received my T2i and packaged it for shipping to Gary Honis for Modding. But I still CAN'T DECIDE whether to go with his Baader UV-IR Filter or Clear-Glass Full Spectrum service. I'm looking to be able to perform H-a , as well as DSLR AP Imaging (which both Mods can do). I might make a few novelty Daytime IR Images, but this camera will be dedicated to AP as it frees my 60D for Daytime photography.

    Gary has been rather helpful with responses to emails, and links to images of Response Graphs and other details. Gary indicates that about 80% of his Mods are going Full-Spectrum.
    But, I've had a real hard time finding any website which has heads-up comparison images on UV-IR and Full Spectrum AP Images with anything which approaches equivalent conditions.

    I image with a mix of Reflectors and Refractors, and a few Camera Lens. This means that a good bit of the time I'd need an IR-Cut Filter to fight bloated stars - effectively negating the additional Near IR range of the Full-Spectrum. But with my Orion 8 Astrograph Newt or my C9.25, I could make full use of that Full-Spectrum "headroom".

    But, what will that "headroom" get me that the Baader UV-IR won't ??

    Which way should I go ??

    In terms of AP for both planetary and DSO work the full-spectrum mod doesn't really buy you much IMO. The full-spectrum mod is useful for terrestrial IR work.

    I may be going the "easy" route, but I'm going with the Baader UV-IR Filter (rather than the Full-Spectrum) Mod.
