    Gooday all , A short question , has anyone used these filters (Orion 1.25" Specialized 3-Piece Planetary Imaging Filter Set) and if so what were the results like. Also are they meant as a replacement for RGB filters or in conjunction with RGB filters . I am about to purchase a set of filters for planetary imaging but there is such a large choice its difficult to decide which manufacturer will deliver the best result.
    Any advice most welcome.
    Thanks MarkB

    Hi Mark,

    I have not used this particular Orion filter set, however I have frequently imaged the planets, Moon, and Sun using an IR high pass filter. As mentioned in the product description on the Orion site, the two filters that are in the IR band (above 650nm) will have the effect of steadying the atmospheric unsteadiness (seeing), allowing a big improvement in your ability to get a sharp focus and the detail visible in your images. I know from experience that this is true. You will also see quite a difference in the appearance of the planets; dark bands may become light, Saturn's rings become brighter, moons become brighter. These are not a replacement for RGB filters, they are in addition to...just another way of looking at things. The UV filter will be challenging to use because atmospheric turbulence is worse at the shorter wavelengths. Focusing will be difficult except on the most steady of nights. For the best results I highly recommend getting a sensitive planetary imaging camera and use the "lucky imaging" technique, ie. record 100's to 1000's of frames and use software to pick out and stack the best frames.

    Best Regards,

    Jim T.

    Jim Thanks for the advice I suspected but was not sure they would be an addition to the RGB imaging train but far from sure .
    I will give these a miss and look for a quality set of Lrgb filters.

    I see Astrodon do an expensive set but is price a good indicator of quality?

    I presently use a number of different cameras for imaging including an Imagingsource DMK21au618.as mounted on a CPC800 and use the "lucky imaging" technique to obtain photos of the planets but I never seem able to get sharp enough subs or a good overall color cast . This I think is due to the filters which were a "give away" when I purchased the CPC.

    Hi Mark,

    Astrodon do make a good quality filter, but you can get equally high quality filters at a lower price from other manufacturers. I am a long standing supporter of Baader Planetarium filters. They are very high quality/high performance and are sold at a more reasonable price. I don't have any direct experience with using LRGB filters and a monochrome camera. All my imaging work has been with one-shot colour. I have been using a DBK51 for several years but just recently upgraded to a ZWO ASI185MC.

    cheers,

    Jim T.

    If you are concerned with reflections and halos, then buy Astrodon Gen2 filters, they are the best. I have had many sets of LRGB and Narrowband filters.

    Jim, it's nice to see your post here. Hopefully your next one will be about your much anticipated astro camera comparison. For those here who are un-/under- initiated, Jim wrote a very exhaustive, very informative, published comparative study of various filters which he graciously shares with everyone on his website http://karmalimbo.com/aro/. Check it out; you won't be disappointed.:)
