  1. This was my third attempt. Earlier tries were with the SeeStar S30 and the result was too small for any real detail. The Seestar S50 is great for these smaller deep sky objects.

    S50 w/EQ mount. 5.5 hours over two nights 191 30-second subs wtih LP filter.

    PixInsight:

    * WeightedBatchPreProcessing(WBPP) with 1x (.9 drop shrink) drizzle,
    * SPCC,
    * Dynamic Background Extraction(DBE),
    * RC Astro’s BlurXterminator, NoiseXTerminator and StarXTerminator,
    * GeneralizedHyperbolicStretch and CurvesTransformation,
    * More BXT and NXT on starless and stars images
    * Seti Astro’s StarStretch,
    * PixelMath

  2. First, awesome shot, the sea stars cease to amaze me, easily best bang for buck in this hobby.

    Second, Damn, what the heck is the FL on that bad boy? I have been shying away from this because it looks like even with my 850mm scope it will be rough to get a shot worth all the effort.
