These are 3 interesting, albeit difficult objects in Taurus, all lying very close to the Taurus Dark Cloud.
PK 174-14.1 - PN - vf, ps, looks somewhat elongated. I'd love to find a photo of this to see if my "elongated" suspicions are correct. Best with OIII, next best is Orion UltraBlock, followed oddly by Lumicon Deep Sky and trailing behind is the Lumicon UHC. Strange indeed. It's also visible with no filter, but far more satisfying with.
IC 2087 - Bright Diffuse Nebula vf, vl, quite oval in shape. Best without any filters, though the UltraBlock seems the best of all the filters. You might have to "wiggle" the scope a bit to get this illusive object to show up.
B222 - Inky black region surrounding, and just east of, an 8th magnitude star. My best magnification was 120x.
Has anyone seen any of these?
